Cool Craftsman compressor

I have a 30 gal upright Craftsman compressor that is @ 4 yrs old. I have rebuilt the compressor and it has worked fine for the last year. I now cannot develop over @ 45 or so Psi and have air bleeding off from the back of the pressure cutoff switch assembly. I replaced this assembly and I still have the same problem. The only other thing connected to this assembly is a small air line from the check valve. Check valve next, suggestions on where to look next? Thanks in advance!

What is the model is your compressor and maybe you can come up with a link that shows it.

The problem could be a dirty or defective check valve.
You might take it apart to inspect and clean it.

Thanks for the reply and info. I have all the paperwork for it just not at hand. I will explore the check valve maybe this weekend and go from there.

Sorry to take so long to get back. I removed the check valve and sure enough was defective visually. I had replaced it during the previous rebuild. I still had the old one on hand so I put it in. The original problem was then solved. Now the compressor runs but will not build up higher than @60 Psi. I broke down the compressor head and piston didn't look too bad but I also had spare parts to re-do the piston and o-rings again. I did this but still got the same result. I have no leaks. Runs but never builds above 60Psi. The only other thing I see in the mix is some sort of reed type valve located on the compressor head plate. I've got about $60 or so into new parts so far so I might as well keep going even though now this would only be my back-up compressor. BTW it's original rating is 135 Psi. Again I'm open for suggestions. Thanks!
