At the end when it was reassembled,what the first issue was that the firing rod was extended,if anyone else runs into this,just remove nails and dry fire it it resets the rod position :) great video btw!!
There are no schematics. Most of the tools use a planetary gearbox arrangement where there are 3 cogs in the centre where the motor shaft goes with an outer cog, this then usually connects to another similar set (I disassembled a drill some time ago)
Thank you sir. I took a gamble on Milwaukee battery powered tools. Replaced all my pneumatics and corded power tools with Milwaukee platform. If a pneumatic gun goes down, it's easy to order parts and they are not nearly as expensive to replace. So, upon trimming my third house using the battery platform, when my 18 gauge lost it's oomph, I was heartbroken that I may have to dish out 300 bux for a replacement. Hopefully, this video will prove to be helpful.

Got to thank you for making this video. saved me money and so much trouble being able to fix my gun myself! Just sat down and played this video as I went.
That's great. I'm sure mine will need topping up one day. The Hikoki version has an external port access on it to re-air. Shame Milwaukee didn't do that too. Cleaning it probably helped a lot too.
Think mines coming apart this weekend. The extreme cold affects the tools performance, doesn't sink nails as well. Think mine might just need a little air to top it up.
Awesome video. I love Milwaukee tools, but for the life of me after seeing your tear down I cant see why Milwaukee decided to have the compression tank exposed like that and also make it so hard to service the tank as well.
They do. It's just not accessible without taking the tool apart. The silver metal piece is the dust cap, and under that where I screw the filler adapter is the shrader valve. I don't think they expect the average user to repair these.
Awesome video, my nail gun seems to be lacking a bit of power from when it was new. Especially first thing in the morning. Gonna tear it apart this weekend. Thanks for the help sir!!!
@BuyitFixit hi I was wondering when u fill it up with the compressor u let the compressor fill up till 160psi and then u let all the air in or just some air
Je suis français, et nul en anglais mais j'ai suivi ta vidéo très bien faite, qui m'a permis de réparer un cloueur Milwaukee que j'avais acheté 150€ à réparer sur un site ....un grand merci, j'ai un cloueur de finition qui fonctionne parfaitement pour 150€.
You're welcome 🙂Air is 80% nitrogen...I did read they used nitrogen to help with variations in the nail depths due to temperature not sure how much difference it makes in the real world though.
Brilliant news Kevin! I'm really pleased that you managed to get your gun working again. The finishing gun needs less PSI than this one. I think it was around 90 to 110 PSI if I remember.
I've got a broke one here.. not looked at it yet but will be doing a video on that and a crown stapler too. Ive got a few other things as well,also just fixed a couple of different radios.
There is a simpler way, turn the bell 90° and drill a 15mm hole in the gun shell, opposite the inscriptions, to put the valve on the outside. This way it is possible to repressurize at any time without disassembling the housing.
Where can I buy that pump or a fitting to fill the canister? Amazing video! Our team runs about 7 of these guns and we always have one out of commission getting serviced but by the looks it’s super easy to give it a quick re-gas
Hi, Found your vids really helpful. It's hard to have these filled with nitrogen as I'm not sure if there is a maximum psi lable on cylinder. So tyre or diving shops are reluctant to touch. Theses no info around to give maximum psi that you kindly supplied. So air pump it is. Did you use some kind of regulator on that pump. As it's hard to get an accurate 160 psi with a gauge that goes up into the 4000's
Thanks 👍. I was told around 160psi, but s viewer recently said he thought it was too much and around 120psi was better. You can always start lower and add a few more pumps you think it's not powerful enough. Yes it was hard to gauge on the gauge as you said due to the scale.
Do you think the narrow 1/4 crown stapler gun m18 also works the same as these ? So how often those this maintenance has to been done ? And one big quest does Milwaukee warranty cover this service of the refill of air or there’s is a cost even the 3/5 years warranty , so you used just a compressor to fill up no special gas like nitrogen? I saw the ryobi version brush but they use the same motor to sort of compres the air in like a chamber no need of compressor which is good and bad as idont know how deep can the brad or staples can penetrate the material. But I learn a lot just by watching you video
Thank you. I've also bought a broken 2nd fix nail gun and a crown stapler to do videos on, so I guess we'll find out soon! I've been busy with other things the last week so haven't had a chance to do videos lately. Stay tuned as there's more coming!
You fix all the milwaukee trouble the super saw all i dont understand how you do but you do it ! My cir saw rear handle did the same as the supersawall video... also my fraiming nailer have do this also
You reckon an ATS branch would fill the canister with their Nitrogen tyre inflation kit ?? perhaps they're limited to too low pressure as tyres aren't inflate to anything like 160psi would probably need some sort of adapter too
I did see nitrogen kits on Ebay for aircon. They might have enough pressure but I've not tried one. I personally would just fill it with air it's 80% Nitrogen anyway.
Check the video description I did put some more info in there. Search on Amazon or such for stirrup pump you should find one the same as the one I used or very similar.
@@BuyitFixit It seems I made a mistake and put some lithium grease into that chain wheel, don't know what happened in the future. Do you know what's the size of the inflator threat? Thank you so much
@@狮子子 as far as I know its 1/8" I used an air rifle stirrup pump and the adapter was just a straight through coupler. The air pressure will open the valve.
This is a great video thanks, I tried pumping it up with a bike pump with a adapter I managed to sort but I can’t get any pressure in the gun at all can you help thanks
Unfortunately I dont think a bike pump is up to the job. You need about 160 PSI and most bike wheels are around 30 PSI which is why I used an air rifle pump.
@@BuyitFixit I have got a small bike suspension pump which goes up to 200psi but the won’t work either, iv ordered a air rifle pump now so fingers crossed that will work thanks
Have you stripped it down like I did in the video? The only thing I can think that would stop it holding a charge would be worn seals or a cracked or worn barrel. You should be able to hear the air escaping in either case.
@@BuyitFixit yes it’s all been stripped and cleaned and no broken seals, does the air valve pin in the middle have to be pushed in to allow air in as the adapter I have isn’t long enough to push the pin in thanks
Originally they are supposed to be filled with Nitrogen (apparently to stop thermal variations in pressure) but seeing as air is 80% Nitrogen anyway I doubt you would notice any real difference unless you were working in Antarctica and then going to the Sahara!
