REMOVAL







- When removing center bolt, hold clutch disc with clutch disc wrench.




- Remove the clutch disc using the clutch disc puller.
Insert the holder's three pins into the holes in the clutch disc. Rotate the holder clockwise to hook it onto the plate. Then, tighten the center bolt to remove the clutch disc.

After removing the clutch disc, remove the shims from either the drive shaft or the clutch disc.




- Remove the snap ring using external snap ring pliers.




- Pulley removal
Position the center pulley puller on the end of the drive shaft, and remove the pulley assembly using any commercially available pulley puller.

To prevent the pulley groove from being deformed, the puller claws should be positioned onto the edge of the pulley assembly.




- Remove the field coil harness clip using a pair of pliers.




- Remove the 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 the appearance of the pulley assembly. If the contact surface of pulley shows signs of excessive grooving, replace clutch disc and pulley. The contact surfaces of the pulley assembly should be cleaned with a suitable solvent before reinstallation.

Coil
Check coil for loose connection or cracked insulation.

INSTALLATION



- Install the field coil.
Be sure to align the coil's pin with the hole in the compressor's front head.
- Install the field coil harness clip using a screwdriver.




- Install the pulley assembly using the installer and a hand press, and then install the snap ring using snap ring pliers.




- Install the clutch disc on the drive shaft, together wit the original shim(s). Press the clutch disc down by hand.




- Using the holder to prevent clutch disc rotation, tighten the bolt to 14 Nm (1.4 kg.m, 10 ft.lb) torque.
After tightening the bolt, check that the pulley rotates smoothly.




- Check clearance around the entire periphery of clutch disc.
Disc-to-pulley clearance:
0.3 - 0.6 mm (0.012 - 0.024 in)

If the specified clearance is not obtained, replace adjusting spacer and readjust.

Break-in Operation
When replacing compressor clutch assembly, always carry out the break-in operation. This is done by engaging and disengaging the clutch about thirty times. Break-in operation raises the level of transmitted torque.
