4. Position center pulley puller on the end of drive shaft, and
remove pulley assembly using any commercially available pul-
ley puller.
To prevent pulley groove from being deformed, puller claws
should be positioned into edge of the pulley assembly.
5. Remove field coil harness clip using a pair of pliers.
6. Remove snap ring using external snap ring pliers.
Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check appearance of pulley assembly. If contact surface of pulley
shows signs of excessive grooving, replace clutch disc and pulley.
Contact surfaces of pulley assembly should be cleaned with a suit-
able solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.

INSTALLATION
1. Install field coil.
Be sure to align coil’s pin with hole in compressor’s front head.
2. Install field coil harness clip using a screwdriver.
3. Install pulley assembly using pulley installer (SST) and a hand press, and then install snap ring using snap ring pliers.
4. Install clutch disc on drive shaft, together with original shim(s). Press clutch disc down by hand.
5. Using holder to prevent clutch disc rotation. After tightening bolt, make sure pulley rotates smoothly.

6. Check clearance around entire periphery of clutch disc.
If specified clearance is not obtained, replace adjusting spacer
and readjust.
Break-in Operation
When replacing compressor clutch assembly, always carry out break-in operation. This is done by engaging
and disengaging the clutch about thirty-times. Break-in operation raises the level of transmitted torque. Disc to pulley clear-
ance : 0.25 - 0.6 mm (0.010 - 0.024 in)
