Compressor and Block Fitting

A worn 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. For at least 15 seconds, blow shop air behind the compressor clutch pulley and in front of the compressor clutch pulley.
2. Probe the compressor area. If the detector goes to a solid alarm, a leak is present.
