Compressor Clutch: Testing and Inspection




1. INSPECT COOLER COMPRESSOR ASSEMBLY
a. Disconnect the cooler compressor assembly connector.
b. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to the body ground.
c. Check that the magnetic clutch is engaged.

If the operation is not as specified, replace the magnet clutch assembly.


2. INSPECT MAGNETIC CLUTCH CLEARANCE




a. Set the dial indicator to the magnet clutch hub.
b. Connect the battery positive lead to the terminal of the magnet clutch connector and the negative lead to the earth wire. Turn the magnet clutch on and off and measure the clearance.

Standard clearance: 0.35 to 0.60 mm (0.014 to 0.023 in.)

If the measured value is not within the standard range, remove the magnet clutch hub and adjust it with magnet clutch washers.

NOTE: Adjustment shall be performed with 3 or less magnet clutch washers.

c. Remove the compressor and magnetic clutch from the vise.
