Compressor Shaft Seal Install HT6/HD6

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. Dip the new seal seat O-ring in clean 525 viscosity refrigerant oil. Assemble the new seal seat O-ring onto the J 33011 .
2. Insert the J 33011 into the compressor neck until the installer bottoms.
3. Lower the moveable slide of the J 33011 in order to release the O-ring into the seal O-ring lower groove. Do not release the O-ring into the compressor neck top groove.
4. Rotate the J 33011 in order to seat the O-ring.
5. Remove the J 33011 .



6. Dip the new seal in clean 525 viscosity refrigerant oil. Assemble the seal to the J 23128-A by turning the handle clockwise.
7. Engage the knurled tangs of the J 23128-A with the stamped steel case side of the lip seal (1) in order to ensure that the flared-out side of the lip seal (1) faces toward the compressor.

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

8. Install the seal using 1 of the 2 following methods:
9. When using method 1 do the following:



10. Install the J 34614 in the seal lip.

10.1.

Place the seal lip over the compressor shaft.

10.2.

Push the seal (1) into place using a rotary motion.

11. When using method 2 do the following:



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



13. Slide the new seal (1) onto the shaft using a rotary motion until the seal stops.

13.1.

Ensure that the seal contacts the O-ring. Do not dislodge the O-ring. Disengage the installer from the seal.

13.2.

Remove the J 23128-A and the J 34614 .




14. Using the J 5403 , install the new seal retainer ring (1) with the flat side against the seal. Use the sleeve from J 33011 in order to press in the seal retainer in order to ensure that the seal snaps into the groove.
15. Leak test the compressor. Refer to Compressor Leak Testing .
16. Remove any excess oil from the shaft and from the inside of the compressor neck.
17. Install the clutch plate and hub assembly. Refer to Compressor Clutch Plate/Hub Assembly Install (HT6/HD6) .
18. Remove the compressor from the J 34992 .

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.
