Multi-Plate Clutch

Multi-plate Clutch

REMOVAL
Remove the multi-plate clutch in the same manner as the extension case.

INSTALLATION
Install the multi-plate clutch in the same manner as the extension case.

INSPECTION
^ Inspect the drive plate facing for wear and damage.
^ Make sure the snap ring is not worn and the return spring has no permanent distortion, damage, or deformation.
^ Inspect the D-ring for damage.
^ Measure the clearance of the multi-plate clutch, and adjust so that it is within the specification range.

ADJUSTMENT
1) Remove the drive plate and driven plate from the center differential carrier.
2) Using the ST, measure distance "A", from the mating surface of the extension case to the multi-plate clutch piston.

3) Using the ST, measure height "B" from the transmission case mating surface to the end surface of the center differential clutch drum.

4) Calculation formula:
T = A - B + 0.45 mm
[T = A - B + 0.0177 in]
Initial standard: 0.2 - 0.6 mm (0.008 - 0.024 in)
Limit thickness: 1.6 mm (0.063 in)
When the usage limit is exceeded, replace the plate set (drive and driven plate), select the retaining plate of the multi-plate clutch piston, and set so that it is within the standard.
