T: Shim thickness
A: Depth from end of extension case to ball bearing
outer ring contact surface
B: Height from end of intermediate case to ball
bearing outer ring contact surface
α: Tool thickness used when measuring "A"
β: Tool thickness used when measuring "B"

2. SELECTION OF DRIVEN PLATE No. 3
1) Install the drive plate and driven plate to center
differential carrier.
2) Measure the depth "A" from the mating surface
of extension case to multi-plate clutch (LSD) piston.
A
3) Using the ST, measure the height "B" from the
intermediate case mating surface to end of ST, and
then subtract the thickness of ST (piston guide) (50
mm (1.97 in)) from measured value.

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 mating surface of intermediate case
to end surface of ST
Specification:
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 ST, apply follow-
ing.
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]
T: Thickness of driven plate No. 3
A: Depth from mating surface of extension case to
multi-plate clutch (LSD) piston
B: Height from mating surface of intermediate case
to end surface of tool as substitution for ST
α: Tool thickness used when measuring "B"
