TRANSAXLE ASSEMBLY

2.

Shift the shifter lever A (1) to 2nd gear position.
NOTE:
• The 2nd gear position is attained when shifter lever A is in the

position shown in the figure.

• When transaxle is shifted to the 2nd gear position, mainshaft

assembly (1) is lifted.

3.

Seat snap ring in the groove on mainshaft rear bearing. If snap ring is not seated in the groove on main-
shaft rear bearing, remove transaxle case and repeat the procedure 1 from step c.

4.

Shift the shifter lever A to 1st gear position, and then shift it to 2nd gear position. Repeat 3 times.
NOTE:
• The mainshaft rear bearing position will be stabilized by shifting between 1st gear position and 2nd gear

position alternately.

• The 1st gear position is attained when shifter lever A (1) is in

the position shown in the figure.

• When transaxle is shifted to the 1st gear position, mainshaft

assembly (1) is declined.

Set the dial indicator (A) to dummy adjusting shim (1) through
the bore plug mounting hole.

6.

Shift the shifter lever A (1) to 2nd gear position (A), and then
rotate it in the direction of the arrow (C) in the figure until it stops.
Using this position as the reference point, measure the amount
of movement when shifting shifter lever A to 1st gear position (B)
and rotating it in the direction of the arrow (D) in the figure until it
stops. This measurement is the "M" dimension.

7.

When measurement "M" is 0 - 0.06 mm (0 - 0.0024 in), adjust-
ment terminates, and the dummy adjusting shim becomes regu-
lar adjusting shim. Select adjusting shim from the computed
expressions when measurement "M" is over 0.06 mm (0.0024
in).
