Clutch Plate Gap, Checking

A/C Clutch -N25- (Sanden), Removing And Installing

Clutch plate gap, checking






- Gap: 0.4...0.6 mm (0.015...0.023 in)

Determining "Dimension 1"
- Using depth gauge -1-, measure gap between top of clutch plate -3- and pulley - 2- at three equally spaced locations (measurement must not deviate). Note result.

Determining "Dimension 2"
- If compressor is installed in vehicle, disconnect electrical connector -4- from vehicle wiring harness.
- Using a jumper wire, energize the clutch coil by applying 12 V (B+) to connector -4-. If compressor is removed from vehicle, compressor must be grounded.
- With clutch energized, measure gap between belt pulley -2- and clutch plate -3- with depth gauge -1-. Note result.

The allowable gap (0.4... 0.8 mm) is the difference between "Dimension 1" and "Dimension 2".


NOTE:
- Gap must be within tolerance around entire circumference.
- If the gap is outside the permitted tolerance range, remove clutch plate and adjust gap by adding or removing shims.
