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. Check the contact surface for any sign of excessive grooving due to slippage. If any sign is found, replace both the pulley and clutch disc. The contact surfaces of the pulley assembly should be cleaned with a suitable solvent before reinstallation.





Coil

Check coil for loose connections 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 a suitable tool, then install the snap ring using snap ring pliers.





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





^ Using the holder to prevent clutch disc rotation, tighten the bolt to 10 ft. lb (14 N.m, 1.4 kg-m) torque.





^ Check clearance around the entire periphery of the clutch disc.

Disc-to-pulley clearance

0.12 - 0.024 in. (0.3 - 0.6 mm)

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

Break-in operation

When replacing the compressor clutch assembly, always conduct 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.
