AUTOMATIC TRANSMISSION
4) Calculation formula:
NOTE:
Calculate "T":
When the clearances are 0.05 mm (0.0020 in), se-
lect up to four adjusting shims from the table, suit-
able for clearance value.
When clearances are 0.05 mm (0.0020 in)
T = A − B + 0.40 mm
[T = A − B + 0.0157 in]
When clearances are 0.25 mm (0.0098 in)
T = A − B + 0.20 mm
[T = A − B + 0.0079 in]
T: Shim clearance
A: Depth from mating surface of extension case to
rear drive shaft ball bearing outer ring contact sur-
face
B: Height from mating surface of transmission case
to ball bearing end of rear drive shaft
T: Shim thickness
0.05 — 0.25 mm (0.0020 — 0.0098 in)
Example:
When A = 90.50 mm (3.5630 in), B = 90.35 mm
(3.5571 in)
Calculation when clearance is 0.05 mm (0.0020 in)
T = 90.50 − 90.35 + 0.4 = 0.55
[T = 3.5630 − 3.5571 + 0.0157 = 0.0216]
Calculation when clearance is 0.25 mm (0.0098 in)
T = 90.50 − 90.35 + 0.2 = 0.35
[T = 3.5630 − 3.5571 + 0.0079 = 0.0138]
NOTE:
Calculation formula for "T" above is applied when
measuring using ST (398643600 GAUGE). When
not using the ST,
T = (A − α + 0.45 mm) − (B − β) − H
[T = (A − α + 0.0177 in) − (B − β) − H]
is applied.
T: Thrust needle bearing thickness
A: Depth from mating surface of extension case to
rear drive shaft ball bearing outer ring contact sur-
face
B: Height from mating surface of transmission case
to rear drive shaft ball bearing end surface
α: Tool thickness used when measuring "A"
β: Tool thickness used when measuring "B"
0.45: Gasket thickness (mm)
H: Shim clearance
After calculation, the value of "T" becomes between
0.35 mm (0.0138 in) and 0.55 mm (0.0216 in),
therefore select two shims with thickness of 0.2 mm
(0.010 in) or one shim with thickness of 0.5 mm
(0.020 in).