Normal car tyres wouldn't need that sort of pressure, this is a small cylinder with a piston that's hammering a nail into quite solid wood hence the high pressure 🙂
Great video. I have one just like this but as well as the power dropping (probably lost gas pressure) it's just stopped firing almost entirely. It fires very occasionally after holding the trigger for ages and waggling it around a fair bit. Any ideas why?
@@BuyitFixit yes, I'm afraid that might be the problem. Funny how the faults pile up with things like this! Going to try a teardown and clean later so will hopefully find out what's going on. I wish I had an air rifle pump like yours though!
So the trigger switch works, but gets misaligned easily. I think it's a bit of a design flaw that they overcome with hot glue in the factory. Managed to open up the gas cylinder to find it full of condensation - a sure sign that someone has already tried to regas it themselves. Got it repressurised but not high enough. Trying again later.
@@BuyitFixit got it pressurised up to 160psi (hard work with a mini bike pump!) and it seems to be back up to full power. Very pleased. I just wish the tool had a maintenance mode like the Hikoki/Metabo nailers so the firing rod extends all the way out for resgassing. Annoying having to dismantle it each time.
@BuyItFixIt where did you find the psi setting for the different nailers i have a M18 FUEL 16GA STRAIGHT FINISH NAILER 2741-20 and i believe this is the issue i just am not sure what psi to use. Was there somewhere you found this information?
There's no definitive information as such, however you can start low then increase the pressure until it works correctly. I spoke to someone else who had repaired a few of these at the time, and he said around 160psi for this gun and around 120psi for the smaller guns.
They usually fill them with Nitrogen but since air contains about 78% Nitrogen I guess that will work fine. What I wonder is are the two sealing rings symmetrical or do they have a specific orientation just like an Automotive Piston rings?
I'm not sure about the rings orientation, but yes agree with the 78% nitrogen. When I looked into it at the time it said somewhere that it was to stop variations in pressure due to different temperatures which probably wouldn't make a lot of difference unless you are uning it in extreme cold or extreme hot conditions I would have thought.
I put some info in the video description. It was an air rifle PCP stirrup pump what I used as you need 160PSI. If you need anything else, just drop me a message 🙂
Thank you for the video, I have this nailer and it has lost some pressure as it only fires 90mm ring shank nails half way as it never used to. What is the valve connection that you used? is it possible to get something like that to connect to an air compressor? Any help would be great. Thank you
I think it is a 1/8 BSP male connection, as searching for similar pumps that's pretty much what they said. The pump used was a stirrup pump for a PCP air rifle, but apparently Scott used a high pressure bike pump that goes up to 160psi with an adapter he made from a normal bike style valve to a 1/8 bsp male. Glad you enjoyed the video and found it useful!
Just search ebay for PCP pump. I just saw an VEVOR 3 stage 4500psi stirrup pump for £32 it's the same one I used, and I'm fairly sure its 1/8" BSP coupler you need
I came across this because of my 2nd gen brad nailer which is making the same sound. It appears as if the grinding noise is the chain "gear " mechanism trying to move the already-moved piston into the cylinder to compress the air for a quick release(fire) but can't because there is no pressure to fire it. If I simply add air or nitrogen without disassembly & cleanout of seals it will just happen again. Sounds like I will be tearing mine apart this afternoon. Note: I hope I don't need any internal replacement parts as it appears as if milwaukee doesn't offer any for my 2746-20
You can just fill it up, if it's leaked it will probably do the same again over time I'd suspect. You're probably best off cleaning it all out and re-greasing it. I've also got a brad nailer to look at. I'd suspect it will be pretty much the same as the crown stapler which I also repaired (might be worth checking that video if you haven't seen it).
My nail gun has the exact same problem and I have only had for a year and a half and stupidly didn’t sign up for 3 year warranty, isn’t the tank supposed to be filled with nitrogen and not air?
Yes you are correct. Although air is 78% nitrogen. The reason they use nitrogen is for consistency when driving nails apparently. For example if you were working in extremely cold and extremely hot environments the air would contract or expand slightly. Although everyone that's used air hasn't said they have noticed any difference. I did see some nitrogen filling kits on Ebay for air conditioning but I've not tried using one.
@@ItzMilla Some people suggested to use silicone grease as normal might damage the seals. I just just used regular grease as that's what I had at the time but I probably should have used silicone just in case.
Thanks! I've just been doing a 18ga crown stapler. Pretty much the same problem. Fixed now but needed less pressure than the nail gun as it only has a small cylinder. Video coming soon...
The fitting I used came with the air rifle pump. I believe it's a 1/8" coupling. Don't worry about pressing the centre pin on the valve, the air will force it open when the pressure is greater on the outside compared to the inside.
Great video! I have a question thought. Do you think using compressed air will rust and cause problems long term with the cylinder and piston? Hydrogen is lighter than air and effects the electrochemical kinetics of the metal. not sure what's worse pitting or rust? I guess if the air was clear and dry it shouldn't make a difference. Thoughts?
I can't get mine to take the air. It won't pressurise at all. Does this mean that the valve is buggered? I did use a 1/8 BSP adapter and hooked it up to my air compressor, but it wouldn't pressurise. What would you recommend that I do?
What pressure does your compressor go up to? You need to have 160PSI for it to function correctly. Try pressing the valve centre to see if anything comes out. If it won't pressurise then there must be a leak. Perhaps try filling it and then listen to see if you can hear where there is air escaping? I doubt it will be the valve and more than likely one of the seals. Did you strip it down and clean it all?
My compressor goes up to 180psi, but when I try to pressurise the canister, it stops at 100psi and won't go any higher. The valve definitely holds some pressure as I can release the air by pressing on the valve. Do I need a higher out compressor. The spring is then extra hard to pull out of the canister, hence why I thought that it must still retain air.
