c. Adjust the back clearance of side gear according to the followingprocedures.
i. Insert feeler gauges (A) of the same thickness to the back of side gear from both sides, preventing side gear from falling, to
measure the clearance.
• Measure clearance 3 times by rotating side gears and take theaverage.
CAUTION:
In all 3 measurements, maximi ze the clearance by aligning
teeth on side gears at the top and bottom at the same posi-
tion.
ii. Select side gear thrust washer so that the clearance will fall within the standard.
iii. Turn differential case upside down, and measure the back clear- ance of the other side gear in the same manner.
NOTE:
Adjust the clearance to approx. 0.1 mm (0.004 in) for used differ-
ential [driven approx. 3,000 km (1864 mile) or more].
4. Install lock pin (1) to pinion mate shaft using suitable tool (A).
CAUTION:
• Do not reuse lock pin.
• Make sure that lock pin is flush with differential case.
5. Install speedometer drive gear on differential case.
6. Install output gear bearing (HR16DE engine models) or radial needle bearing (MR18DE engine models) according to the following procedures.
a. HR16DE engine models Differential side gear clearance:
