RIDGID OF45150A Compressor Problem

[hunter5]

I have a RIDGID dual tank compressor model OF45150A that I recently replaced the piston and cylinder assembly on because it would not build pressure. After replacing these parts the compressor takes 20 minutes to build pressure to the point where it will automatically shut off. That is the first problem. The second problem is that after I start using the compressor it will not maintain pressure. I have to keep stoping what I am doing and give it time to build pressure again. Could there be another issue that I need to look at and if so where should I begin? The regulator does leak a little but it has always done that so I do not think that the regulator is the issue.

Hi Hunter5,
Any time you replace the cylinder and piston/rod in a oil less compressor you need to replace the reed valves.That is from the top of the cylinder to the bottom of the cylinder head. It sounds like you have a worn reed valves.Also check the check valve out of the tank.Hope that helps.Good luck.
