3. Remove speedometer drive gear from differential case.
4. Drive out lock pin from differential case (1) using Tool (A).
5. Draw out pinion mate shaft.
6. Remove pinion mate gears, pinion mate gear thrust washers, side gears and side gear thrust washers.
INSPECTION
Gears, Washers, Pinion Mate Shaft and Differential Case • Check mating surfaces of differential case, side gears, pinion mate gears and pinion mate shaft. Replace if necessary.
• Check washers for wear. Replace if necessary.

REPAIR FOR COMPONENT PARTS
• Make sure bearings roll freely and are free from noise, cracks, pit- ting or wear. Replace if necessary.
CAUTION:
When replacing taper roller b earing, replace outer and inner
race as a set.
ASSEMBLY
1. Attach side gear thrust washers to side gears, then install pinion mate thrust washers and pinion mate gears in place.
CAUTION:
Apply ATF to any parts.
2. Insert pinion mate shaft. CAUTION:
• When inserting, be careful not to damage pinion mate gear thrust washers.
• Apply ATF to pinion mate shaft.
3. Select side gear thrust washers according to the following procedures.
a. Place differential case in the upright position so that the side gear to be measured is at the top.
(A): Location for inserting feeler gauge
(B): Side gear tooth
(C): The center line of differential case
b. In order to maximize the back clearance, rotate side gears so that a tooth on side gears at the top and bottom will align at the
same position as shown. SPD715

c. Adjust the back clearance of side
gear according to the following
procedures.
i. Insert feeler gauges (A) of the same thickness to the back of side gear from both sides, prevent ing side gear from falling, to
measure the clearance.
• Measure clearance 3 times by rotating side gears and take the
average.
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:

1. Drive each differential side oil seal evenly using Tools (Tran- saxle case side) and suitable tool (Convertor housing side) so
that differential side oil seal protrudes by the dimension (C) or
(D) respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)
NOTE:
Differential side oil seal pulling direction is used as the reference.
2. Install O-ring on governor cap. CAUTION:
• Do not reuse O-ring.
• Apply ATF to O-ring.
3. Install governor cap in transaxle case.
4. Install snap ring in transaxle case.
5. Install parking actuator support (1) on transaxle case. (A): Inside
(B): Outside
CAUTION:
Be careful with the direction of parking actuator support (1).
6. Tighten parking actuator support bolts to the specified torque. Refer to AT-236, " Component " .
7. Install parking pawl (2) on transaxle case, and fix it with parking shaft (1).Tool numbers : ST35325000 ( — )

• Measure dimension (C) between the surface of idler gear
bearing inner race and the surface of transaxle case.
• Measure dimension (C) in at least two places, and take the
average.
• Remove reduction pinion gear from transaxle case.
• Measure dimension (D) between the end of reduction pinion gear and the adjusting shim mating surface of reduction pinion
gear.
• Measure dimension (D) in at least two places, and take the
average.
• Calculate dimension (A).
e. Measure dimension (E) between the end of idler gear and idler gear bearing inner race mating surface of idler gear.
• Measure dimension (E) in at least two places, and take the
average.
f. Select proper thickness of reduction pinion gear adjusting shim. Refer to AT-373, " Adjusting shims, Needle Bearings, Thrust
Washers and Snap Rings " for reduction pinion gear adjusting
shim selection.
2. Install reduction pinion gear and reduction pinion gear adjusting shim selected in step 1-f on transaxle case.
CAUTION:
Apply ATF to reduction pinion gear bearing.
3. Press idler gear bearing inner race on idler gear.
4. Press idler gear on reduction pinion gear using Tool.
CAUTION:
• Apply ATF to idler gear bearing.
• Press idler gear until idler gear fully contacts reduction
pinion gear bearin g adjusting shim.
5. Set manual shaft in “P” position to lock idler gear.
6. Tighten lock nut of idler gear to the specified torque. Refer to AT-236, " Component " .
CAUTION:
Lock idler gear with parking pa wl when tightening lock nut.
