PINION SHAFT INSTALLATION
AK300655
1. Mount a spacer on the back surface of the side
gear, and then install the side gear in the
differential case.
NOTE: When a new side gear is to be installed,
use a medium thickness spacer (0.93 to 1.00
mm).
2. Set the washer on the back of each pinion, and
put both pinions simultaneously in mesh with the
side gears. While rotating them, install them into
position.
AK300656
3. Insert the pinion shaft.
AK300657
4. Measure the backlash between the side gear and
pinion.
Standard value:
0.025
− 0.150 mm
5. If the backlash is out of the standard value, select
a spacer and re-measure the backlash.
NOTE: Adjust until the backlash on both sides are
equal.
