Compressor Inspection

Check the front and rear valve plates for scratched, bent or otherwise damaged parts. Inspect both cylinder heads and both valve plate assemblies for nicks or burrs on the sealing surfaces. Clean or replace if badly damaged. Make sure that all passages in the valve plate are unobstructed. If either the cylinder head or valve plate is cracked, it must be replaced.
