Tools Required:
J 5403 External Snap Ring Pliers
J 9553-01 O-Ring Remover
J 23128-A Seal Remover and Installer

1. Clutch plate and hub assembly.
2. Shaft seal seat retainer ring using J 5403.

Clean
- Inside of compressor neck area and O-ring groove surrounding the shaft, the exposed portion of the seal seat and the shaft itself. Any dirt or foreign material getting the compressor may cause damage.

Removing The Shaft Seal With J 23128-A:

3. Shaft seal (12).
- Fully engage the knurled tangs of Seal Remover-Installer J 23128-A into the recessed portion of the seal by turning the handle clockwise. Remove the seal from the compressor with a rotary-pulling motion. Discard the seal. The handle must be hand-tightened securely. Do not use a wrench or pliers.

Removing And Installing The Shaft Seal:

4. Seal seat O-ring from the compressor neck using J 9553-01.

Inspect
- Shaft and inside of the compressor neck and O-ring groove for dirt or foreign material and be sure these areas are perfectly clean before installing new parts.

Inspection
- Seals should not be reused. Always use a new specification service seal kit on rebuild. Care should be taken to prevent damage to the lip of the one piece seal. Make sure that the seal seat and seal lip are free of lint and dirt that could damage the seal surface or prevent sealing.

Install or Connect

Tools Required:
J 33011 O-Ring Installer
J 23128-A Seal Seat Remover and Installer
J 34614 Shaft Seal Protector
J 5403 External Snap Ring Pliers
J 9625-A Pressure Test Fixture

Installing The Seal:

1. New O-ring seal, dipped in 525 refrigerant oil, onto J 33011.
2. Insert J 33011 completely down into the compressor neck until it bottoms. Lower the moveable slide of J 33011 to release the O-ring into the seal seat O-ring lower groove. (The compressor neck top groove is for the shaft seal retainer ring.) Rotate J 33011 to seat the O-ring and remove.
3. New shaft seal to J 23128-A.
- Insert by turning handle clockwise, and then push J 34614, into seal lip. The stamped steel case side of the lip seal must be engaged with knurled tangs of installer so that flared-out side of lip seal is facing and installed towards the compressor.
4. Shaft seal.
- Place J 34614 over end of compressor shaft and slide new seal onto the shaft until it stops. Disengage installer from seal and remove J 34614 from compressor shaft.

NOTICE: Handling and care of seal protector is important if seal protector is nicked or the bottom flared, the new seal may be damaged during installation.

5. New seal seat retainer ring using J 5403.
- Insert new seal seat retainer ring with its flat side against the seal seat, using J 5403. Use the sleeve from J 33011 to press in on the seal seat retainer ring so that it snaps into its groove.

Compressor Leak Testing:

6. Leak test as necessary.
- Install J 9625-A onto the rear head of the compressor and connect gage charging lines, or pressurize suction side (low pressure side) of compressor on vehicle with Refrigerant-12 vapor to equalize pressure to the drum pressure. Temporarily install the shaft nut and with the compressor in a horizontal position and using a wrench, rotate the compressor shaft in normal direction of rotation several times by hand. Leak test the seal and correct any leak found. Remove, discard and later replace with a new shaft nut.
7. Excess oil, resulting from installing the new seal parts, from the shaft and inside the compressor neck.
8. Clutch plate and hub assembly.
