Step 1
Position the field assembly (1) against the
compressor bosses, aligning the field mounting
holes with the bolt holes in the bosses. Insert
four capscrews and lockwashers (3) furnished
with the clutch into the bolt holes of the
compressor. Tighten the capscrews to a wrench
torque of 7 - 10 ft./lbs. (85 - 120 in./lbs.). Use
caution not to strip the threads in the
compressor body.
Step 2
The compressor shaft must be clean and free
from burrs. Check the woodruff key for proper
position and seating.
Step 3
Slide the rotor pulley assembly (2) on to the
tapered shaft (aligning the keyway with the
woodruff key in the shaft). Secure the rotor
pulley assembly with the washer (4) and self-
locking capscrew (5) provided with the clutch.
Tighten the self-locking capscrew to a wrench
torque of 15 - 20 ft./lbs. (180 - 240 in./lbs.).
Step 4
Rotate the pulley assembly manually to assure
that there is no interference between the field
and rotor. If any interference occurs, a rubbing
noise can be heard as the pulley rotates. In case
of rubbing or other mechanical interference,
disassemble the clutch and repeat the
installation of the field assembly.
Step 5
To disassemble the rotor-pulley assembly from
the compressor, remove the self-locking
capscrew and washer and insert a 5/8-11 UNC-
2B capscrew in the threaded portion of the hub.
The pressure exerted by the capscrew on the
end of the compressor shaft will force off the
rotor pulley assembly without damage to the
clutch or compressor.
Do not use a wheel
puller on the outer diameter of the pulley, as this
can result in damage to the clutch bearing.
Warranty voided if clutch is removed from shaft
without using a 5/8-11 UNC bolt in the hub.
Step 6
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.
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.
