Multi - Plate Clutch

Multi - Plate Clutch
REMOVAL
Remove multi-plate clutch following the same instructions as for the extension case.

INSTALLATION
Install multi-plate clutch following the same instructions as for the extension case.

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

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.

ST 32005073 GAUGE





A: Measured value
Using ST, measure height B from transmission case joining edge to center differential clutch drum edge.
ST32005076 GAUGE





B: Measured value
Calculation formula T6: A - B + 0.45 mm
T = A - B + 0.0177 inch]

Note:
^ Calculation formula for T6: 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 inch) - (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 inch)
Limit value: 1.6 mm (0.063 inch)

Obtainable driven plate:

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.
