CautionWhen installing a new side gear, use a spacer of
medium thickness
[0.93 - 1.00 mm (.036 - .04 in.)].
(2) Set the washer on the back of each pinion and insert the
two pinions to specified position while engaging themwith the side gears and turning them.
(3) Insert the pinion shaft.
(4) Measure the backlash between the side gears and
pinions.Standard value: 0.025
- 0.150 mm (.OOl - .006 in.)
(5) If the backlash is out of specification, disassemble againand using correct spacer, reassemble and adjust.
CautionAdjust for same backlash of both side gears.
4. INSTALLATION OF LOCK PIN
Align the pinion shaft lock pin hole with the case lock pin
hole and insert the lock pin.
