Inspection and Repair
Drive Plate
If the frictional surface shows signs of damage due to
excessive heat, the drive plate and pulley should be
replaced.
Pulley Assembly
Check the appearance of the pulley assembly. If the
frictional surface of the pulley shows signs of excessive
grooving due to slippage, both the pulley and drive
plate should be replaced. The frictional surfaces of the
pulley assembly should be cleaned with a suitable
solvent before reinstallation.
Coil
Check coil for loose connector or cracked insulation.
Installation
1. Install field coil.
Align the located portion (1) of the field coil and
compressor.
Tighten the mounting screw to the specified torque.
Torque: 5Nꞏm (44 lb in)
2. Connect the lead wire connector with the rubber
hold and tighten the screw.3. Install pulley assembly by using pulley installer
J-33940-A (2) and drive handle J-8092 (1).
4. Install snap ring.
5. Install shim(s).
6. Install the drive plate to the compressor drive shaft

sunk center hole of the J-33024 clutch coil installer.
Install the J-33026 through bolts and washers
through the crossbar slots and thread them into the
holding fixture J-33026 to full fixture thickness.
