How to fix a Milwaukee nail gun

- In this video we are fixing a Milwaukee nail gun.
The nail gun just spurts and makes a farting type noise and does not sink nails.
I show how to disassemble the nail gun, and repair it.
The fitting to fill I believe is a 1/8" BSP male, and you need a pump capable of providing around 160psi fill pressure.
I had a comment that the method used would not work because the centre pin wasn't pressed on the valve.
There is no need to have anything press the centre pin of the Schrader valve, as they have an "opening pressure". They are a one way valve designed to keep the air inside the container.
If the pressure of the air being pumped in is greater than the valve opening pressure + pressure inside the container already then the valve will allow air to flow into the container.
If you search "schrader opening pressure" on google for instance you will see the specifications for different valves.
Here is an example:
Product Code: 015660113 / 1566T.
Opening Pressure: 0.2 - 4PSI
Working Pressure: 15 - 150PSI
As you can see, the opening pressure really isn't that much, the working pressure is what the valve is meant to hold inside the container.

Wow! That is amazing can't get over the power that nail gun has. Thanks for another great video
Yes they are quite powerful! Thank you for your kind comment.
Stripped mine down this morning and I can’t thank you enough for this video.. worked out 100%
Nice! Well done on fixing your nail gun 🙂👍👍
I bought this nail gun as we were planning to renew all the fencing in our back garden. As this involved 19 double slatted fence panels, 10 of which needed to be cut down in size, we knew there would be a need for a great th-cam.com/users/postUgkxHQsUrwNr5GQrnx9V4xDdUr56qxwuiBHt deal of re-stapling the wooden slats to the wooden framework. Each alteration required the re-stapling of 62 wooden slats with double staples. Prior to starting the work we ordered sufficient additional staples as per the instructions with the gun.The gun performed fantastically throughout the entire project with no jams of misfires. The adjustable power was excellent allowing the staples to be fired into the 8mm slats to the correct depth. For the price paid this was a bargain and it proved itself to be so reliable and versatile making an arduous task much quicker and professional. I cannot recommend this product highly enough and it will be used on many other projects in the future.
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.
Thank you for the video. Concise, complete, and dense with data.
Thanks 🙂👍
Much appreciated, I have the same issue with my m18 framing nailer and now feel confident in fixing it
Glad you found it useful and good luck with your repair!
Did you fix it?
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.
No problem. I'm glad you found it useful and were able to fix you gun. Well done 👍👍
Man! Thank you so much to show this up, now I'm going to get my nail gun back
You're welcome 👍👍
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.
Thanks Allen, a lot of people have repaired their guns after watching.
My gun broke down yesterday after 1 year of heavy work, I got a new one but , Im going to try to fix it, thanks for this video.!
No problem Eddy. Hopefully you can fix your gun!
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!!!
No problem Jim. I'm glad you found it useful! I've repaired a fair few Milwaukee items so far!
Did you get it working again?
@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
Thank you for the video, made for a much easier fix!
Glad it helped!
Thanks for the video. I just bought one of those used with the same issue
No problem👍. Hopefully you can now fix it 🙂
@@BuyitFixit was hoping it just took a fall and need a mag put on it
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
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!
enjoying the videos!
Thank you! Really appriciate you letting me know!
What an amazing tool
Yes they are pretty powerful!
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
Good job brother!! I have one doing the same. Fixing to tear into it. Very educational!!! I'll be watching you religiously.😁
Thanks Tim 👍
Worked like a charm for my 18GA finishing nailer. Thank you
Glad the video was helpful to you! Well done on repairing your nailer!
Different set up alot easier than the framing gun
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.
Did you put 160 psi in the 18g?
@@strizzy239 no, that would be too high. Like two pumps
Sehr hilfreiches Video. Vielen Dank!
Du bist herzlich Willkommen!
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.
Thanks 👍 Yes shame the Milwaukee don't have an external refilling port.
senco is the best one
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...
Nice stuff - subscribed!
Awesome, thank you!
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?
Great Job!!!
Thanks 👍
I love the noises when disassembling and reassembling... sounds like disassembling a rifle. (From what I've heard in the movies 😆) Great video 👍🏻
Thanks 👍🙂
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!
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€.
👍👍👍👍🙂
thanks for your video, i have just re gassed my Milwaukee finishing gun
Well Done 🙂I'm glad you found it useful 👍
well done!
Thanks 👍
Great thing to repair. Great equipment. Yea quite the mess lol.nice cleaning
Thanks. Yes a bit messy. I've got a crown stapler and a 2nd fix nailer to look at soon.
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.
Yes, sounds about right. Best of luck 👍
Nice !!
Thanks!
My 15 gauge 2839-20 sounded like this one, went to take it apart and i dont have the Torx bit with the hole on it. 40 miles to nearest home depot lol
Damn that sucks. Yeah security torx are the one with the hole. Amazon?
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 😂😂😂
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.
Thanks Greg.
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
Super dank je wel
graag gedaan!
@@BuyitFixit 😅 dank je wel...
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!
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?
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!
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.
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.
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 😂😂
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 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.
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.
What size the the air fitting you have can’t seem to find one
Everything is in the video description 👍
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 👍
These sure have come a long way. Back when i was a sparky in the 90's, the fancy home builders had cordless nail guns that took a gas cylinder and had spark igniters. They fired the nails in to the framing with a really loud report and a venting of gas. I thought THOSE were cool.
