Compressor Clutch: Service and Repair

Disassembly





1. Remove the pressure plate.
a. Using SST 07110-77011 and a socket, remove the shaft nut.





b. Using SST 07112-71010 and a socket, remove the pressure plate.





c. Remove the shims from the shaft.





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





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

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





3. Remove stator.
a. Disconnect the stator lead wires from the compressor housing.





b. Using SST 07114-84020 remove the snap ring. Remove the stator.





4. Remove rotor bearings.

NOTE: Press the bearings out only if they are to be replaced.

a. Remove the bearing snap ring from the rotor.
b. Using SST 07110-77011 press out the two bearings.
5. Inspect pressure plate and rotor.
a. Inspect the pressure plate and rotor surfaces for wear and scoring. Replace if necessary.
b. Check the rotor bearings for wear and leakage of grease. Replace if necessary.

ASSEMBLY

Fig. 3 Bearing Installation Detail:

1. Install two bearings in rotor.
a. Using SST 07110-77011 press a shield ring and two new bearings into the rotor boss until it is fully seated.
b. Install the bearing snap ring into the rotor groove.





2. Install stator.
a. Install the stator on the compressor.
b. Using SST 07114-84020 install the snap ring.
c. Connect the stator lead wires to the compressor housing.





3. Install rotor.
a. Install the rotor on the compressor shaft.
b. Using SST 07114-84020 install the snap ring.





4. Install pressure plate.
a. Adjust the clearance between the pressure plate and rotor by placing shims on the compressor shaft.
Standard clearance: 0.4-0.7 mm ( 0.016-0.028 in)
If the clearance is not within tolerance, add or reduce the number of shims to obtain the standard clearance.





b. Using SST 07110-77011 and a torque wrench, install the shaft nut.
Torque: 16 Nm (12 ft lb)
