A/C Compressor Clutch Air Gap

If a new clutch plate and/or clutch pulley are being used, the air gap between the clutch plate and clutch pulley must be checked using the following procedure:
1. Using feeler gauges, measure the air gap between the clutch plate and the clutch pulley friction surfaces
2. If the air gap is not between specifications, add or subtract shims until the desired air gap is obtained

NOTE: The shims may compress after tightening the compressor shaft bolt. Check the air gap in four or more places on the clutch plate to verify that the air gap is still correct. Spin the clutch pulley before making the final air gap check.
