After rebuild Craftsman 919.167783 won't build pressure past 30psi
Thank you for this site. It is very helpful. My Compressor issues come in two parts. First, my compressor was very slow to build pressure and would only get up to ~120psi. I tore it down and realized that my rings were bad and cyl walls were pretty scored. I ordered a rebuild kit from Craftsman to replace both the cyl & rings. I installed and now I can't seem to get the air compressor to go beyond 30psi. Everything is torqued down properly and I replaced all of the o-rings that were provided. Per your guidelines, I noticed that there was no air coming out of the intake with the compressor running. With it off, I manually turned the wheel and would hear a hiss from the unloader valve area when the piston was on compression stroke. I think this might be the pressure valve, but it was intact when I had it off the first time.
