Selection Of Driven Plate No. 3
WARNING: This page is about a different variant/trim than selected.
- 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 multi-plate clutch (LSD) piston.
- Using the ST, measure the height "B" from the AT main case mating surface to end of ST, and then subtract the thickness of ST (piston guide) (50 mm (1.97 in)) from measured value.
ST 398744300 PISTON GUIDE
- Calculation formula:
When clearances are 0.2 mm (0.008 in):
T (mm) = A - B + 0.08
[T(in) = A-B + 0.0031]
When clearances are 0.6 mm (0.024 in):
T (mm) = A - B - 0.32
[T (in) = A- B- 0.0126]
T: Thickness of driven plate No. 3
A: Depth from mating surface of extension case to multi-plate clutch (LSD) piston
B: Height from AT main case mating surface to end of ST
Standard: 0.2 - 0.6 mm (0.008 - 0.024 in)
NOTE: Calculation formula for "T" is applied when measuring using ST (398643600 GAUGE, 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 extension case to multi-plate clutch (LSD) 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.THICKNESS CHARTDriven plate No. 3 Part number Thickness mm (in) 31589AA041 1.6(0.063) 31589AA050 2.0 (0.079) 31589AA060 2.4 (0.094) 31589AA070 2.8(0.110)
