Adjusting clutch clearance

Adjusting clutch clearance

The specified clearance between hub and pulley should be 0.5 ± 0.15 mm. Proceed as follows to check clutch clearance.

Rest plate 1895655000 on hub surface.

Use a gauge to measure the gap between the plate and the lower part of the clutch (gap X).

Excite solenoid with a voltage of 12V and use gauge to measure the gap between the plate and the bottom part of the clutch (gap Y).

Clutch clearance is equal to: X – Y.

If the measurement obtained is not as specified, add or remove shims between hub and compressor shaft.

For this purpose, shims are available in the following thicknesses: 0.10 - 0.30 - 0.50 mm.

After adjusting the clutch clearance, tighten the bolt retaining the assembly to the compressor shaft to a torque of: 10.8 - 16.2 Nm
