Determining "Dimension 2"

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

Notes:

Gap: 0.4...0.6 mm

(0.015...0.023 in)

- 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.

- If compressor is installed in

vehicle, disconnect electrical
connector -4- from vehicle wiring
harness.

- Using a jumper wire, energize the

clutch coil by applying 12V (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.

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
