Craftsman Air Compressor - Harbor Freight Regulator Repair | CBH

- เผยแพร่เมื่อ 3 พ.ย. 2021
- We have this old 220V twin cylinder Craftsman air compressor. We couldn't leave it on because it leaked so badly from the regulator it cycled on and off almost continually. Nothing like being rattled awake by this thing kicking on at 2am... So we got a replacement regulator from Harbor Freight and fixed it. Its working perfectly and is a true workhorse of a compressor for larger projects.
These look great for home self defense!!!
My dad told me the Teflon tape trick and I’ve always remembered it. Hold the threaded piece in your left hand. Start the tape on the bottom side of the threads and wrap it clockwise.
Awesome! Yes that helps! I don’t know why after as many joints that I’ve used teflon tape on but I always have to think about it way too hard…. Lol
Thanks again! Have a great day!
If the leak is near the pressure switch, we can say the tank pressure is not being held back by the one-way check valve as one reason.
Craftsman was smart to get these made sealed for profit marketing on fittings. You can not open the A19712-Check Valve, service the rubber stopper for debris, to increase spring tension and flatness for sealing the seat or rubber. It's only the check valve with the snap ring retainer clip capable of being inspected.
The second leak reason does occur from the air regulator diaphragm is ruptured.
The third rupture point is under the pressure switch monitoring the actual tank pressure. It's best to use soap bubble test.
Thanks for the find!

Very helpful video!! I also have an older craftsman that look just like this one. I am going to try this method out!
Thanks for watching and your comment! Good luck with your compressor and have a great day! Be safe! ❤️
Thank you for video
Absolutely! Thank you for watching and your comment! Have a great day and be safe!
Excellent video. Thank you for your effort.
I've just bought the same compressor for almost nothing. Unfortunately it wasn't working hence the cheap price so I will be using your video when I come round to working out what needs to be fixed.
Thanks for watching and your comment. Good luck with your compressor. Have a great day and be safe.
Thank you. You also.
Love your video!
Thank you so very much ❤️
I just bought same model off marketplace, replaced the regulator, worked fine, but went to adjust the switch and im missing the plastic cut-off screw...so now it just leaks once it gets to a certain pressure right out of that cut off screw hole. tried to look for a new screw adn the parts for it are absolete so guess now I will be buying a whole new switch along with pipe/fittings if needed....thought I was getting a steal -"$50" but its gonna end up costing more than I assumed...live and learn! on the flip side, I now feel like I can buy any used compressor and fix them with ease!
Thanks for watching and your comment. Great job getting your compressor figured out. Anytime I learn something on a project I feel like it was a win. So great job winning! Have a great day and be safe!
I am really jealous of your Barn Copper Barn Homestead
Thank you, appreciate you watching and the comment. Have a great day and be safe!
Looks like a 5-20p for A 120v 20 Amp receptacle.
Thanks for watching and commenting, appreciate you!
I have same model, my dad gave me. I think its leaking out the manifold. Not holding air, compressor motor seems to be working ok. Or could be the regulator, I told the old on apart didn't seem to fix it. I will get a new one like you did and see if that is it.
Thanks for watching and your comment. They are/were great compressors ours was leaking at the regulator. Have a great day and be safe!
One question. Did your pressure switch work properly with just the tank pressure gauge by itself? I have the same compressor. I made the same mistake of putting both gauges on the regulator and now the motor won’t stop. I’m leaving the shop now to go get another gauge but wanted to also ask.
Thanks for watching and your question. Yes the compressor turned on and off with just the tank gauge, I just couldn’t see the regulated pressure. Have a great day and be safe!
Good video but honestly, I think just buying the original Craftsman part would’ve been a lot easier, cheaper, and less headaches with all those additional parts you had to buy.
Thanks for watching and your comment. That is possible, I never even checked to see if that part was available, we got that compressor from Sears around 1992 or so. I pass 3 Harbor Freight stores on my way to work and they have the stuff on the shelf. I’m positive Craftsman parts would not be cheaper even if you could find them. For me sometimes finding another way to do something is enjoyable as well. On the other hand having something as it came from the store working as new is also cool and makes a case for finding original parts. Thanks again for watching and the comments! Have a great day and be safe!
I have the three HP, 15-gallon tank and the same problem.
Yes, seems like a common problem with the older ones. Thanks for watching and your comment. Have a great day and be safe
Helped me
Awesome! Thanks for watching and your comment! Have a great day and be safe!
What was the HF part number you used for the regulator ?
Hey, thanks for watching and your question. 58183 should be the part number of the regulator used to the best of our memory. Hope that helps, good luck and stay safe!
Does this regulator change/ alter the scfm capabilities at 40 or 90 psi?
