Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
Note: During compressor clutch removal DO
NOT pound on the clutch or compressor as
damage will result.
Step 1: Diagnose Clutch Failure
Most compressor clutch failures are a direct
result of an A/C system problem or failure.
Before installing a new clutch, determine what
caused the old clutch to fail and fix the system
problem. By simply replacing the clutch without
fixing the cause of the clutch failure, the new
clutch may fail in the same manner as the old
clutch. Please refer to the Warner Electric "Air
Conditioning Clutch Trouble Shooting Guide"
and the appropriate manufacturer's A/C
Service Manuals.

Installing Clutch on Compressor
Replace the complete clutch to ensure required
performance is achieved and warranty
requirements are met.
Step 1: Preparation of Compressor
A. Clean compressor nose of all dirt, grease
or debris. Check for evidence of oil leakage
from the front seal and through bolts of the
compressor. Repair or replace compressor
as appropriate.
B. Check mounting surfaces for nicks, burrs and
scratches (See Figure 1). Smooth with a file
or emery cloth, if necessary.
B. Remove field coil snap ring (3) retaining the
field coil.
C. Remove the ground screw on the compressor,
if used.
D. Slide the field coil (2) off the compressor
housing.
Figure 1
C. Make an electrical system check with all
