- Pulley removal:
Use a pulley puller with small adapter. Position the small adapter on the end of the drive shaft and the center of the puller on the small adapter. Remove the pulley assembly with the puller.
To prevent deformation of the pulley groove, the puller claws should be hooked under (not into) the pulley groove.

Be sure to align the magnet coil pin with the hole in the compressor front head.

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




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




- Using the clutch disc tool to prevent clutch disc rotation, tighten the bolt to 12 N.m (1.2 kg-m, 9 ft-lb).
- After tightening the bolt, check that the pulley rotates smoothly.




- Check clearance all the way around the clutch disc.
Clutch disc-to-pulley : 0.3 - 0.6 mm (0.012 - 0.024 in) clearance
If the specified clearance is not obtained, replace adjusting spacer and readjust.

BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the break-in operation. This is done by engaging and disengaging the clutch about 30 times. Break-in operation raises the level of transmitted torque.
