3) Install the ball bearing on reverse side with the
same procedure in step 2).
E: INSPECTION
Make sure the ball bearing and gear are not de-
formed or damaged.
F: ADJUSTMENT
1) Using depth gauge, measure depth "A" from
mating surface of extension case to ball bearing on
rear end of reduction driven gear.
A
2) Using a depth gauge, measure the height "B"
from mating surface of extension case to ball bear-
ing inside low part of extension case.
3) Calculation formula:
Select the ball bearing from the table to adjust
clearances within 0.05 — 0.25 mm (0.0020 —
0.098 in).
When clearances are 0.05 mm (0.0020 in):
T (mm) = A " B + 0.23
[T (in) = A " B + 0.0091]
When clearances are 0.25 mm (0.0098 in):
T (mm) = A " B + 0.03
[T (in) = A " B +0.0011]
