How to repair a Kobalt model 3332643 air compressor regulator!

Repairing my Kobalt air compressor. Pressure regulator (tool side) stripped out the shaft that cranks the thing in to increase pressure. NO PARTS AVAILABLE I COULD FIND! How I repaired this quick and better than it was originally.

    If the spring gets weak I wonder if you could put a washer or two in there to give it a bit more push action.

    Spring isn't weak, the threads strip out because of the spring pressure.

    So I came across your video because I had the same issue. I thought about attempting your repair but don’t have the knowledge or tools you do. The only thing that concerns me about your repair is I am afraid that since the regulator is aluminum or some other soft alloy the same this will happen again in 2-3 years. I ended up repairing mine with a helicoil. So far it is holding but it’s been only a few days.

    That’s fine. You’re right it’s cheap Chinesium metal. I thought about that and just greased it heavily. Will have to go back in from time to time and re-grease it.

    I followed your repair and fixed my compressor. Very cool. Only problem is I didn't replace the knob. I only have a bolt. I don't have a metal lathe and when I backed the bolt out it unscrewed all the way out. The 5mm screw came out of the end of the bolt. Perhaps CA glue on the screw will stop it from unscrewing. Thanks for the guidance.

    I used blue (non-permanent locking agent, technically) on mine, it's actually a Permatex product. Good dose on that tiny screw does it. My first repair, the screw did back out, the second, it stayed as I used more product. I basically douched the screw in blue. Just did another one for someone and I douched it the same. But super glue would work fine also. If you ever had to take it apart again, heat from a bic lighter or pen torch would soften the glue enough to get it out. Really, that should be a left-hand screw and it would never back out on its own. I'll have to look into that. Cheers.

    I was thinking why not just grind a knob on the end of the bolt like the screw? Oh, by the way I got an email from Kobalt today. They are shipping me a new regulator. Not sure if it's the entire manifold or just the chinieseum part.

    Instead of drilling the 5mm hole and tapping The 8mm bolt it why not just grind or machine a round end to match the 5mm round head screw? Then it would never back out. Just a thought. I did drill and tap it like you did.

    @@longdriver2 That end needs to be slightly larger than the major diameter of the screw. It's actually a 10mm, not 8mm screw. A bolt converted into a screw, to be technical. This prevents the end from coming through the threads, obviously. I'm still not understanding how the end could be ground or machined to make it larger than it's original major diameter. Material would have to be added, not removed, hence, the screw/washer which is larger than the screw itself. Perhaps I am dense, but I can't understand what you are suggesting.

    Great video. I have the same compressor and am on my second regulator. Like the original, it leaks, so I can't leave pressure to the tool port or it runs too frequently, the compressor gets hot and trips the circuit breaker. Absolute garbage.

    Very informative Video. I haven't finished watching yet (@ 22:16 now). After seeing what you've shown so far, I would recommend to install a Helicoil to repair the damaged Female threads in the Alloy piece, reassemble with Wheel Bearing Grease and you're done. As a side note, I wouldn't be fiddling about with releasing pressure each day (which is what caused your premature Regulator Failure), an alternative recommendation is to install a "Ball Valve" before the Hose to lock in Pressure as I have seen a few air hose failure's overnight during my 43+ Year Career as a Professional Wrench (One time in particular that a whipping hose hitting a Car at a Dealership caused a lot of damage).

    You’re right about the threads I can feel them getting problematic already. That’s on my list. My habit of releasing pressure comes from years in the fire department where we had to do that when we used the cascade system to refill SCBA bottles. It’s to protect the regulator, not the elements downstream. Cheers.

    @@MotoRestoFL I stumbled upon your wonderful video while trying to decide between the Kobalt Compressor you have or purchasing a Model # 20020 California Air Tools 20 Gallon unit for an additional 176 Dollars from Lowes Online (Ordered the 20020 / expecting delivery on February 27th Monday), your video and many others revealed the Kobalt's Pressure Regulator to be of poor quality and helped me decide not to get the Kobalt. Had I decided to go with the Kobalt I would have opted to build my own Manifold with a Milton Regulator. I've already ordered a pair of Milton S-786 1/4" MNPT "T" Style Couplers which I like much better than the "M" Style Generic Couplers that are included the the California Air Tools Air Compressor 20020.

    Thanks for this video. Because of you video where you detailed how the regulator was assembled, I was able to take mine apart. Unfortunately, I won't be able to fix it, as the issue with mine is that the small spring in the pressure valve is corroded and has failed. So now I have either full tank pressure to the tool or it leaks until the tank is empty.

    You need only a spring to make it work? Measure what's left of that one and/or the space it occupies inside the regulator (I don't exactly recall how large it was) and go on amazon. You can most certainly find air compressor/regulator springs or spring kits.

    I see everything. I know nothing. Lol. Seriously, I think you’re spot on. Take it apart and inspect it, grease the thing well. The grease helps but the main issue is the pot metal that the threads are made into. They’re probably not even cut threads, probably molded. If you buy this and I assume it’s used because they’re discontinued to my knowledge, I’d replace that thread with a Time Sert ASAP. If you get to that point and want me to install one, send me the regulator I’ll do it for free labor just the cost of materials and shipping, in exchange, like/share and subscribe, perhaps recruit some friends to do the same.

    Just ordered on of these, doubt the issue has been addressed by Kobalt? Question, when this assembly fails, does the valve fail open or closed? Just curious as I have a secondary high quality regulator and dryer downstream of the compressor, so I am guessing I really don't have to have a primary regulator assy (unless the manifold leaks air or it fails closed)?

    Reed valve? It’s a diaphragm under spring pressure and is closed unless the regulator screws into it to open.

    My apologies I read wrong. The valve fails closed as mentioned below. Spring pressure keeps the valve shut until the screw adjustment pushes against the spring and proportionally opening the valve until opened all the way.
