DIFFERENTIAL AND DRIVE PINION
INSTALLATION
1. INSTALL DRIVE PINION INTO TRANSAXLE CASE
(a) Using SST, install the bearing to the drive pinion shaft.
SST 09350±32014 (09351±32120)
(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.

5. INSTALL COUNTER DRIVE GEAR AND FRONT BEAR-
ING
(a) Install the gear onto the shaft, and mesh the ring gear with
the planetary pinions.
(b) Place the front bearing on to the shaft.
(c) Using SST, press in the bearing until there is slight play
between the bearings.
SST 09350±32014 (09351±32120)
HINT: Hold the ring gear to prevent it from falling.
6. INSTALL INTERMEDIATE SHAFT BEARING
Using SST, press in the bearing until it slightly touches the
front bearing of the counter drive gear.
SST 09350±32014 (09351±32120)
HINT: The counter drive gear can be turned lightly.
7. PLACE NEW LOCKING WASHER
8. INSTALL ADJUSTING NUT AND ADJUST PRELOAD
OF COUNTER DRIVE GEAR
(a) Hold the overdrive planetary gear in a vise with soft jaws.
(b) Using SST, tighten the adjusting nut until the following
gear starting load is reached on the tension gauge.
