air compressor wont fill

[1930artdeco]

Hi All,

So I was busy painting away with my compressor when it stopped pumping up suddenly. did some basic trouble shooting and cleaned the valves of gunk-no dice. Ordered new valves (champion compressor) and still nothing-well it pumps to 20 psi. That and the piston hist the new valves as I saw mark from the rivet in the piston head.

So..I took out my handy dandy IR gun and took some readings. These are of the ex. valve and pipe left to right.

left ex. valve: 129
left ex. pipe: 129

right ex. valve: 156
right ex. pipe: 141

pipe as it goes into the valve before tank: 105

Is it possible the check valve or the gauge has gone bad? What am I missing here.

Mike

I have a Husky that is doing the same thing, keeps running won't pump up to full pressure, I cleaned the reed valves and still no change, it does pump air out of the head, and I am thinking it might be a bad check valve but I am not sure yet
