Compressor Clutch: Service and Repair

MAGNETIC CLUTCH DISASSEMBLY

1. REMOVE PRESSURE PLATE




a. Using SST and a socket wrench, remove the shaft bolt.
Torque: 14 N.m (140 kgf.cm, 7 ft.lbf)
SST 07112-76060




b. Install SST on the pressure plate.
SST 07112-66040




c. Using SST and a socket wrench, remove the pressure plate.
SST 07112-76060




d. Remove the shims from the pressure plate.

2. REMOVE ROTOR




a. Using SST, remove the snap ring.
SST 07114-84020

ASSEMBLY CAUTION: Do not spread the point of SST too wide.

Max width:
23.1 mm




NOTE: The snap ring should be installed so that its beveled side faces up.




b. Using a plastic hammer, tap the rotor off the shaft.

NOTE: Be careful not to damage the pulley when tapping on the rotor.

3. REMOVE STATOR




a. Disconnect the stator lead wire from the compressor housing.




b. Using SST, remove the snap ring.
SST 07114-84020




NOTE: The snap ring should be installed so that its beveled side faces up.




c. Remove the stator.

MAGNETIC CLUTCH ASSEMBLY
Assembly is in the reverse order of disassembly.

CHECK CLEARANCE OF MAGNETIC CLUTCH





a. Set the dial indicator to the pressure plate of the magnetic clutch.
b. Connect the magnetic clutch lead wire to the positive (+) terminal of the battery.
c. Check the clearance between the pressure plate and rotor, then connect the negative (-) terminal of the battery.
Standard clearance:
0.5 ± 0.15 mm (0.020 ± 0.0059 in.)
If the clearance is not within standard clearance. adjust it using shims to obtain the standard clearance.

Shim thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020 in.)
