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 selflocking
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.
