Thank You for posting this 741. Mine has leaked slowly for 10 years and now holds pressure great!
Thanks for the video, it encouraged me to do something I needed to do for a while now. Found several leaks using a spray bottle with soapy water. My regulator parts were all good. Just needed to add Teflon tape. Then hand tighten, then tighten about 1/8 to 1/4 turn with wrench, Tighten all the other leaky connections and the exact same Craftsman compressor you have is holding pressure like it did 20 plus years ago. Good video!
Made my day! My washer was also broken. Your video saved me time and money. THANKS
Been working on my dad's old air compressor for almost 2ys now due to time allowed to work in the garage. Thank you for this video!
WOW! Exactly what's happening with mine. The plastic washer on my air compressor looks like the letter "C". I thought it was supposed to look like that! PS: When I put the knob and spring back together, it was easier to put it all together BEFORE placing it back on. Can't wait to try this.
Thanks for the video. I didn't have the broken washer issue, but your video showed how to take it all apart. I found the rubber diaphragm thing had some type of coating of dirt/oil on it. Cleaned it up and runs perfect now!
Buddy I just want to Thank you. My Craftsman wasn't building or keeping full pressure. Followed your video and viola, the same broken plastic gasket. I used the Right Stuff sealer and some Permatex high performance thread sealant paste. Not only has my compressor reached max pressure but for the first time in 16 years she has held a steady 90 psi in the tank for over 24 hrs. Bro you the bomb. Thanks again.
Glad my video helped!
Thank you very much for making this. I have the same compressor with the exact gasket problem and this perfectly met what I needed. And I had the rtv gasket maker and Teflon tape already so it was quick and easy.
Same here! Great video. Thanks!
I have an old one like that, probably 28 years old. I had to teflon the fittings, but it still has a minor leak.
Still, it has served me surprisingly well with the only service being draining out the water periodically.
I’ve got the devilbiss version. Exact same regulator. Exactly what I needed! Thank you
part number?
I have the exact same compressor with the exact same problem. It was inherited from my grandpa, so I don’t want to get rid of it. I’m going to fix it this week. Thanks!
you hit the nail. watching ur video showed me how to fix problem in my garage. Saved my son a lot of $$$... Thanks... (ps. he did not tip)!!!
Thanks for the video !! I have the same problem and it just needed cleaning up. But I was hesitating to do it until I saw this.
I did the gasket sealer trick on mine, the white washer was in pieces. I'll let you know it it works tomorrow! Thanks
Very informative and well presented. Attaboy on a successful fix. I've used plastic milk bottles to make washers and other small pieces such as the one you needed when it would have been unlikely to find them otherwise.
Reminds me of using notebook back for gasket
@@BigAl7976 Did a cam change on my friend's '65 GTO and had to use a coffee cup lid for a thermostat housing gasket. Years later I saw the car again, new owner, still had the coffee lid. It was the old style lid with the tab.
Brilliant, exactly my problem, will soon have that sorted, many thanks.
Seriously, thank you for making this video very helpful very clear able to use this on my own compressor 👍
I have one like this as well with the same problem. I tried a 1 1/8" O.D. O-Ring but nothing is coming out. Maybe the 1/8" O-Ring is restricting the diaphragm. I think I'll bleed the air and try your silicone method. Yes, the regulators AC-0007 were much more expensive than I'm willing to pay right now! Thanks for the video!
what can I say your videos are always so good
Thanks! I'm glad you enjoy my vids!
i have same problem was going to take it to shop. but now i will try and fix it myself. Thank you.
Perfect! Very helpful...
Teflon tape isn't made for filling gaps to stop leaks. You should have used just the RTV sealant. Teflon Tape is made to reduce friction so you can tighten a fitting further than you normally would, engaging more threads .
You are partially correct. Teflon tape will make it easier to completely thread your connections, but the Teflon tape itself will help leaking by filling in the groves of the thread, thus creating a seal inside the connector. Been using Teflon tape for years to prevent water and air leaks. I don't recommend using it for liquid fuel, like gasoline. Liquid gas will break down Teflon and may get into things you don't want it to be in. Using Teflon tape in this manner is perfectly fine and less messy than RTV sealant.
The gasket maker RTV comes in handy!
Thanks! I bought the same one off the marketplace and got the same issue!
Thanks for the post.
