Multi-Plate Clutch: Adjustment

Remove drive plate and driven plate from center differential carrier.

Using the special tool, measure distance "A" from extension case joining surface to multi -plate clutch (LSD) piston.

A: Measured value
Using ST, measure height "B" from transmission case joining edge to center differential clutch drum edge.

B: Measured value

Calculation formula

T = A - B + 0.45 mm

[T = A - B + 0.0177 in]

NOTE:

Calculation formula for "T" is applied when measuring using ST (32005073 GAUGE, 32005076 GAUGE). When not using ST, apply
T = (A - a + 0.45 mm) - (B - b)

[T = (A - a + 0.0177 in) - (B - b)].

T: Thrust needle bearing thickness

A: Distance from end of extension case to end of reduction drive shaft

B: Distance from end of transmission case to end of rear drive shaft

a: Collar thickness used when measuring "A"

b: Collar thickness used when measuring "B"

0.45: Gasket thickness (mm)
Measure multi-plate clutch (LSD) driven and drive plate thickness to find the clearance between measurement value and "T".
Standard value:

0.2 - 0.6 mm (0.008 - 0.024 in)

Limit value:

1.6 mm (0.063 in)

If outside the standard value, replace the plate set (drive and driven plate). Select a multi-plate clutch (LSD) piston side adjustment plate that will bring clearance within the standard value.