Thanks for watching and your comment. Actually thats a good question and I don’t even pretend to know that answer. The compressor still runs everything it did before the change if that helps. Have a good one and be safe ❤️
The SCFM is a metric that mostly means "how fast can the compressor refill the tank at a certain pressure" the regulator itself will regulate the air pressure out. For example, this compressor can continually push out 6.4 (standard)cubic feet per minute at 90psi. The regular will adjust how much PSI you want it to let out.
My pressure switch stopped cutting the power off. Where can you adjust the pressure switch of find a replacement one?
Thanks for watching and your comment. You can find them on Amazon or eBay. Then if you have a Granger type place locally you can get them there as well. Good luck. Have a great day and be safe!
I have this same compressor. I have a couple leaks that I tried to fix with Teflon tape. I am trying to figure out why it builds up pressure,but will never cycle off. It is constantly going no matter what I set the tank pressure to. Any idea of what I need to do?
Thanks for watching and your comment. I honestly don’t know and am not an expert on air compressors at all. If I was looking into it I would see if it is leaking at any of the fittings or the drain valve or pressure relief valve even. If it never builds enough pressure to shut off it might even have a leak in the tank itself. If it builds enough pressure to shut off but doesn’t it might be the pressure switch but that could be a very dangerous situation so use extreme caution even trying to diagnose the issue. Sorry if this wasn’t as helpful as you hoped, good luck with your compressor but above all be safe! Thanks again for watching and for your comment! Have a great day and be safe ❤️
Constantly going, meaning it just keeps on building pressure and bypassing on the emergency relief valve? Sounds to me like your pressure switch it faulty (does not close the power circuit when setpoint is reached).
My compressor run but won't shut down
@@waynegrant7338 pressure switch is bad.
Is it possible you connected the wrong side to the tank. That may be why it isnt registering.
Thanks for watching and your question. I didn’t actually think of that. I’m not exactly sure if that would change it or not but it’s worth a try. I believe it had inlet and outlet marked but have slept since then. Lol Have a great day and be safe!
So I have this compressor and I was wondering if there anyway I can buy a 110 volt adapter for it to fit my outlet as well? Wondering if you know anything about that
I don’t know of any adapter that would allow you to run a 220v motor with 110v. If there was one it would probably be more expensive than either running a new 220v line or buying a 110v compressor. Ymmv thank you for watching and your comment, be safe ❤️
Yes
Just change the plug in ends
@@waynegrant7338 its not that simple, each wire that leads to motor is wired for 220 volts, if he does not wire them correctly at the plug end ?, he will burn the motor up. now, he '' should '' be able to re-wire the motor itself, as most of these motors will let you convert them from single phase ( 120 ) to two phase ( 220 ). all depends on the motor ?.
I have the same compressor and I need to replace one of the pistons and sleeves. I have a partial model # 919.152,
I can't make out the last three numbers. Do you know what your model # is? I believe mine ends with 930
Hey, thanks for watching and your comment. Looks like ours is 919-15293-2. Hope this helps! Have a great day and be safe!
920
I need you to repair my compressor 😀
Thanks for watching and your comment! I just change parts and it usually works out! Lol
Have a great day and be safe!
I have a craft man air compressor 4 hp 25 gallon tank I replaced the switch but now it just keep running won't shut down
Thanks for watching and your comment. Yeah that is a problem. Not sure where to begin sorting through that issue but obviously, it needs to be wired correctly and then check for leaks. If nothing there fixes might be time for a new compressor. Good luck and remember compressors can be dangerous if they don’t work correctly so above all else, be safe!
@@CopperBarnHomestead what do you think the problem is ,?
@@waynegrant7338 honestly not sure. I might try switching it back and see if it’s any different? Good luck, be safe!
My 33 gallon Craftsman air compressor won't shut off by itself no more
Thanks for watching and your comment. Sounds like either an air leak keeping it from building up enough pressure to switch off or a bad pressure switch. Good luck and be safe! Appreciate you ❤️
That is not 220 volts
Hi, thanks for watching and your comment. Other people have said that as well. The name plate says 240v and it has the factory plug on it. I found this on Amazon that looks identical.
NEMA 6-20P Replacement Plug Easy Assembly - Durable Nylon Construction - WB620P - Rewireable NEMA 6-20P Rewirable Plug, User Attachable, Replacement Plug, Grounded 3 Wire, 20 AMP 250 Volt, WB620P Black & White, with Speed Screws & Easy Wiring Assembly - Made of Durable Nylon Material - Commercial & Industrial Grade
So I am not certain why anyone sees something else but I am certain it is a 220v compressor and has been operating on 220v since new. Ymmv have a great day and be safe!
