Compressor Shaft Seal Install V5 - Conventional Mount

Tools Required

Notice: Seals should not be re-used. Always use a new specification service seal kit. Be sure that the seal to be installed is not scratched or damaged in any way. Make sure that the seal is free of lint and dirt that could damage the seal surface or prevent sealing.

1. Thoroughly clean the seal O-ring groove in the front head.
2. Dip the new seal O-ring in clean 525 viscosity refrigerant oil.

Notice: Any attempt to use makeshift or inadequate service tools or equipment may result in damage and/or improper compressor operation.

3. Assemble the O-ring onto the J 33011 .
4. Install the O-ring.

4.1.	Insert the J 33011 into the compressor neck until the installer bottoms out.

Important: The top groove in the compressor neck is for the shaft seal retainer ring.

4.2.	Lower the moveable slide of the J 33011 in order to release the O-ring into the seal O-ring lower grove.

4.3.	Rotate the J 33011 in order to seat the O-ring.

4.4.	Remove the installer.




5. Dip the new shaft seal in clean 525 viscosity refrigerant oil.
6. Assemble the seal to the J 23128-A by turning the handle clockwise.

6.1.	Ensure that the stamped steel case side of the lip seal engages with the knurled tangs of the J 23128-A .

6.2.	Ensure that the flared-out side of the lip seal faces toward the compressor.

Notice: Use care when handling the seal protector. Do not nick the seal protector. This may damage the seal during installation. Ensure that the bottom of the seal protector is not flared. This may damage the seal during installation.

7. Install the J 34614 on the lip seal.
8. Install the lip seal onto the shaft.

8.1.	Place the J 34614 over the end of the compressor shaft.

8.2.	Slide the new seal onto the shaft using a rotary motion of the J 23128-A .

8.3.	Ensure that the seal makes good contact with the O-ring.

Do not dislodge the O-ring.

8.4.	Disengage the J 23128-A from the seal.

8.5.	Remove the J 23128-A and the J 34614 from the compressor.




9. Use the J 5403 in order to install the new seal retainer ring with the flat side against the seal.
10. Use the sleeve of theJ 33011 in order to press in the seal retainer ring. Ensure that the ring snaps into the groove.
11. Leak test the compressor. Refer to Compressor Leak Testing (V5 -- Conventional Mount).
12. Remove any excess oil from the shaft and the inside of the compressor neck.
13. Install the clutch plate and hub assembly. Refer to Compressor Leak Testing (V5 -- Conventional Mount).
14. Install the compressor and the compressor belt. Tighten the bracket.
15. Evacuate and charge the refrigerant system using the J 39500-B .

Compressor Shaft Seal Install V7 - Direct Mount

Tools Required

1. Dip the new A/C compressor shaft seal (1) in clean 525 viscosity refrigerant oil and assemble the seal onto the J 42136 , by turning the handle clockwise.
2. Install the J 34614 onto the A/C compressor shaft.
3. Using a rotary motion, slide the new A/C compressor shaft seal onto the A/C compressor shaft until the seal is fully seated.
4. Remove the J 34614 by turning the handle counterclockwise.



5. Install a new A/C compressor shaft seal retaining ring (2), using internal snap ring pliers (1).

Make sure that the chamfer side of the retaining ring is facing up and that the retaining ring snaps into the groove.




6. Leak test the A/C compressor, using the J 39893 .

6.1.	Install the J 39893 onto the A/C compressor and pressurize the suction and high-side of the A/C compressor with R-134a.

6.2.	Temporarily install the shaft nut.

6.3.	With the A/C compressor in a horizontal position, rotate the A/C compressor shaft in the normal direction of rotation, several turns by hand.

6.4.	Leak test the seal area and repair if necessary.

Remove the shaft nut.

7. Recover the refrigerant.
8. Remove the J 39893 .
9. Remove and clean any excess oil resulting from installing the new seal parts from the shaft and inside the A/C compressor neck.
10. Install the A/C compressor clutch plate and hub assembly. Refer to A/C Compressor Clutch Plate/Hub Assembly Install (V7 -- Direct Mount) .
11. Remove the A/C compressor from the J 41790-A .
12. Install the A/C compressor into the vehicle.
