Compressor Clutch: Adjustments
MAGNETIC CLUTCH ADJUSTMENT1. Set the A/C compressor on a level block.
2. Turn on the magnetic clutch by connecting the B+ 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 points 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 (0.2 mm {0.008 in}, 0.5 mm {0.02 in}) or the number of shims.
Clearance: 0.4 - 0.6 mm {0.016 - 0.023 in}
