TRANSAXLE ASSEMBLY

• When adjusting striking rod end play, select adjusting shim (1) for

striking rod (2). To select adjusting shim, measure clearance

between transaxle case (3) and striking rod shim (4).

CAUTION:

Only 1 adjusting shim can be selected.

• Calculate dimension “R” (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of end play for striking

rod.

1. Using a depth micrometer (A) and straightedge (B), measure

dimension “R

1

” between transaxle case (1) end face and mount-

ing face of adjusting shim.

CAUTION:

“R

1

”: Measure at 4 point by approximately 90 degrees and

use the average value.

2. Using a depth micrometer (A) and straightedge (B) as shown,

measure dimension “R

2

” between clutch housing (1) end face

and end face of striking rod shim (2).

CAUTION:

• “R

2

”: Measure at 4 point by approximately 90 degrees and

use the average value.

• When measuring, be careful for the inclination of striking

rod assembly and striking rod shim.

3. Install selected striking rod adjusting shim onto striking rod

assembly.

MAINSHAFT END PLAY

• When adjusting mainshaft end play, select adjusting shim (1) for

mainshaft rear bearing (2). To select adjusting shim, measure

clearance “M” between transaxle case (3) and dummy adjusting

shim (4) on mainshaft rear bearing.

CAUTION:

Only 1 adjusting shim can be selected.

• Calculate dimension “P” (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of end play for mainshaft

rear bearing.

*: Refer to the latest parts information to use a dummy adjusting shim of which part number is the thinnest in thickness.

1. Install transaxle case according to the following:
a. Temporarily install snap ring of mainshaft rear bearing into tran-

saxle case.

CAUTION:

Do not reuse snap ring.

b. Install dummy adjusting shim (1) to mainshaft assembly.

c. With shifter lever A (1) held in the position shown, temporarily

assemble transaxle case to clutch housing.

CAUTION:

Do not damage striking rod oil seal.

NOTE:

Make sure to hold shifter lever A in the position shown. Other-

wise transaxle case cannot be installed to clutch housing.

d. While rotating shifter lever A (1) in the direction of the arrow

shown, assemble transaxle case to clutch housing.

TRANSAXLE ASSEMBLY

e. Accessing from the bore plug hole, expand snap ring at main-

shaft rear bearing so that the ring catches the periphery of main-

shaft rear bearing.

f.

Temporarily tighten transaxle case bolts.

2. Shift the shifter lever A to 2nd gear position.

NOTE:

• The 2nd gear position is attained when shifter lever A (1) is in

the position shown.

• 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.

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

assembly (1) is declined.

5. Set the dial indicator (A) to dummy adjusting shim (1) through

the bore plug mounting hole.

a. Shift the shifter lever A (1) to 2nd gear position (A), and then

rotate it in the direction of the arrow (C) until it stops. Using this

position as the reference point, measure the amount of move-

ment when shifting shifter lever A to 1st gear position (B) and

rotating it in the direction of the arrow (D) until it stops. This mea-

surement is the "M" dimension.

b. 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).
