Front Reduction Driven Gear: Adjustment

If the ball bearing is attached, remove the bearing and shims. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>Converter Case Cover>REMOVAL .
Using the ST, measure height "A" from the ST upper face to the mating surface of the case.

Calculate clearance "T" using the following formula.

Formula: T mm = (C - 15) - ((A - 15) - B)

[T in = (C - 0.591) - ((A - 0.591) - B)]

T: Clearance

A: Height from the ST upper face to the converter case mating surface

B: Depth from the converter case cover upper face to the bearing catch surface

C: Depth from the ST upper face to the bearing end face

15 mm (0.591 in): Thickness of ST

Select one to two shims so that the total thickness meets the value obtained from above.
