Transaxle Assembly (Fig. 9)
1. During assembly of transaxle, lightly oil components
before installation into transaxle.
2. Use a press and appropriate installation tool to press
all removed bearings into transaxle cover and case
(Figs. 18 and 19).
IMPORTANT: When installing needle bearings,
press only on stamped side of bearing.
A. If installing needle bearings for low gear shaft
(item 62), press bearings into housing .010” (.254
mm) below the thrust surface.

C. Remaining needle bearings should be pressed
into housing .015” to .020” (.381 to .508 mm) below
the thrust surface.
3. Slide spur gear (item 40) (flat side of gear toward
center of transaxle) and thrust washer (item 74) on input
shaft (item 39). Install input shaft into case. Use a press
or soft–faced hammer to fully seat the shaft into the
case. If input shaft is not fully seated, transaxle binding
will occur.
4. Center thrust washer (item 73) on the cover brake
shaft needle bearing. Slide idler gear (item 35) onto
brake shaft (item 23) with the chamfer side of the gear
away from the cover. Install brake shaft assembly into
cover (Fig. 20).

5. Center thrust washer (item 41) on the output shaft
bearing. Slide output gear (item 43) onto output pinion
(item 44). Install output shaft assembly into cover. Place
thrust washer (item 41) on output pinion.
6. Insert differential assembly into the cover making
sure to orientate the differential bolt heads toward the
center of the transaxle.
7. Install the two gear cluster (item 27) and spacer (item
37) onto brake shaft (Fig. 21).
8. Install thrust washer (item 61), low gear shaft and
pinion (item 62) and spur gear (item 67) into cover. Make
sure that the small gear meshes with the larger gear of
the two gear cluster.
9. Slide shifting gears onto pinion shaft. Position shifter
assembly to sifting gears and pinion shaft making sure
that shift forks engage gear slots.
