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.
Refer to MT-107, "

SHIM" .
CAUTION:
Only 1 adjusting shim can be selected.

Calculate dimension “P” (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for main-
shaft rear bearing.
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 indicator to bore plug mounting hole, and expand
snap ring. Lift mainshaft assembly through control assembly
installation hole, and push it against transaxle case. This state
shall be defined as base. Moving distance of mainshaft assem-
bly, with snap ring fit on main rear bearing, becomes “M”.End play: 0 - 0.06 mm (0 - 0.0024 in)
Dimension“P” = “M” - End play

Synchronizer
Check items below. If necessary, replace them with new ones.

Damage and excessive wear of contact surfaces of coupling
sleeve, synchronizer hub and shifting insert

Coupling sleeve and synchronizer hub must move smoothly.

If any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
BAULK RING CLEARANCE

Single-cone synchronizer (4th and 5th)
Push baulk ring on the cone, and measure the clearance
between baulk ring and cone. If measurement is below limit,
replace it with a new one.

Double-cone synchronizer (3rd)
Check the clearance between outer baulk ring, synchronizer
cone and inner baulk ring as follows.
CAUTION:
The clearances “A” and “B” are controlled with outer baulk
ring, synchronizer cone and inner baulk ring as a set.
Replace them as a set if the clearances are outside the limit
value.