Shouldn't my connection depress the Schrader valve to push air into the canister? It isn't long enough, and that's why I thought maybe buying the one used for Hikoki nail guns.
no, no need. I explained in the video description about the opening pressures of Schrader valves as someone said the video was fake due to not pressing the centre pin. The air pressure to open the valve is only a few PSI more than the internal pressure of what is in the cylinder so if the cylinder has 30PSI inside and you try to put 36PSI in, the valve will open regardless. It's there to stop the air coming out 🙂
Hi mr buy it fix it. I have a similar problem with my Milwaukee nail gun. Mine has lost pressure so needs pumping back up again but also the black rubber block inside the cylinder is damaged and virtually obliterated so I need to get a replacement rubber block. Do you know where I would be able to buy one from and what its technical term would be called please ?
Sorry unfortunately not, and I doubt Milwaukee will sell it as a part. If it was me I'd perhaps look at some car parts like a suspension bump stop or something that might be a similar size.
Thank you for making the video it is very helpful I just bought a (pcp 4500 psi) air gun rifle pump and a 1/8 bsp male to male adapter on eBay I just have a question about how did you check to make sure the canister had 160psi? I’m thinking about switching the air rifle pump gauge for a gauge that reads much less psi.
Thank you Angel 👍. That would be the best idea. I didn't bother and if you see the crown stapler video I did I just used the scale on the original meter which is quite hard. I just used 1.5 lines on the scale which would be roughly about right. You could just add a little at a time and test.. at least you cant blow it up that way.
Thanks for this, really helpful. My 18g nailer definitely sounds like it’s lost pressure as it’s making a strange noise and not sinking the brads. I’ll buy a pcp pump and fill it up. Hopefully that’s works! One question. Will it just loose pressure again soon after? Thanks
Do you need a specific 1/8th in air pump attachment cause I’ve seen a video and he said you need a special one with rubber gaskets and a pin to push back that flap deeper in the fill up spot
Rubbish, the Schrader valve will just open with the air pressure. I explain all this in the video description. No its just a basic coupling. Interesting that someone else has done a video, as I was the only person to repair one of these when I uploaded it.
@@BuyitFixithe never repaired it he just took it apart and showed people how to do it but I appreciate this video I just fixed mine today but for some reason it bends the top 1/2” of nail these nails are old so it may be that and also I could only get to 135psi so maybe that’s it but I was having trouble figuring out how much psi was going into the small tank
@@BuyitFixitalso the nails I was using had the small wire holding it together compared to the paper or what looks like paper on your nails. At least 5 year old nails
@@BuyitFixit omg it was the nails it shoots perfect such a great creation I really appreciate this video and I’m going to do more repairs to different Milwaukee nailers and use your videos I really appreciate this content actually learning stuff. And I think I could’ve maybe filled the tank up more but I couldn’t get it to go above 130 psi so I’ll have to find a pump to get it above there and also I heard leaking as I was filling it don’t know if I need a whole new m18 compressor tank and thank you for the speedy response
Another youtuber had to fill it to 200 psi in order to get full power setting to sink nails past flush. His channel is "itll probably work" or something @BuyitFixit
@@BuyitFixit Hello, good morning, where can I get the piece that is placed to put the air, the one you have in the pump is that I can't get it, send me a photo or do you sell them?
Hmm now that's a question... it has been 18 month or so since I did this, so I honestly can't remember. You might be able to pause the video at points and see how they go? I cant remember a specific orientation but the order does matter with the wipers being either side of the main seal if I remember correctly.
After listening to the ramp up time of this gun vs a stock gun, it sounds like the ramp up is a little slower than normal. The Hitachi guns are only filled to 110psi so could 160 be a little high?
Possibly, it does seem rather powerful so you may well be right. It does sink the nails I was using fully and it's not on maximum and it can take longer nails still.
If you used a compressor, the pressure would just equalize. It won't take in more than it's capacity. I used an air rifle stirrup pump and it was roughly 160PSI that I put in it, but was told from someone else that 160PSI is correct. If in doubt, you can always try a lower PSI, and test, then increase in increments until you get the desired power.
Recharging it is simple enough it's when it actually breaks down or a part fails basically some of the more important parts Milwaukee will not sell the part to the general public authorized service personnel only service in themself void warranty
Yes, parts for a lot of Milwaukee tools aren't readily available, and even when they are I've found they tend to sell a full assembly rather than individual components. I repaired a M18 orbital sander which the motor shaft had snapped. You could not buy the motor, but had to buy a whole assembly with bearings, belts, cogs etc which was £89 and a new sander was only £99! I managed to find almost the exact motor on Aliexpress and repaired it for £9.
Great video. Learned a lot, I also repaired my nail gun. But I'm having trouble finding a way to put air back in the tank. Can you give me some insight?
I don't think there is a way to adjust the timing. The sensor just measures when the piston wound back fully. There should be some links in the video description of stuff that I used to refill the tank.
There's a solenoid that release it (fires the gun). I'd be very careful doing that though. What I did was empty the remaining gas and stripped everything down (as in the video) then there is no issue and probably a lot sater. If it still has gas it, I'd watch your fingers if you release the pin manually. Perhaps move it with a screwdriver or something so your hand's are well out of the way. The little solenoid is silver and has a little lever on it that gets pulled in and releases the firing pin.
The canister is used like an air spring. The gas in the cylinder is compressed and gets compressed even more when the motor winds the ratchet back. When you press the trigger the firing solenoid gets energised and releases the firing pin / ratchet which then shoots forward. If there is a slight leak the cylinder loses pressure over time resulting in a kind of farting noise when you try to fire the gun.
Hi @BuyitFixit, my 21 degree framing nailer is still not working i took it apart and cleaned and greased everything and when i put it back together and reset the firing pin it did the initial reset sound then it started clicking and lights started blinking, any idea what it would be?
Before i took it apart the gun would sink a nail completely and then start clicking and i would reset the firing pin and and it would sink a nail and start clicking again, been trying to find any information available to find the problem but i can seem to find it, i think you had mentioned the hall effect sensor is another common problem but how can i diagnose it?
Sorry for the late reply. The fix here is if it's not sinking nails. It sounds indeed like a hall effect or sensor problem. The gun should detect that it's "re-wound" the firing pin. There is a sensor that detects that. It sounds like either the sensor has failed / or possibly a broken wire or something. There should be a couple of wires, I think one is the pressure switch that detects when the gun is pressed against an object, and the other is a sensor that detects when the firing pin is back to the home position.
