Compressor Shaft Seal: Testing and Inspection
Seal Leak Detection
A shaft seal should not be changed because of small amounts of oil found on an adjacent surface. The seal is designed to leak some oil for lubrication
purposes. A shaft seal should be changed only when a large amount of sprayed oil is found, and only after actual refrigerant leakage is found by using an
approved leak detector. J 39400 or equivalent.
