Transaxle Assembly - Toro Workman GTX Service Manual

Transaxle Assembly (Fig. 19)
1. Clean sealant material from transaxle RH and LH
case mating surfaces before transaxle assembly. Make
sure all transaxle parts are clean.
2. Replace all removed bearings and seals during

transaxle assembly.

IMPORTANT: When pressing
transaxle shafts, make sure to press bearing only
on the inner race to prevent damaging the bearing.
3. Press new bearings onto the input shaft (Fig. 30).
Make sure bearings are pressed fully to the shaft shoul-
der.
4. Assemble the counter shaft (Fig. 31):
A. Press gear 34 onto shaft fully to the shoulder on
the counter shaft.
B. Press new bearings onto the counter shaft. Make
sure bearings are pressed fully to the shaft shoulder.
5. Assemble differential case (Fig. 32):
A. Apply a coating of oil to all surfaces of pinion and
side gears.
B. Place first side gear into case and then position
both pinion gears into case making sure that gear
teeth mesh properly with side gear.
C. Slide pinion shaft through case and installed pin-
ion gears.
D. Align holes in pinion shaft and differential case to
allow installation of pin. Install new pin into the differ-
ential case to secure pinion shaft.
E. Place second side gear into case making sure
that gear teeth mesh properly with pinion gears.
F. Install gear 60 to case with outer side gear fitted to
bore in gear 60. Gear 60 should fit flush with case
surface and side and pinion gears must rotate freely.
G. Secure gear 60 to case with six (6) bolts. Torque
bolts in a crossing pattern from 40 to 45 ft−lb (54 to
61 N−m).
H. Press new bearings onto the differential case as-
sembly. Make sure bearings are pressed fully to the
shoulders on gear 60 and the differential case.
