Differential and Drive Pinion
COMPONENT PARTS INSTALLATIONDisassembly, inspection and assembly of each component group have been indicated in the preceding chapter. Before assembly, make sure, again, that all component groups are assembled correctly. If something wrong is found in a certain component group during assembly, inspect and repair this group immediately.
Recommended ATF: D-II or DEXRON(R) III (DEXRON(R) II)
GENERAL INSTALLATION NOTES:
a. The automatic transaxle is composed of highly precision-finished parts, necessitating careful inspection before assembly because even a small nick could cause fluid leakage or affect performance.
b. Before assembling new clutch discs, soak them in automatic transaxle fluid for at least 15 minutes.
c. Apply automatic transaxle fluid on the sliding or rotating surfaces of parts before assembly.
d. Use petroleum jelly to keep small parts in their places.
e. Do not use adhesive cements on gaskets and similar parts.
f. When assembling the transaxle, be sure to use new gaskets and O-rings.
g. Dry all parts with compressed air-never use shop rags.
h. Be sure to install the thrust bearings and races in the correct direction and position.
DIFFERENTIAL AND DRIVE PINION INSTALLATION
1. INSTALL DRIVE PINION INTO TRANSAXLE CASE
a. Using Special Service Tool(SST), install the bearing to the drive pinion shaft.

b. Place the bearing cage onto the drive pinion shaft.
NOTICE: Be careful not to damage the oil seals with the pinion shaft.
c. Using a brass bar and hammer, slightly tap the bearing cage into the transaxle case until the snap ring groove in the bore can be seen.
d. Using SST, install snap ring into the bore.
SST 09350-32014(09351-32050)
e. Using SST, install the snap ring.
SST 09350-32014(09351-32050)
2. PLACE OIL SLINGER AND NEW SPACER
HINT: Install the spacer with the small end downward.
3. INSTALL OUTER RACE TO TRANSAXLE CASE
Using SST, press in the outer race.
SST 09350-32014(09351-32100, 09351-32140)
4. INSTALL COUNTER DRIVE GEAR
a. Place a brass bar into the transaxle hole to hold the drive pinion shaft.
b. Using SST, press in the counter driven gear until the counter driven gear bearing almost touches the counter gear.
SST 09350-32014(09351-32140)
5. INSTALL NEW LOCK NUT AND ADJUST DRIVE PINION PRELOAD
a. Install the new lock nut.
b. Using SST to hold the gear, tighten the nut.
SST 09330-00021, 09350-32014(09351-32032)
Torque: 280 Nm (2,855 kgf.cm, 206 ft. lbs.)
c. Turn the gear counterclockwise and clockwise several times.
d. Using a small torque wrench, measure the preload of the drive pinion.
Drive pinion preload (at starting):
New bearing: 1.0 - 1.6 Nm (10 - 16 kgf.cm, 8.7 - 13.9 inch lbs.)
Reused bearing: 0.5 - 0.8 Nm (5 - 8 kgf.cm, 4.3 - 6.9 inch lbs.)
- If the preload is greater than specified, replace the bearing spacer.
- If the preload is less then specified, retighten the nut 13 Nm (130 kgf.cm, 9 ft. lbs.) at a time until the specified preload is reached.
If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat the preload procedure.
Do not back off the nut to reduce the preload.
Maximum torque: 353 Nm (3,600 kgf.cm, 260 ft. lbs.)
e. If the preload is adjusted within specification, make a note of it.
f. Stake the lock nut.
6. INSTALL APPLY GASKET
7. PLACE OUTER RACE AND SHIM ONTO RIGHT-HAND SIDE BEARING
8. PLACE DIFFERENTIAL CASE INTO TRANSAXLE CASE
Be sure to install the shim and outer race into place.
9. INSTALL CARRIER COVER
a. Remove any packing material and be careful not to drop oil on the contacting surfaces of the carrier cover and transaxle case.
b. Apply seal packing to the carrier cover.
Seal packing: Part No.08826-00090, THREE BOND 1281 or equivalent
HINT: Install the carrier cover within 10 minutes after applying seal packing.
c. Install and torque the 11 bolts.
Torque: 39 Nm (400 kgf.cm, 29 ft. lbs.)
HINT: Each bolt length is indicated below.
Bolt length:
Bolt A: 100 mm (3.937 inch)
Bolt B: 65 mm (2.559 inch)
Bolt C: 75 mm (2.953 inch)
10. ADJUST SIDE BEARING PRELOAD
a. Remove any packing material on the contacting surfaces of the left-hand bearing retainer and transaxle case.
HINT: Do not apply seal packing yet.
b. Install the left-hand bearing retainer and torque the 6 bolts.
Torque: 19 Nm (195 kgf.cm, 14 ft. lbs.)
c. Snap down the bearings by turning the differential case several times.
d. Using a small torque wrench, measure the differential total preload.
Total preload (at starting):
New bearing: Drive pinion preload plus 0.2 - 0.4 Nm (2.5 - 5.1 kgf.cm, 2.2 - 3.6 inch lbs.)
Reused bearing: Drive pinion preload plus 0.1 - 0.2 Nm (1.3 - 2.0 kgf.cm, 1.1 - 1.7 inch lbs.)
If the preload is not within specification, replace the adjusting shim in the left-hand bearing retainer with one of a different thickness.