I've never used a gas ignition one, but I'm quite impressed with the power of this thing. I did get a bit of a shock when I first used this one as it is quite loud too 😂😂😂
Thanks for the tear down video. I think you would need Nitrogen to fill up the Milwaukee tank not direct air?
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.
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.
what kind of connector does the pump that spins into the milwaukee reservoir have?
Check the video description 👍
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 :)
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.
@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.
Спасибо .ваше видео очень мне помогло в решении моей проблемы.
Спасибо krovlyaqqq, вам очень рады!
@@BuyitFixit 160psi это слишком большое давление.я поставил на насос pcp более точный манометр.
Спасибо, это было давление, которое кто-то другой рекомендовал. Тот, который я починил, не работал, когда я его получил, поэтому я не уверен, каковы они изначально, когда стреляют.
@@BuyitFixit я сравнивал с новым и по нему выставлял
На балоне написано 105 psi это для тех кто хочет сделать как с завода я ставил 120psi
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 🙂
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.
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.
Hi mate where do you get the valve connection from to get the pressure up. Dimensions also please 👍
Hi, I already put the dimensions in the description 1/8 bsp male, as someone else had asked also. You should be able to get one off ebay or amazon I'd think. Be aware you need to have about 160psi with the piston fully out before it retracts.
Hola disculpa donde puedo encontrar el adaptador para bobear el aire
Amazon 1/8" coupler
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..
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.
Finally got to fixing my broken gun after watching this video. The problem I got is my rubber block (from 5:55) is busted. Can’t find the part anywhere to buy. Any idea where I could get it? Thanks
Unfortunately not. I don't think Milwaukee sell many parts if any for these guns. If I was in the same situation I'd be looking at something like rubber bump stops or something like that for a car suspension?
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
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
Mine just makes a clicking noise and stops. The red light comes on and stays lit. Tried multiple batteries so it’s not battery issue. Removed the nail holder and the pin looks fine and not stuck. Guess it’s Milwaukee’s problem now. This is the m18 30* framing nailer.
I'm not 100% on that one. It could be that it needs re-gassed or it could be that the cog position sensor is not sending a signal back (broken wire or faulty sensor). Those are pretty much the two common problems with these. I'd also check there isn't any signs of damage to the mechanism (bits of metal broken off).
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
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.
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.
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.
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.
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.
I wonder how long the air pressure will stay in the tank, the cylinder looks very worn. maybe a new seal kit is in order.
Rich
Been ages since I did this video and it's still working fine. Although I don't use it that often.
A great fix, the wd40 and wonder wipes certainly did the job cleaning that up, the blue mat would have been a black one after that lol, lol 😂
Oh yes, the blue mat would have been the black mat 😂😂😂😂😂
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.
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.
Класс! а то думал что придется только выбрасывать когда сломается
Рад, что вы нашли это полезным!
Hi guys ! Does anyone know part number of the rubber ring for the Milwaukee 2744-20 or its size?
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.
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.
Wonder how long air lasts versus nitrogen
I'd say no different, depends on how leaky your gun is. Air is 80% Nitrogen anyway.
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?
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.
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).
O think that’s where the problem all starts with the WD40. Am gonna use air tool oil to fix this one I have. Paslodes are always messing up if you use WD. Thanks for the vid though 👍🏻
Thanks, and thanks for the tip. After making the video a few people suggested silicone grease.
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
@@user-bq1xt5eq1y 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.
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
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
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 👍
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.
De donde se consiguen las piezas
Si te refieres a la bomba y el adaptador, los compré en eBay, busca la bomba de estribo.
The gas required replace it ?
I'm not sure of the original gas (possibly nitrogen?), but plain old compressed air seems to work just fine. I just used an air rifle stirrup pump, as you need about 160 PSI, and normal compressors etc don't usually go that high.
Hi man. I have one and when I press the front of the gun into the wood to nail, sometimes it's as if something's jamming it or stopping it from going back to allow me to fire a nail. Do you know any fix for this? Thanks.
I'm not 100% on that one. Could be a problem with the motor or like you say something jamming it. Only thing I could suggest is taking it apart and inspecting it for debris that could be jammed.
What size of bit do I need to open the gun up?
It's a T20 security torx the one with the hole in the centre. Also a T25 to remove the magazine
Top man cheers
where can i get the pump?
I already had a pump for an air rifle, but I originally bought it from Ebay. Just look for PCP pump. I had to put a 1/8" bsp adapter on it to make it fit the cylinder. Dont worry about pressing the centre of the valve as the pressure will just force it open.
Great repair but I have 2 questions.
What kind of grease did you use? Why use WD-40 instead of using brake cleaner?
Thanks. Good questions! Just general purpose lithium grease because I had some for general farm machinery. WD-40 because that's what I had, and I didn't have any brake cleaner :)
Doesn’t brake cleaner dissolve a lot of plastics? I always think of WD40 as pretty innocuous.
@@gf2e break doesn't dissolve any of the plastic, that's a myth. Brake cleaner is commonly used for cleaning paslode framing gun and WURTH branded framing nailer and they contain plastic parts
@@tobykilby3631 also PA6 GF30 is chemical resistant.
Also WD-40 is known and proven to corrode orings and seals so good luck with that never use WD-40 near anything that is a sealed unit
What kind of fitting adapter did you use to go into the tank?
All of info is in the video description..
I can only find NPT fittings do you think that will work?
I'm not 100% sure on that. The adapter I used actually came with the air gun stirrup pump I used.
Can’t get the hose off quick enough. Pressure isn’t sticking.
The valve in the filler should stop anything coming out. Nothing should come out when you remove the hose.
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.