@@BuyitFixit yeah i put the battery on while i had the cover off and i checked everything was working and i took off the 2 screws that hold that sensor in place and removed the sensor and it responded the same as when the sensor was on so i bought the the whole electrical assembly on ebay and hopefully it works
You're the only video that actually breaks them down but all the articles I'm reading say it's nitrogen filled? Wouldnt running just o2 be weaker? Paslode runs nitrogen cans. Any ideas?
It's not O2 as the air is 78% nitrogen. They use pure nitrogen because it is supposed to be less susceptible to temperature differences and less likely to cause corrosion. Apart from that it will work fine. You can get nitrogen refilling kits on Ebay for air conditioners which should work too. Works fine with air also 😂😂
Possibly, it's something I've not tried. I haven't needed to fill it since making the video (and used it a few days back), although I don't use it a lot.
It's all in the video description. It's a 1/8" brass coupling. It doesn't need to press the valve in or anything as the air pressure will open the valve anyway.
Great! Glad it helped. I've bought a broken 2nd fix nailer and a stapler to repair. I haven't looked at them yet but I imagine they are all very similar.
Nice fix. How has it been since you fixed it? Don't they come filled with nitrogen from the factory? I wonder if changing to air causes any issues down the road
Been fine although I don't use it on a regular basis. Yes nitrogen and it's used because it doesn't expand and contract as much as air with temperature variations apparently.
At the end when it was reassembled,what the first issue was that the firing rod was extended,if anyone else runs into this,just remove nails and dry fire it it resets the rod position :) great video btw!!
Thanks Matt g, yes totally correct at the dry fire resetting the mechanism 👍
hi where can i get the schematics of this tool? i need to reassemble the gearbox
There are no schematics. Most of the tools use a planetary gearbox arrangement where there are 3 cogs in the centre where the motor shaft goes with an outer cog, this then usually connects to another similar set (I disassembled a drill some time ago)
@@BuyitFixit oh thank you ive been trying to find them. i guess ill have to work it out. is there any comparable drill thats the same?
I'm not 100% mate, I just remember it looked a very similar arrangement. Probably to get more torque to wind the piston back.
Stripped mine down this morning and I can’t thank you enough for this video.. worked out 100%

Glad you found it useful and good luck with your repair!
Did you fix it?
Thank you for the video. Concise, complete, and dense with data.
Thanks 🙂👍
Think mines coming apart this weekend. The extreme cold affects the tools performance, doesn't sink nails as well. Think mine might just need a little air to top it up.

They should put in a shredder valve with an dust plug
They do. It's just not accessible without taking the tool apart. The silver metal piece is the dust cap, and under that where I screw the filler adapter is the shrader valve. I don't think they expect the average user to repair these.
@@BuyitFixit they should add a rubber cap to make it accessible.
Yeah. I don't think they expect the average user to service or repair it themselves
great video, my nail gun has been broken for couple of days
tomorrow i am willing to fix it after watching the video
Nice, good luck. Just be careful and let any air out of the cylinder before disassembling the cylinder.

Thanks for this. My finish gun was doing the same, sent it away and was told it couldn't be fixed. Now I have the gun going again l 👍
Brilliant news Kevin! I'm really pleased that you managed to get your gun working again. The finishing gun needs less PSI than this one. I think it was around 90 to 110 PSI if I remember.
Have you had any issues with using O2 to refill it rather than nitrogen?
@adamandlorraine O2? He used air, which is 78% Nitrogen...not pure oxygen

Would there be room to leave a shrader valve on the tank to make future recharges easierm
I'm not sure if there would be enough room, good idea though 👍
There is a simpler way, turn the bell 90° and drill a 15mm hole in the gun shell, opposite the inscriptions, to put the valve on the outside. This way it is possible to repressurize at any time without disassembling the housing.

Where can I buy that pump or a fitting to fill the canister?
Amazing video! Our team runs about 7 of these guns and we always have one out of commission getting serviced but by the looks it’s super easy to give it a quick re-gas
Thanks 👍Check the video description, I put some more information in there 🙂
Nice job. Im going to the basement and fix mine right now!
Nice 👍Hopefully you managed to get it working 🙂
Hi,
Found your vids really helpful.
It's hard to have these filled with nitrogen as I'm not sure if there is a maximum psi lable on cylinder. So tyre or diving shops are reluctant to touch.
Theses no info around to give maximum psi that you kindly supplied.
So air pump it is. Did you use some kind of regulator on that pump. As it's hard to get an accurate 160 psi with a gauge that goes up into the 4000's
Thanks 👍. I was told around 160psi, but s viewer recently said he thought it was too much and around 120psi was better. You can always start lower and add a few more pumps you think it's not powerful enough. Yes it was hard to gauge on the gauge as you said due to the scale.
Do you think the narrow 1/4 crown stapler gun m18 also works the same as these ? So how often those this maintenance has to been done ? And one big quest does Milwaukee warranty cover this service of the refill of air or there’s is a cost even the 3/5 years warranty , so you used just a compressor to fill up no special gas like nitrogen? I saw the ryobi version brush but they use the same motor to sort of compres the air in like a chamber no need of compressor which is good and bad as idont know how deep can the brad or staples can penetrate the material. But I learn a lot just by watching you video
Thank you. I've also bought a broken 2nd fix nail gun and a crown stapler to do videos on, so I guess we'll find out soon! I've been busy with other things the last week so haven't had a chance to do videos lately. Stay tuned as there's more coming!
What size the the air fitting you have can’t seem to find one
Everything is in the video description 👍
You fix all the milwaukee trouble the super saw all i dont understand how you do but you do it ! My cir saw rear handle did the same as the supersawall video... also my fraiming nailer have do this also
Glad I could help
Great video. Gun only lasted one big job. I'll give this a go. Thank you!
Thanks 👍Many people have managed to repair their nail guns from my video, so I hope you manage too!
