●When adjusting input shaft end play, select adjusting shim for
input shaft bearing. To select adjusting shim, measure clearance
between transaxle case and input shaft rear bearing.
●Calculate dimension "O" (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for input
shaft rear bearing.

adjusting shim.
2. Using depth micrometer and straight edge as shown in the fig-
ure, measure dimension "O
2 " between clutch housing case end
face and end face of input shaft rear bearing.
3. Install selected input shaft rear bearing adjusting shim onto input
shaft.End play: 0 - 0.06 mm (0 - 0.0024 in)

MAINSHAFT END PLAY
●When adjusting mainshaft end play, select adjusting shim for
mainshaft rear bearing. To select adjusting shim, measure clear-
ance “M” between transaxle case and mainshaft rear bearing.
●Calculate dimension "P" (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for main-
shaft rear bearing.
Adjusting Shim
CAUTION:
Only 1 adjusting shim can be selected.
1. Install mainshaft assembly to clutch housing.
2. Install snap ring to transaxle case.
3. Install transaxle case to clutch housing, and temporarily assemble them with fixing bolts. Install tempo-
rarily snap ring to mainshaft rear bearing.
4. Install dial gauge to snap ring access hole, and expand snap
ring. Lift mainshaft assembly through control assembly installa-
tion hole, and push it against transaxle case. This state shall be
defined as base. Moving distance of mainshaft assembly, with
snap ring fit on main bearing, becomes “M”.End play: 0 - 0.06 mm (0 - 0.0024 in)
