Replacement Compressor Clutch for
Chrysler Automobiles
This compressor clutch has been developed
specifically for automobile air conditioning
applications. Properly installed, it will provide
maintenance free service. The clutch, using a
stationary field principle, DOES NOT REQUIRE
SLIP RINGS OR BRUSHES.
The clutch consists of two major components,
a stationary magnet field assembly and a
rotor-pulley assembly. The field assembly is
mounted on the compressor. The rotor-pulley
assembly is mounted to the compressor
crankshaft and driven by V-belts from the engine
crankshaft pulley. Electricity energizes the clutch
field to couple the clutch magnetically, thus
driving the compressor. De-energizing the clutch
uncouples the compressor.
Service
This compressor clutch automatically
compensates for wear requiring no adjustment
throughout the life of the clutch. Do not
lubricate the unit. If the clutch should fail to
operate, check the electrical circuit to be sure
that the proper voltage is being supplied to the
clutch. Do not attempt to make any mechanical
adjustments on the clutch.
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.

1. Rotor-Pulley Removal
5. Rotor-Pulley Installation
Remove the self-locking capscrew (5) and
washer (4). Insert a 5/8-11 UNC-2B capscrew
in the threaded portion of the hub and tighten.
The pressure exerted by the capscrew on the
end of the compressor shaft will force the
rotor-pulley assembly off without damage to
the clutch or the compressor. DO NOT USE A
PULLER on the outside diameter of the pulley.
This can damage the pulley grooves or the
clutch bearing.
2. Field Removal
Remove the three capscrews (3) and
disconnect the coil lead wire(s) from the vehicle
wires.
3. Compressor Shaft Inspection
The compressor shaft must be clean and free
from burrs. Check the woodruff key for proper
position and seating in the keyway. If the shaft
seal is leaking oil, repair or replace the
compressor.
Align the keyway in the rotor-pulley assembly
(2) with the woodruff key in the compressor
shaft. Slide the rotor-pulley assembly onto
the tapered shaft. Secure the rotor-pulley
assembly with the plain washer (4) and
self-locking capscrew (5). Tighten the
capscrew to a wrench torque of 15-20 ft.-lb.
(180-240 in.-lb.).
Note: The clutch can be held from rotating
by engaging the clutch with the belts
installed or by using a spanner wrench
inserted in the holes provided on the front
of the rotor-pulley hub.
6. Interference Inspection
Spin the pulley by hand and listen for
interference between the field and the
rotor-pulley. IF THERE IS INTERFERENCE,
REMOVE THE ROTOR-PULLEY ASSEMBLY
AND ADJUST THE MOUNTING OF THE
FIELD UNTIL THE INTERFERENCE
IS ELIMINATED.
4. Field Installation
Position the field assembly (1) against the
compressor bosses, aligning the field mounting
holes with the bolt holes in the bosses. Insert
the three capscrews and washers (3), furnished
with the clutch, into the bolt holes of the
compressor. Tighten the capscrews to a
wrench torque of 2 ft.-lb. (17-24 in.-lb.).
Use caution not to strip the threads in the
compressor body. Connect the field lead wires
to the vehicle wires and route them away from
moving parts.
7. Clutch Burnish
Install the belts per vehicle manufacturer
specifications. Run the engine at 2000-2500
RPM and cycle the clutch ON and OFF at
a rate of 10 to 15 times per minute for 50
cycles minimum. This procedure will help
bring the clutch up to the operating torque
capacity.
Note: To prevent electrical system
damage, use the vehicle A/C controls
to cycle the clutch.
