Shaft Seal Installation

NOTE: Install the shaft seal assembly after the cleaning solvent has dried out.

1. Clean the new shaft seal thoroughly with cleaning solvent.





2. Lubricate the shaft seal with refrigerant oil (SUNISO 5GS or equivalent) and install it on the shaft seal remover.

NOTE:
- Use only clean refrigerant oil.
- Do not touch the sealing surfaces of the shaft seal after lubricating.

3. Liberally lubricate the compressor shaft with refrigerant oil.





4. Install the shaft seal onto the compressor shaft aligning the seal case flats with the shaft flats.
5. Press the remover until it bottoms, then turn it counterclockwise as far as it will go.

NOTE: The remover will go lower when the flats are aligned.

6. Turn the remover clockwise, then pull it out.





7. Slide the shaft seal onto the shaft until it seats on the shaft taper as shown.
8. Check the inside diameter of the compressor for score marks or foreign particles.
9. Clean the seal seat with cleaning solvent, then lubricate the seal seat with refrigerant oil (SUNISO 5GS or equivalent).
