A/C Compressor Front Seal Leakage
(Supersedes 88-038, dated DEC 1988)
SYMPTOM
The A/C warning light comes on intermittently and/or the compressor clutch is slipping.
The customer complaint may be that the A/C is performing poorly (if they do not notice the warning light is on).
CORRECTIVE ACTION
If the warning light is coming on or the A/C clutch is slipping, check the shaft seal for leakage, usually the clutch and pulley will be coated with burnt oil
if the seal is leaking.
Replace the A/C compressor seal as described in section 22 of the Service Manual.
The following guidelines should be followed in addition to those in the manual:
^
Keep the shaft and housing clean. Use brake/contact cleaner for final cleaning before reassembly.
^
Lubricate the seal and seat with compressor oil.
^
The O-ring is packaged with a felt seal, so make sure the O-ring is not contaminated with lint from the felt seal.
^
Install a new style compressor clutch set.
^
Check the air gap clearance (should be 0.4 - 0.6 mm).
^
To be sure the compressor oil level is correct, add 20cc Suniso 5GS (or equivalent) refrigerant oil.
^
Make sure the A/C wire harness is the latest design (reter to Service Bulletin 88-015 in the Accessories section). If not, update the harness.
