Front Reduction Driven Gear: Adjustment
WARNING: This page is about a different variant/trim than selected.
- If the ball bearing is attached, remove the bearing and shims. Refer 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.
ST 398643600 GAUGE - Measure depth "B" from the converter case cover upper face to the bearing catch surface.
- Install the ball bearing to the reduction driven gear.NOTE: Use a new ball bearing.
- Measure depth "C" from the ST upper face to the bearing end face using the ST.
ST 398643600 GAUGE - 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
