1. First I removed both the heads.
2. Removed the unloaded valves and replaced them
3. Removed and replaced the intake and the exhaust check valves along with the o-rings and the gaskets.
I used a parts break down and ordered the parts. The parts where correct and easy to install. It took about 2 hours and 3 cups of coffee. Very satisfied.

Air was leaking from my compressor out of the air intake filter. The compressor was constantly refilling itself after idling for only about 15 seconds

I removed the piston unloader from the top of the pump and saw that the brass piston had broken. I simply screwed in the new piston unloader to the top of the pump and the compressor didn't leak any air. I also replaced the spring and o rings that were around the piston unloader while I had them apart. A simple fix thanks to ereplacement parts!