You reckon an ATS branch would fill the canister with their Nitrogen tyre inflation kit ?? perhaps they're limited to too low pressure as tyres aren't inflate to anything like 160psi would probably need some sort of adapter too
I did see nitrogen kits on Ebay for aircon. They might have enough pressure but I've not tried one. I personally would just fill it with air it's 80% Nitrogen anyway.
Great video mate!
Do you have a make or link for the pcp pump, and did it come with the exact adapter?
Check the video description I did put some more info in there. Search on Amazon or such for stirrup pump you should find one the same as the one I used or very similar.
Fantastic...still seaching for that threaded adopter to fit into cylinder..i hv m12 inflator..
What king of converter do i need
Any help
I think I've already said in the video description, and in another comment. I can't remember off hand but think it was 1/8 bsp?
Can you send me the link of the valve I have two damaged gun like this and with your video I think I can fix them
The valve I used actually came with the stirrup pump. An air gun shop should be able to help as it's a standard fitting. I think its 1/8 BSP.
@@BuyitFixit thank you!!
No problem. Good luck with your repair!
@@BuyitFixit thank you for the video👍👍
Hi it's very nice video but many of the oil and grease like wd40 are not compatible with the rubber which will make them expand...
Tjanks 👍Yes, I should have used a silicone grease. Unfortunately I didn't have any at the time, but I know for next time. Thanks for commenting 👍
@@BuyitFixit It seems I made a mistake and put some lithium grease into that chain wheel, don't know what happened in the future. Do you know what's the size of the inflator threat? Thank you so much
@@狮子子 as far as I know its 1/8" I used an air rifle stirrup pump and the adapter was just a straight through coupler. The air pressure will open the valve.
This is a great video thanks, I tried pumping it up with a bike pump with a adapter I managed to sort but I can’t get any pressure in the gun at all can you help thanks
Unfortunately I dont think a bike pump is up to the job. You need about 160 PSI and most bike wheels are around 30 PSI which is why I used an air rifle pump.
@@BuyitFixit I have got a small bike suspension pump which goes up to 200psi but the won’t work either, iv ordered a air rifle pump now so fingers crossed that will work thanks
Have you stripped it down like I did in the video? The only thing I can think that would stop it holding a charge would be worn seals or a cracked or worn barrel. You should be able to hear the air escaping in either case.
@@BuyitFixit yes it’s all been stripped and cleaned and no broken seals, does the air valve pin in the middle have to be pushed in to allow air in as the adapter I have isn’t long enough to push the pin in thanks
You can get away with not pushing the pin in if the pressure is great enough as it will just force the valve open.
Just regular air to 160Psi?? Or is another gas?
Originally they are supposed to be filled with Nitrogen (apparently to stop thermal variations in pressure) but seeing as air is 80% Nitrogen anyway I doubt you would notice any real difference unless you were working in Antarctica and then going to the Sahara!
@@BuyitFixit Costco fills their tires with nitrogen. Just don’t believe they reach 160psi
Normal car tyres wouldn't need that sort of pressure, this is a small cylinder with a piston that's hammering a nail into quite solid wood hence the high pressure 🙂
@@BuyitFixit would using WD40 hurt the seal O rings?
Perhaps, I should have probably used silicone grease, but I do make mistakes and I'm no expert 🙂
Great video. I have one just like this but as well as the power dropping (probably lost gas pressure) it's just stopped firing almost entirely. It fires very occasionally after holding the trigger for ages and waggling it around a fair bit. Any ideas why?
Thanks Phil 👍from what you describe it could be a bad trigger switch? Or possibly the switch that senses when it is pressed against an object.
@@BuyitFixit yes, I'm afraid that might be the problem. Funny how the faults pile up with things like this! Going to try a teardown and clean later so will hopefully find out what's going on. I wish I had an air rifle pump like yours though!
So the trigger switch works, but gets misaligned easily. I think it's a bit of a design flaw that they overcome with hot glue in the factory. Managed to open up the gas cylinder to find it full of condensation - a sure sign that someone has already tried to regas it themselves. Got it repressurised but not high enough. Trying again later.
Let me know how it goes Phil 👍
@@BuyitFixit got it pressurised up to 160psi (hard work with a mini bike pump!) and it seems to be back up to full power. Very pleased. I just wish the tool had a maintenance mode like the Hikoki/Metabo nailers so the firing rod extends all the way out for resgassing. Annoying having to dismantle it each time.
I just wondering what kind of grease you used or should I use?
If I was doing it again I'd probably use silicone grease.
@BuyItFixIt where did you find the psi setting for the different nailers i have a M18 FUEL 16GA STRAIGHT FINISH NAILER 2741-20 and i believe this is the issue i just am not sure what psi to use. Was there somewhere you found this information?
There's no definitive information as such, however you can start low then increase the pressure until it works correctly. I spoke to someone else who had repaired a few of these at the time, and he said around 160psi for this gun and around 120psi for the smaller guns.
thanks for your video, i have just re gassed my Milwaukee finishing gun
Well Done 🙂I'm glad you found it useful 👍
They usually fill them with Nitrogen but since air contains about 78% Nitrogen I guess that will work fine. What I wonder is are the two sealing rings symmetrical or do they have a specific orientation just like an Automotive Piston rings?
I'm not sure about the rings orientation, but yes agree with the 78% nitrogen. When I looked into it at the time it said somewhere that it was to stop variations in pressure due to different temperatures which probably wouldn't make a lot of difference unless you are uning it in extreme cold or extreme hot conditions I would have thought.
I have a couple of questions: where did get the hose charger for your Milwaukee nail gun and what model is that hose so I can get it?
I put some info in the video description. It was an air rifle PCP stirrup pump what I used as you need 160PSI. If you need anything else, just drop me a message 🙂
I can't seem to find the pump you have do you have more info on it
What kind of air chuck did you use to re charge the solenoid? I can’t seem to find one that fits
Did you check the video description? I put a lot of info in there.
Thank you for the video, I have this nailer and it has lost some pressure as it only fires 90mm ring shank nails half way as it never used to.
What is the valve connection that you used? is it possible to get something like that to connect to an air compressor? Any help would be great. Thank you
I think it is a 1/8 BSP male connection, as searching for similar pumps that's pretty much what they said.
