Overhaul





Inspection

1. Check the plated parts of the disc & hub assembly (A) for color changes, peeling or other damage. If there is damage, replace the clutch set.
2. Check the pulley (B) bearing play and drag by rotating the pulley by hand. Replace the clutch set with a new one if it is noisy or has excessive play/drag.




3. Measure the clearance between the pulley (B) and the disc & hub assembly (A) all the way around. If the clearance is not within specified limits, remove the disc & hub assembly and add or remove shim (gap washer) as needed to increase or decrease clearance.

Clearance:0.45 ± 0.1mm (0.018 ± 0.004 in.)

NOTE:
The shims (gap washers) are available in seven thicknesses: 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm and 1.3mm.




4. Check operation of the magnetic clutch.
Connect the compressor side terminals to the battery (+) terminal and the ground battery (-) terminal to the compressor body.Check the magnetic clutch operating noise to determine the condition.






Disassembly

1. Remove the center bolt (A) while holding the disc & hub assembly with a commercially available disc & hub assembly bolt remover; Special tool number 09977-29000.

Tightening torque :
10 - 15N.m (1.02 - 1.53kgf.m, 7.37 - 11lb-ft)




2. Remove the disc & hub assembly (A) and shim (gap washer) (B), taking care not to lose the shims. If the clutch needs adjustment, increase or decrease the number and thickness of shims as necessary, then reinstall the disc & hub assembly, and recheck its clearance.




3. If you removal the field coil, remove retainer ring (A) with retainer ring pliers.

NOTE:
- Be careful not to damage the pulley (B) and compressor during removal/installation.
- Once retainer ring (A) is removed, replace it with a new one.




4. Remove the screw (A) from the field coil ground terminal. Remove the retainer ring (B) and then remove the field coil (C) from the shaft with a puller. Be careful not to damage the coil and compressor.




5. Reassemble the compressor clutch in the reverse order of disassembly, and note these items :
A. Clean the pulley and compressor sliding surfaces with non-petroleum solvent.
B. Install new retainer rings, and make sure they are fully seated in the groove.
C. Make sure that the pulley turns smoothly after its reassembled.
