Compressor and Block Fitting

Compressor and Block Fitting


A defective or a worn-out shaft seal often causes compressor gas leaks. A small amount of compressor oil leakage from the shaft seal is normal. Replace the compressor only when a large leak is detected. At times, an oil leak can be detected visually. A gas leak check will require a gas leak detector.
1. Blow shop air behind and in front of the compressor clutch/pulley for at least 15 seconds:
2. Probe the compressor area. If the detector goes to a solid alarm, a leak is present.