I have the same compressor, with the same problem.
Subscribed.
Thank you.
Note: the seal being repaired is between the bottom of the diaphram and the housing, The top side of the diaphragm and chamber above the diaphragm are at atmospheric pressure and the threads have atmospheric pressure above them.
I repaired mine with silicone form a gasket applied to the bottom edge of the diaphragm.
Basically gluing the diaphragm to the housing? Do you suspect his RTV sealant squished around the rubber diaphragm sealing it as you did with it on the bottom? And where did the rest of the white ring washer go, mine was only partially there also, no way it went out the air line thru a tool.
Nice video, thank you very much.
Looks like my identical problem. Will have to tear into my regulator. Subscribed, saw ham ham radio subjects as well, 73.
The compressor is an easy fix...shouldn't take you too long. I have a mix of ham/electronics and general repair videos...thanks for your interest!
Great help👍👍
Gonna try this tomorrow on my craftsman. Fingers crossed
You're the man! Thanks
Very helpful,thanks
Thank you for everything it worked out great save me time and money. ATTA BOY!!
Thanks you helped me!!!!
Going to try this. I just ordered the replacement regulator (AC-0007) from Amazon: $135, including tax. I like the idea of saving a buttload of money!
Jeff Lieurance $135 ??? Damn
@@jakestellar4600 A new compressor is about the same money!
Carl Jones uhh HAHAHAHA NOOOO....
Maybe a cheap portable pancake compressor but not cheaper to buy a new one like mine, I got this one from my dad and already fixed the start and run caps now just need a new regulator
@@jakestellar4600 +2 🙄
Part obsolete, no longer available for my Craftsman 20 Gal. Congrats to all Craftsman owners!
although this fixed the issue, it was not the problem. The plastic washer is to prevent the housing from contacting the diaphragm and turning the diaphragm, not to seal anything. Without the washer the diaphragm will turn and break the plastic regulator piece.
Like a cardboard gasket on a kitchen sink strainer, it is only to keep the rubber from turning because it is contacted on both sides. Removing the cover in the future will likely result in breakage.
I want to say the teflon tape didn't seal but thee silicon did the job.
Nice video
Hey Thanks for the vid my compressor had the same problem all I had to do is tighten the ring nut that holds the regular down fixed it,😊 my compressor is a craftsman 6.5 hp twin cylinder 33gal 240v had mine since new 20 years ago and I just replaced the cylinder sleeves and piston rings and gasketsshould last another 20 years.But it's still loud lol
Hey woody woods, I have the 20 year old 25 gallon, just like the one in this video. This last week it started going up to only 80 psi, no higher. would run continuously while I used it to spray paint. Today it is only going up to 40 psi, no higher. I suspect I need new head gasket, but decided to look on TH-cam before going any farther. Do you think this could be a head gasket problem and where does one get parts? Not sure how to even get to the head gasket or do any trouble shooting. Any ideas?
@@johntube2525 Hey johntube here's my kit that I used from TOOLMART Craftsman O Ring Kit For Air Compressor
916014
I just used thread sealing tape on mine no RTV and it sealed up with no air leaks guess I got lucky.
Good 👍
Need help have the same unit but only stay on 60 psi no matter the regulator being turned right to raise psi
I got the same one. My won't cut off when it should be off.
All on amazon, just rebuilt mine. Its like new
i literally had a new regulator control replacement in my amazon cart when i saw this video and it worked exactly as described. Has this been a long term fix for anyone? thanks for the video
Yes, mine is still working without any problems since this video was made
this was very informable, but one suggestion would be that the camera should have been on the opposite side, because the back of his hand was in the way when he was showing how some parts fit on the base of the regulator.
At time line 5:15 I call those pliers 'Channel-Lock". A crescent wrench has a wheel that opens and closes the jaws.
I usually call them water pump pliers...not sure why I said crescent pliers. Slip of the tongue I guess
I haven't heard that term "Water Pump Pliers in a long time".
I have to now work on my Craftsman air compressor.@@SevenFortyOne
My Craftsman compressor won't cut off. It used to. Is there an adjustment to make it cut off at about 110-120lbs?
Crescent pliers was a new one for me lol
Has anyone found a replacment washer/gasket that fits? Got dimensions or a source? I have the same compressor with the same leaky regulator issue.
