CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > Reduction Drive Gear

ADJUSTMENT

1. Remove the retaining springs and reduction drive gear shims.

2. Install the transmission case, and secure it with four or five bolts.

Tightening torque:

22 N·m (2.2 kgf-m, 16.2 ft-lb)

3. Measure depth “A” from the ST upper face to the reduction drive gear end face.

ST 499575400

GAUGE

4. Raise and hold the reduction drive gear.

5. Measure depth “B” from the ST upper face to the reduction drive gear end face.

ST 499575400

GAUGE

6. Calculate the following formula.

T mm = A − B − 1.0

[T in = A − B − 0.039]

T: Moving distance of reduction drive gear shim

A: Depth from the ST upper face to the reduction drive gear end surface

B: Depth from the ST upper face to the reduction drive gear end surface

1.0 mm (0.039 in): Thickness of spring retainer
