Compressor Shaft Seal: Service and Repair
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.
Remove or Disconnect
1. Recover refrigerant using J 39500-GM.
2. Loosen and reposition compressor in mounting brackets.
3. Remove clutch plate and hub assembly from compressor as described in minor repairs.
Removing Or Installing Shaft Seal Retaining Ring
4. Remove the shaft seal retainer ring, using snap ring pliers J 5403.
5. Thoroughly clean inside of compressor neck area surrounding the shaft, the exposed portion of the seal, the shaft itself and O-ring groove. Any dirt
or foreign material getting into compressor may cause damage.