The pump used was a stirrup pump for a PCP air rifle, but apparently Scott used a high pressure bike pump that goes up to 160psi with an adapter he made from a normal bike style valve to a 1/8 bsp male.
Glad you enjoyed the video and found it useful!
I'm struggling to find something I can connect to my dewalt inflator, any suggestions on what fitting to buy?
Someone said it's 1/8 BSP but I'm not 100%, as I had an adapter that fit that came with my pump.
Do you know which adaptor and pump it is please? Kinda going crazy finding it.
Just search ebay for PCP pump. I just saw an VEVOR 3 stage 4500psi stirrup pump for £32 it's the same one I used, and I'm fairly sure its 1/8" BSP coupler you need
I came across this because of my 2nd gen brad nailer which is making the same sound.
It appears as if the grinding noise is the chain "gear " mechanism trying to move the already-moved piston into the cylinder to compress the air for a quick release(fire) but can't because there is no pressure to fire it.
If I simply add air or nitrogen without disassembly & cleanout of seals it will just happen again.
Sounds like I will be tearing mine apart this afternoon.
Note: I hope I don't need any internal replacement parts as it appears as if milwaukee doesn't offer any for my 2746-20
You can just fill it up, if it's leaked it will probably do the same again over time I'd suspect. You're probably best off cleaning it all out and re-greasing it. I've also got a brad nailer to look at. I'd suspect it will be pretty much the same as the crown stapler which I also repaired (might be worth checking that video if you haven't seen it).
My nail gun has the exact same problem and I have only had for a year and a half and stupidly didn’t sign up for 3 year warranty, isn’t the tank supposed to be filled with nitrogen and not air?
Yes you are correct. Although air is 78% nitrogen. The reason they use nitrogen is for consistency when driving nails apparently. For example if you were working in extremely cold and extremely hot environments the air would contract or expand slightly. Although everyone that's used air hasn't said they have noticed any difference. I did see some nitrogen filling kits on Ebay for air conditioning but I've not tried using one.
@@BuyitFixit okay thanks mate, do you know what size valve I need for it to fit the cylinder?
Yes, and I've answered it loads of times in the comments, and also put all the info in the video description :)
@@BuyitFixitsorry mate one last question, what type of grease did you use? Does it matter? Plan on fixing mine today
@@ItzMilla Some people suggested to use silicone grease as normal might damage the seals. I just just used regular grease as that's what I had at the time but I probably should have used silicone just in case.
Nice fix, got yourself a cheap nail gun there! I just bought one of these a few weeks ago so hopefully will be some time before it needs repairing.
Thanks! I've just been doing a 18ga crown stapler. Pretty much the same problem. Fixed now but needed less pressure than the nail gun as it only has a small cylinder. Video coming soon...
Hello what is that pipe cleaner tool you used to clean inside the can? Looks to work a ton better than just those circular brushes
Hi I'm not sure what tool you mean? I just used some cleaning wipes if I remember and some WD40.
Hi is there any chance you could link the air adapter you used in this video. Thank you.
Hi Brandon, sorry it came with the pump. I think it's a 1/8 BSP fitting
Hey mr Buy it Fix it, great vid, but am I able to fill this up with a compressor cuz that’s all I got?
Thanks. I'm not sure what PSI your compressor goes up to? I filled the gun up to 160psi. You might get away with less..
How many pounds of air pressure did you give with the pump?
Should be in the video description, it was around 160PSI if I remember, but you can add less, and check the power, then add more if needed.
Thank you for the video, made for a much easier fix!
Glad it helped!
Hello, where can I get the adapter to put air in it?
The one I used came with the pump. I'd try ebay or a hardware store perhaps. It's 1/8"
@@BuyitFixit You can send us photos or a video of what it looks like so we can look for it.
Wonder how long air lasts versus nitrogen
I'd say no different, depends on how leaky your gun is. Air is 80% Nitrogen anyway.
Can you tell me the size of the Airbrush?
I searched a lot but I didn't find it. I live in Germany, and maybe it's an American size.
I'm not sure what part you mean, unfortunately Milwaukee don't sell parts for these.
Can you send me a link to the air blower? I looked for it but couldn't find it
@@BuyitFixit
Hi great video where can I get the fitting to fill the air?
The fitting I used came with the air rifle pump. I believe it's a 1/8" coupling. Don't worry about pressing the centre pin on the valve, the air will force it open when the pressure is greater on the outside compared to the inside.
Thanks greatly appreciated how much pressure do I put in?
It's all in the video description mate. The coupling size, pressure etc. 160psi
Sorry I have another question
Is it safe to put air in with my shop compressor
Can't see any reason why not, if it will go up to 160PSI.
Great video! I have a question thought. Do you think using compressed air will rust and cause problems long term with the cylinder and piston? Hydrogen is lighter than air and effects the electrochemical kinetics of the metal. not sure what's worse pitting or rust? I guess if the air was clear and dry it shouldn't make a difference. Thoughts?
Yes if the air had moisture in it then it may over time cause some oxidation of the aluminium, Hydrogen is explosive so I wouldn't fancy that!
If I had the setup, I would have used nitrogen.
Glad you did not cleaned the gun on the kitchen table.😂😂🤣🤣 Great repair mate.
Thanks 👍yes the blue mat would have been the black mat 😂😂😂
Fantastic fix again least it was just mechanical this time
Yes was fairly straightforward once I knew what I was doing. Thank you for your support!
I can't get mine to take the air. It won't pressurise at all.
Does this mean that the valve is buggered? I did use a 1/8 BSP adapter and hooked it up to my air compressor, but it wouldn't pressurise.
What would you recommend that I do?
What pressure does your compressor go up to? You need to have 160PSI for it to function correctly. Try pressing the valve centre to see if anything comes out. If it won't pressurise then there must be a leak. Perhaps try filling it and then listen to see if you can hear where there is air escaping? I doubt it will be the valve and more than likely one of the seals. Did you strip it down and clean it all?
My compressor goes up to 180psi, but when I try to pressurise the canister, it stops at 100psi and won't go any higher.
The valve definitely holds some pressure as I can release the air by pressing on the valve. Do I need a higher out compressor.
