Compressor Clutch: Adjustments

A/C CLUTCH AIR GAP
1. Check air gap between A/C clutch and A/C clutch pulley mating surfaces in three locations equally spaced around A/C clutch pulley. Record air gap measurements.
2. Rotate A/C clutch pulley one-half turn (180 degrees) and again check air gap in three equally spaced locations. Record air gap measurements.
3. The smallest air gap measurement must be within specified limits for air gap. Add, remove or replace shims between A/C clutch and compressor shaft end as necessary until smallest air gap is within 0.4-0.7 mm (0.016-0.027 inch).
