craftsman 7hp 60 gal 919165611 new rods piston and check valve.


I put new pistons rods sleeves and cleaned reed valves which look good a check valve in the compressor and it takes forever to get to 90lbs of pressure and doesn't ever reach shut off point which is 150lbs what am I missing

Low pressure??

OK. which kit(s) did you use?

I gather you're telling us the check valve works, so it doesn't lose pressure when stopped but doesn't build either.

So 90PSI suggests the HP side isn't working, just passing low side pressure. The intake valve is supposed to act like a check on the hi side, maybe isn't closing fully. Sometimes there is a limit finger - if that's broken or missing it can cause this.

Finally, did you use a torque wrench, or just "feel" it?

Did you also replace the rings and gaskets?