The spring is then extra hard to pull out of the canister, hence why I thought that it must still retain air.
Yes, I did everything that you have done in your excellent video, I really do appreciate it.
Shouldn't my connection depress the Schrader valve to push air into the canister?
It isn't long enough, and that's why I thought maybe buying the one used for Hikoki nail guns.
no, no need. I explained in the video description about the opening pressures of Schrader valves as someone said the video was fake due to not pressing the centre pin. The air pressure to open the valve is only a few PSI more than the internal pressure of what is in the cylinder so if the cylinder has 30PSI inside and you try to put 36PSI in, the valve will open regardless. It's there to stop the air coming out 🙂
Hi mr buy it fix it. I have a similar problem with my Milwaukee nail gun. Mine has lost pressure so needs pumping back up again but also the black rubber block inside the cylinder is damaged and virtually obliterated so I need to get a replacement rubber block. Do you know where I would be able to buy one from and what its technical term would be called please ?
Sorry unfortunately not, and I doubt Milwaukee will sell it as a part. If it was me I'd perhaps look at some car parts like a suspension bump stop or something that might be a similar size.
You rock you got the fix😊
@@Mason_ater3 Thanks 👍
Thank you for making the video it is very helpful I just bought a (pcp 4500 psi) air gun rifle pump and a 1/8 bsp male to male adapter on eBay I just have a question about how did you check to make sure the canister had 160psi? I’m thinking about switching the air rifle pump gauge for a gauge that reads much less psi.
Thank you Angel 👍. That would be the best idea. I didn't bother and if you see the crown stapler video I did I just used the scale on the original meter which is quite hard. I just used 1.5 lines on the scale which would be roughly about right. You could just add a little at a time and test.. at least you cant blow it up that way.
Thanks for this, really helpful. My 18g nailer definitely sounds like it’s lost pressure as it’s making a strange noise and not sinking the brads.
I’ll buy a pcp pump and fill it up. Hopefully that’s works! One question. Will it just loose pressure again soon after?
Thanks
Mine hasn't. Still working great!
@@BuyitFixit One more thing do you have to make sure that the piston is fully open at the canister before you apply air pressure?
@@AngelVega-kx7lg not sure what you mean but the firing pin needs to be fully out like it has just fired.
Do you need a specific 1/8th in air pump attachment cause I’ve seen a video and he said you need a special one with rubber gaskets and a pin to push back that flap deeper in the fill up spot
Rubbish, the Schrader valve will just open with the air pressure. I explain all this in the video description. No its just a basic coupling. Interesting that someone else has done a video, as I was the only person to repair one of these when I uploaded it.
@@BuyitFixithe never repaired it he just took it apart and showed people how to do it but I appreciate this video I just fixed mine today but for some reason it bends the top 1/2” of nail these nails are old so it may be that and also I could only get to 135psi so maybe that’s it but I was having trouble figuring out how much psi was going into the small tank
@@BuyitFixitalso the nails I was using had the small wire holding it together compared to the paper or what looks like paper on your nails. At least 5 year old nails
That could possibly be it. I'd try some fresh nails to rule it out. Glad you managed to fix it. Well done 👍
@@BuyitFixit omg it was the nails it shoots perfect such a great creation I really appreciate this video and I’m going to do more repairs to different Milwaukee nailers and use your videos I really appreciate this content actually learning stuff. And I think I could’ve maybe filled the tank up more but I couldn’t get it to go above 130 psi so I’ll have to find a pump to get it above there and also I heard leaking as I was filling it don’t know if I need a whole new m18 compressor tank and thank you for the speedy response
Everyone: when you open the framing nailer, it says on the canister that it’s 102psi. Don’t overinflate it to a level it’s not designed for. 1-0-2
I'm sure there was nothing written on the canister on this one. Are you sure 102psi makes it work correctly and not underpowered?
Another youtuber had to fill it to 200 psi in order to get full power setting to sink nails past flush. His channel is "itll probably work" or something @BuyitFixit
@@BuyitFixit Hello, good morning, where can I get the piece that is placed to put the air, the one you have in the pump is that I can't get it, send me a photo or do you sell them?
what kind of connector does the pump that spins into the milwaukee reservoir have?
Check the video description 👍
Is it a 1/8th male to male coupling you need
What kind of insert you using? I was thinking to use the ac cans, but can't find a proper adapter
Hi Jack, I've been asked this a lot. Check out the video description which has all the details :)
What orientation do the piston rings go? I pulled mine off to clean and didnt remember the roatation. My rings have little indents in them
Hmm now that's a question... it has been 18 month or so since I did this, so I honestly can't remember. You might be able to pause the video at points and see how they go? I cant remember a specific orientation but the order does matter with the wipers being either side of the main seal if I remember correctly.
Is there a link for the hand pump you have to regas it from Amazon? Can’t seem to find this kind of pump in any store I’ve been to
I'm not sure if you are UK or US, so just search PCP Stirrup Pump. They are used for air rifles.
After listening to the ramp up time of this gun vs a stock gun, it sounds like the ramp up is a little slower than normal. The Hitachi guns are only filled to 110psi so could 160 be a little high?
Possibly, it does seem rather powerful so you may well be right. It does sink the nails I was using fully and it's not on maximum and it can take longer nails still.
160 psi so let your compressor fill up at 160 and then let all the 160 air in it? Or just some
If you used a compressor, the pressure would just equalize. It won't take in more than it's capacity. I used an air rifle stirrup pump and it was roughly 160PSI that I put in it, but was told from someone else that 160PSI is correct. If in doubt, you can always try a lower PSI, and test, then increase in increments until you get the desired power.
Recharging it is simple enough it's when it actually breaks down or a part fails basically some of the more important parts Milwaukee will not sell the part to the general public authorized service personnel only service in themself void warranty
Yes, parts for a lot of Milwaukee tools aren't readily available, and even when they are I've found they tend to sell a full assembly rather than individual components. I repaired a M18 orbital sander which the motor shaft had snapped. You could not buy the motor, but had to buy a whole assembly with bearings, belts, cogs etc which was £89 and a new sander was only £99! I managed to find almost the exact motor on Aliexpress and repaired it for £9.
