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 filler gauge.

Clutch air gap : 0.0138 - 0.0256 in (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.
