Front Reduction Driven Gear: Adjustment

If the ball bearing is attached, remove the ball bearing and front reduction driven gear shim (front side). Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>Converter Case Cover>REMOVAL .
Using the ST, measure height "A" from the ST upper face to the converter case mating surface.

Install a new ball bearing to the reduction driven gear.
Measure depth "C" from the ST upper face to the ball bearing end face using the ST.

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 ball bearing catch surface

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

15 mm (0.591 in): Thickness of ST

Clearance "T" mm (in)	Front reduction driven gear shim (front side) thickness mm (in)
0.470 - 0.569 (0.019 - 0.021)	0.4 (0.016)
0.570 - 0.669 (0.022 - 0.025)	0.5 (0.020)
0.670 - 0.769 (0.026 - 0.029)	0.6 (0.024)
0.770 - 0.869 (0.030 - 0.033)	0.7 (0.028)
0.870 - 0.980 (0.034 - 0.039)	0.8 (0.031)

Select one to two front reduction driven gear shims (front side) so that the front reduction driven gear shim (front side) thickness meets the value obtained from the above.
