Compressor Clutch: Adjustments

1. Remove and set the A/C compressor on a level block.
2. Turn ON the magnetic clutch by connecting the battery positive voltage to the magnetic clutch connector terminal and the ground to the A/C compressor body.




3. Fix a dial gauge on a magnetic base and set the probe onto measuring point A on the pressure plate surface.
4. Turn OFF the magnetic clutch by disconnecting the ground from the A/C compressor body, then measure the dial gauge readings.




5. Measure the clearance for point B and C on the pressure plate surface by repeating the above steps 2 through 4.

Clearance
0.35 - 0.65 mm (0.014 - 0.025 in)




6. If not within the specification, remove the pressure plate and adjust the clearance by changing the shim size or the number of shims.