Great idea! However, does anyone know where to get this replacement regulator that reads both tank and regulator pressures? Mine has missing parts.
Sears parts direct used to have parts for all the craftsman stuff...not sure if they still do or not
Please share the model number of your compressor, I have a Devilbiss but I can see the model number it's worn away, by looking up the model number of yours I can find the part numbers I need any help would be appreciated ty.
Used the Permatex and was able to build up pressure in the tank. However, could not adjust the pressure regulator - it never registered above zero. Bled the tank a couple of times, then refilled -= same issue, but the last time it started leaking from the pressure switch. Any ideas?
Maybe you got some permatex some place it didn't belong by accident and clogged something up. Also make sure all the parts went back together in the correct order and places.... otherwise I'm not sure what could be wrong
After you make the repair are you still able to adjust the pressure or are you stuck with max psi?
Still able to adjust...works the same as it did before repair
Quick question man, what is that valve behind the switch towards the motor? Does yours leak air out when it is running? I feel like my compressor fills up kinda slow and im trying to find out why. Thanks!
This video shows how I repaired that valve....you should watch it
@@SevenFortyOne You repaired the valve inside the regulator. There is another valve, almost like the stem of a bicycle tire that is attached to the end of the tube right behind the switch box. Go to 6:06 . it is the tube in between the motor and the switch. Go to the end of that tube and there is a valve. I just want to know if yours leaks air when it is running
I have a 15 gal craftsman compressor model 919.167241 that will not turn on. I removed 3 screws from one side of the cover. It splits at the top but still does not separate at the bottom so I can remove it and get to the motor snd components.
Comment?
Mine did that. Theres a thermal fuse protector tied to the motor windings under the shroud. My fuse was good but a wire was broken off. 2 Phillip's screws underneath bottom of the shroud realease the motor and all from the rails. Then take a long t-25 to remove shroud fasteners. Lay it on the side where the fasteners come out. You'll see the fuse tied to the copper. Its wrapped up in electrical tape. Good luck!
Do you have a model number ??
I would not have used that gasket just go down to the hardware store..that gasket is going to gail anyway with how much you turn the regulator
Mine won’t shut off.
I have a 6hp 30 but it takes awhile to fill up would u know what's wrong with it
Not much Info to go on here...sorry
Your cylinder/piston ring is wore.
A proper size oring should work!!
Hey I have the same air compressor would you be able to tell me like what on and off switch that is I need the on and off switch the Box I can't order the on and off switch because the model number and serial number worn off on my unit
Mine is model 919.165030...try usi g that number to search for your part...good luck!
@@SevenFortyOne because it looks like the same on and off switch box will work on mine I'll have to look after lunch to see if I can find it
@@SevenFortyOne thanks
The cover looked like the hardest part of the job.
Is that Jim from TTM?
@@SevenFortyOne Naw, I'm just a guy with a leaky craftsman compressor.
Right on .. I thought you might have been an ex-coworker. Good luck with your repair!
Strange design for so called adjustability of tool pressure. Luckily 100 psi give or take will do for these units.
I don't know what happened, but when I turned on the compressor two days later, the tank got up to about 40psi and then the compressor end blew up, pieces everywhere! lol Oh well, time for a new compressor i guess.
CHANNEL LOCKS!! LOL 🙂
That compresor is dusty man, 🙄 clean it with water and soap.
Wrong you never put silicone or like on that , what you could do is get a card board like shoe box and punch out a gasket
I am in a pinch, my compressor is broken and I need to know how to fix it, I don't need to know what you THINK or your half baked non -solutions. I need an answer NOW and your video succeeded in waiting my time.
So why didn't you call a pro? It's not my fault you can't solve your own problem
It may have fixed the problem for now but that's not the correct way to fix the issue. Probably cost more to buy the gasket maker then it would be to buy a gasket. But at least it's his own tool and not fixing it for someone else for a fee.
Sometimes you have to be a little bit unconventional to solve a problem. I had the RTV on-hand so since it was already bought and paid for the fix was almost free and done quickly. If I ordered the "correct" part I would have ended up paying $5-$10 including shipping and would have had to wait for it. And consider this - that $5-10 gasket would only fix ONE machine. A tube of $5 RTV could probably fix 100. Not only that, I'll wager it will last longer than a crappy Chinese plastic washer.
