Compressor Reassembly

Clean all compressor parts, use a suitable solvent with proper precautions. Coat all moving parts with the proper
compressor oil before assembly. Refer to
7.8.4

Preparation

a. Suction and Discharge Valves
If the valve seats look damaged or worn, replace valve plate assembly. Always use new valves because it is diffi-
cult to reinstall used valves so that they will seat as before removal. Any valve wear will cause leakage.
