Compressor Clutch: Testing and Inspection

MAGNETIC CLUTCH

CHECKING THE CLUTCH AIR GAP

1. Check the air gap between the clutch hub and pulley contact surface using a tiller gauge.

Clutch air gap : 0.35 - 0.65 mm

2. Check the gap around the pulley at 3 points.




3. If the clutch air gap is outside the normal range, correct it using a shim of proper size.
