REASSEMBLY SERVICE POINTS
>>A<< SPACER/SIDE 
GEAR/WASHER/PINION/PINION SHAFT 
INSTALLATION

1. Install the spacer on the back of each side gear, 

then install the side gears into the differential 
case.
NOTE: Use spacers of a medium thickness (0.93 

−

 1.00 mm) when installing new side gears.

2. Attach the washer to the back of each pinion, 

make both pinions engage with the side gears 
simultaneously, and bring the pinions into position 
while turning the gear set.

3. Insert the pinion shaft.

4. Measure the backlash between the side gears 

and pinions.

Standard value: 0.025 

− 0.150 mm

5. If the backlash is not within the standard value 

range, replace the spacers with appropriately 
selected ones and measure the backlash again.
NOTE: The amount of the backlash must be the 
same on both side gears.

>>B<<LOCK PIN INSTALLATION

Orient the lock pin as shown in the drawing.

>>C<< TAPER ROLLER BEARING
