Multi-Plate Clutch

NOTE: The content of this article/image reflects the changes called out by TSB 18-88-05.

Multi-plate Clutch

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

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

INSPECTION
^ Check the drive plate facing for wear and damage.
^ Check the snap ring for wear, and the return spring for permanent set, breakage and deformation.
^ Inspect lathe cut seal ring for damage.
^ Measure the multi-plate clutch clearance and adjust to within specifications.

ADJUSTMENT
1) Install the drive plate and driven plate to center differential carrier.





2) Using the ST, measure the distance "A" from the end surface of ST to multi-plate clutch piston. ST 398643600 GAUGE






3) Using the ST, measure the height "B" from the mating surface of transmission case to the end surface of ST. ST 398744300 GAUGE


4) 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 (398643600 GAUGE, 398744300 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 the end surface of collar as substitute for ST to multi-plate clutch piston
B: Distance from the mating surface of transmission case to the end surface of collar as substitute for ST
a: Collar thickness used when measuring "A"
b: Collar thickness used when measuring "B"
0.45: Gasket thickness (mm)

Measure multi-plate clutch driven and drive plate thickness to find the clearance between the measured value and "T".

Standard: 0.2 - 0.6 mm (0.008 - 0.024 inch)
Service limit: 1.6 mm (0.063 inch)





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