Reduction Driven Gear: Adjustment

Using depth gauge, measure depth "A" from mating surface of extension case to ball bearing on rear end of reduction driven gear.

Using a depth gauge, measure the height "B" from mating surface of extension case to ball bearing inside low part of extension case.

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]

T: Shim clearance

A: Depth from mating surface of extension case to ball bearing outer ring end surface

B: Height from mating surface of extension case to ball bearing inside low part
