• Scoring, cracking, distortion or excessive running clearance

• Air, oil or coolant leakage associated with the internal failure

• Metal debris, overheating or seizure during compressor inspection

Service / Installation Notes:

• Inspect the complete compressor for bore, crank, bearing and valve damage rather than replacing one internal part in isolation

• Confirm that internal components are serviceable separately for the exact compressor version and serial number
