Transfer Clutch
AUTOMATIC TRANSMISSION
4) 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 measur-
ing 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 –
D – 0.28) – 0.2
[T (in) = A – (B –
D – 0.011) – 0.008]
When clearances are 0.6 mm (0.024 in):
T (mm) = A – (B –
D – 0.28) – 0.6
[T (in) = A – (B –
D – 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.
D: 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.