Where did you buy the hand pump and tip? Need to add air to gun as well
I just got it off Ebay original to fill an air rifle. It actually came with the 1/8" bsp adapter which I used.
Great video. Learned a lot, I also repaired my nail gun. But I'm having trouble finding a way to put air back in the tank. Can you give me some insight?
Also, what is the best way to check the timing on the chain/ firing pin?
I don't think there is a way to adjust the timing. The sensor just measures when the piston wound back fully. There should be some links in the video description of stuff that I used to refill the tank.
@@BuyitFixit thank you. I will check it out.
Hey hope all is well, I'm still trying to find the correct fitting. Do I need a bspt or bspp fitting?
Not 100% I'm pretty sure it was bsp.
Hola disculpa donde puedo encontrar el adaptador para bobear el aire
Amazon 1/8" coupler
How do you get the firing pin to stay down so you can fill it with air?
There's a solenoid that release it (fires the gun). I'd be very careful doing that though. What I did was empty the remaining gas and stripped everything down (as in the video) then there is no issue and probably a lot sater. If it still has gas it, I'd watch your fingers if you release the pin manually. Perhaps move it with a screwdriver or something so your hand's are well out of the way. The little solenoid is silver and has a little lever on it that gets pulled in and releases the firing pin.
Great Job!!!
Thanks 👍
Is it required to fill the canister before it will fire? I don’t have that pump
The canister is used like an air spring. The gas in the cylinder is compressed and gets compressed even more when the motor winds the ratchet back. When you press the trigger the firing solenoid gets energised and releases the firing pin / ratchet which then shoots forward. If there is a slight leak the cylinder loses pressure over time resulting in a kind of farting noise when you try to fire the gun.
I love the noises when disassembling and reassembling... sounds like disassembling a rifle. (From what I've heard in the movies 😆) Great video 👍🏻
Thanks 👍🙂
Hi @BuyitFixit, my 21 degree framing nailer is still not working i took it apart and cleaned and greased everything and when i put it back together and reset the firing pin it did the initial reset sound then it started clicking and lights started blinking, any idea what it would be?
Before i took it apart the gun would sink a nail completely and then start clicking and i would reset the firing pin and and it would sink a nail and start clicking again, been trying to find any information available to find the problem but i can seem to find it, i think you had mentioned the hall effect sensor is another common problem but how can i diagnose it?
Sorry for the late reply. The fix here is if it's not sinking nails. It sounds indeed like a hall effect or sensor problem. The gun should detect that it's "re-wound" the firing pin. There is a sensor that detects that. It sounds like either the sensor has failed / or possibly a broken wire or something. There should be a couple of wires, I think one is the pressure switch that detects when the gun is pressed against an object, and the other is a sensor that detects when the firing pin is back to the home position.
@@BuyitFixit yeah i put the battery on while i had the cover off and i checked everything was working and i took off the 2 screws that hold that sensor in place and removed the sensor and it responded the same as when the sensor was on so i bought the the whole electrical assembly on ebay and hopefully it works
@leonidesocegueda9718 how'd it go? Did it work?
You're the only video that actually breaks them down but all the articles I'm reading say it's nitrogen filled? Wouldnt running just o2 be weaker? Paslode runs nitrogen cans. Any ideas?
It's not O2 as the air is 78% nitrogen. They use pure nitrogen because it is supposed to be less susceptible to temperature differences and less likely to cause corrosion. Apart from that it will work fine. You can get nitrogen refilling kits on Ebay for air conditioners which should work too. Works fine with air also 😂😂
Can you send me a link to the air blower? I looked for it but couldn't find it
Search "3 stage stirrup pump" 👍
@BuyitFixit this should be a pinned comment, i would've never found it unless lol
I skipped through the video. What exactly was the problem -- not enough air pressure in the tank? Thanks!
Yes, pretty much exactly that. I also cleaned the seals and re-greased everything although I should have probably used silicone grease.
enjoying the videos!
Thank you! Really appriciate you letting me know!
So can I fill the canister back up with my m18 inflator?
I'm not sure what pressure output the M18 inflator goes up to. You need around 160 PSI
What an amazing tool
Yes they are pretty powerful!
Good job brother!! I have one doing the same. Fixing to tear into it. Very educational!!! I'll be watching you religiously.😁
Thanks Tim 👍
How on earth did you get that much psi from a bike pump ?
It's an air rifle PCP pump mate.
I can’t seem to find this adapter to fill the tank do you have a link I could follow?
This is a link to one pretty much the same as I used. www.amazon.co.uk/sourcing-map-Fitting-Nipple-Connector/dp/B07KS3G1BK
Is the nailer still working?
Not used it for a while but I'm currently in the shed and just tried it. Yep. Still perfect 👍
Couldn't you just rotate the cylinder an extra 90°and drill a hole in the cover for the refill port?
Possibly, it's something I've not tried. I haven't needed to fill it since making the video (and used it a few days back), although I don't use it a lot.
What is the connection to fill the air up?
It's all in the video description. It's a 1/8" brass coupling. It doesn't need to press the valve in or anything as the air pressure will open the valve anyway.
What brand is your pump?
I'm not sure mate, I bought it years ago. It was just a cheap one I think it was around £30 or so at the time.
Thanks for your video it helped me solve and fix my problem I had with my milwaukee gen2 18gauge brad nailer.
Great! Glad it helped. I've bought a broken 2nd fix nailer and a stapler to repair. I haven't looked at them yet but I imagine they are all very similar.
How much pressure did you add in the brad nailer vs the framing?
Man! Thank you so much to show this up, now I'm going to get my nail gun back
You're welcome 👍👍
Nice fix. How has it been since you fixed it? Don't they come filled with nitrogen from the factory? I wonder if changing to air causes any issues down the road
Been fine although I don't use it on a regular basis. Yes nitrogen and it's used because it doesn't expand and contract as much as air with temperature variations apparently.
@@BuyitFixit thank you. Very helpful
Regular compressed air will not last as long as nitrogen, you have the same problems sooner than later.
Why wouldn't it last as long? Air is 80% nitrogen anyway.
