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
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 inch]

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 - P)
[T = (A - a + 0.0177 inch) - (B - P)]
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 (0.0177): Gasket thickness (mm (in))
^ Measure multi-plate clutch 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)

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