Subaru Crosstrek Service Manual: Adjustment
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
