Selection Of Driven Plate No. 3
- Install the drive plate and driven plate to the center differential carrier.
- Measure the depth "A" from the mating surface of the extension case to the transfer clutch piston.
- Using the ST, measure the height "B" from the AT main case mating surface to the end of ST.
ST 398744300 PISTON GUIDE
- Calculation formula:
When clearances are 0.2 mm (0.008 in):
T (mm) = A - (B - 50) + 0.08
[T (in) = A - (B - 1.97) + 0.0031]
When clearances are 0.6 mm (0.024 in):
T (mm) = A - (B - 50) - 0.32
[T (in) = A - (B - 1.97) - 0.0126]
T: Thickness of driven plate No. 3
A: Depth from mating surface of the extension case to the transfer clutch piston.
B: Height from AT main case mating surface to end of ST
50 mm (1.97 in): Thickness of ST
Specification:
0.2 - 0.6 mm (0.008 - 0.024 in)
NOTE: Calculation formula for "T" above is applied when measuring with the ST (398744300 PISTON GUIDE). When not using the ST,When clearances are 0.2 mm (0.008 in):
T (mm) = A - (B - α - 0.28) - 0.2
[T (in) = A - (B - α - 0.011) - 0.008]
When clearances are 0.6 mm (0.024 in):
T (mm) = A - (B - α - 0.28) - 0.6
[T (in) = A - (B - α - 0.011) - 0.024] is applied.
T: Thickness of driven plate No. 3
A: Depth from mating surface of the extension case to the transfer clutch piston.
B: Height from the AT main case mating surface to the contact face of the tool that was used as the substitute of the ST.
α: Thickness of tool used when measuring "B" 0.28 (0.011): Gasket thickness (Unit mm (in))
If it is out of specification, select the driven plate No. 3 to adjust within the specification.
- Select the driven plate No. 3 so that the clearance is within the specified range.
