2) Using the ST, measure distance "A" from the
end of the ST to the rear drive shaft ball bearing
outer ring mating surface.

4) Calculation formula:
Calculation of "T":
When the clearance is 0.05 mm (0.0020 in), select
up to 4 adjustment shims to meet the clearance val-
ue from the table.
When the clearance is 0.05 mm (0.0020 in)
T = A – B + 0.40 mm
[T = A – B + 0.0157 in]
When the clearance is 0.25 mm (0.0098 in)
T = A – B + 0.20 mm
[T = A – B + 0.0079 in]
T: Shim clearance
A: Distance from the ST end face to the rear drive
shaft ball bearing outer ring contact face.
B: Distance from the mating surface of the trans-
mission case to the end of the ST
T: Shim thickness
0.05 — 0.25 mm (0.0020 — 0.0098 in)
