Compressor Clutch: Adjustments
MAGNETIC CLUTCH ADJUSTMENT1. 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 measuring probe onto 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.
6. Verify that the clearance is within the specification.
- If not within the specification, remove the pressure plate and adjust the clearance by changing the shim from 0.2 mm (0.008 in) to 0.5 mm (0.02 in) or the number of shims.
Clearance 0.4 - 0.6 mm (0.016 - 0.023 in).
