Transaxle Disassembly (Fig. 9)
1. Drain lubricant from transaxle and clean outside of
transaxle before disassembly.
2. Place the transaxle in neutral. Remove three (3)
socket head screws (item 1) that secure shift lever as-
sembly to transaxle. Lift shift lever assembly, gaskets
and shift guide plate from transaxle. See Shift Lever Ser -
vice in this section for shift lever assembly service.
3. For assembly purposes, mark axle housings and
transaxle to identify orientation of axle housings. Re-
move cap screws (item 51) and lock washers (item 53)
that secure axle housings to the transaxle. Pull axle
housings from the transaxle case and cover.
4. Use exposed axles as a ram to separate seal retain -
ers from transaxle case and cover. Remove and discard
seals (item 45) and o–rings (item 72) from retainers.
5. Support transaxle so it is resting on the cover with no
weight on the brake shaft. Make sure that transaxle is
well supported to prevent it from shifting or falling during
disassembly procedure.
6. Tap two (2) dowel pins (item 50) into the cover and
then remove eleven (11) flange head screws (item 49).
7. Lift the case 1 1/2 to 2 inches (38 to 50.8 mm) and tilt
case so that the shifter rods will clear the edge of the
case. Rotate case so the boss hidden inside will clear
the gears. Lift case from transaxle (Fig. 10).
NOTE: Refer to Figure 11 for transaxle gear and shaft
identification during disassembly.
8. Remove thrust washer (item 16) and three gear clus-
ter (item 36) from the brake shaft.
