Front and Rear Gaskets and Seals

Install or Connect:
Tools Required:
J 34614 Shaft Seal Protector
J 33942-B Seal Seat Remover

IMPORTANT
Do not reuse shaft seal gasket O-rings, front or rear compressor seals, or washers. Use new washers and a compressor gasket set. Before beginning reassembly procedures, make sure that all parts are clean and that the work area is clean.

1. New compressor seal to rear of compressor. Lubricate seal with compressor oil.

2. Two pins on rear of compressor.

3. Suction valve, valve plate and reed valve to rear of compressor, lining up the plates with the two pins.





IMPORTANT
The front and rear suction and reed valves are identical. The front and rear valve plates are marked "F" and "R" (Figure 14).





4. New rear gasket; lubricate with compressor oil prior to installation (Figure 15).

IMPORTANT
* The front and rear gaskets are different (Figure 16). Do NOT interchange them.
* Assemble gaskets so that their protruded surfaces face upward.





5. Rear housing to compressor (Figure 17).

6. New compressor seal to front of compressor. Lubricate seal with compressor oil.

7. Two pins on front of compressor.

8. Suction valve, valve plate and reed valve to front of compressor, lining up the plates with the two pins.





9. New front compressor gasket; lubricate with compressor oil prior to installation (Figure 18).





10. Front compressor housing and five through bolts and new washers (Figure 19).

IMPORTANT
* Do NOT reuse the five old front housing washers.

Tighten:
* Compressor through bolts to 27 N-m (20 Lb.Ft.).

11. Compressor shaft seal.





A. Coat the J 34614 with compressor oil and install onto compressor shaft (Figure 20).





B. Apply compressor oil to shaft seal O-ring and install compressor shaft seal onto J 34614 (when fitting the shaft seal onto the J 34614, be sure to have the O-ring facing down, Figure 21).

C. Place the J 33942-B onto the shaft seal

NOTICE:
Do NOT use a press, hammer or other similar tools to press the J 33942-B or shaft seal into place. Damage to the compressor or compressor shaft seal may occur.





D. Using hand pressure only, slowly press the J 33942-B to seat the shaft seal (the shaft seal upper face must be beneath the snap ring fitting groove when seated) (Figure 22.)

12. New snap ring using snap ring pliers.

13. New oil felt and retainer inside the bore.





* Pour new compressor oil into compressor through service valve opening. Add the same amount of oil that was removed at the beginning of the overhaul procedure (Figure 23).

IMPORTANT:
* If a new compressor is being installed, it is shipped from the factory with 80 ml (2.7 FL.OZ.) of compressor oil in it. Drain 40 mi (1.4 FL.OZ.) of oil from the new compressor before installation, as that much oil remains in other components within the vehicle's refrigeration system.





14. Joint service connector. Lubricate new O-rings with compressor oil (Figure 24).

Tighten:
* Four joint service connector bolts to 27 N-m (20 LB.FT.).

IMPORTANT:
* The suction port has a larger internal opening than the discharge port. The O-rings are not interchangeable.

15. A/C compressor clutch. Refer to "A/C Compressor Clutch" earlier in this section.

Inspect:
* Compressor shaft rotating torque. Torque should be less than 3 N-m (27 LB.IN.).
