Beetle L4-1.9L DSL Turbo (ALH) (1998)
Clutch plate gap, checking
-
Gap: 0.4 - 0.8 mm (0.015 - 0.023 in)
Determine "Dimension 1"
-
Using depth gauge -1-, measure gap between top of clutch plate -3- and clutch pulley -2- at three equally spaced locations (measurement must not
deviate).
Determine "Dimension 2"
-
If compressor is installed in vehicle, disconnect compressor electrical connector -4- from vehicle wiring harness.
-
Using a jumper wire, energize the clutch coil by applying 12V to connector -A- (battery terminal B+). If compressor is removed from vehicle,
compressor must be grounded.
-
With clutch energized, measure gap between pulley -2- and clutch plate -3- with depth gauge -1-.
The allowable gap (0.4 - 0.8 mm / 0.015 - 0.023 in) is the difference between "Dimension 1" and "Dimension 2".
NOTE:
-
Gap must be within tolerance around entire circumference.
-
If gap is outside the permitted tolerance range, remove clutch plate and adjust gap by adding or removing shims. Refer key-3- See: A/C Clutch -
