MANUAL TRANSMISSION AND DIFFERENTIAL
• Measure five points of the sleeve turning every
approx. 72°. Round off each two upper and lower
measurement value. Use the remaining center val-
ue as measurement value.
4) According to both measurements, calculate the
3rd-4th sleeve neutral position. Select the fork rod
which applies to the calculated value from following
equation.
Equation: T = (C1 + C2) / 2
T: 3rd-4th sleeve center position
C1: Length from main shaft rear bearing snap
ring groove to sleeve edge when shifted to
3rd gear. [measurement value +55 mm (2.17
in)]
C2: Length from main shaft rear bearing snap
ring groove to sleeve edge when shifted to
4th gear.
NOTE:
The indicator is installed upside down compared to
the setting procedure of zero point. Add d1 [fixing
value: 55 mm (2.17 in)] from the following figure to
"C1", to obtain measurement value of "C1".

3. SELECTION OF 5th-6th FORK ROD
NOTE:
Perform the following procedures when:
• Replacing the main shaft.
• Replacing the 3rd to 6th drive gear and bush.
• Replacing the 3rd to 6th synchro ring assembly.
• Replacing the 3rd-4th hub, sleeve assembly.
• Replacing the 5th-6th hub, sleeve assembly.
1) Insert the main shaft assembly in adapter plate.
2) Set the height gauge to adapter plate. Lower the
indicator of height gauge to upper surface of snap
ring groove, or the upper side of main rear bearing.
Then set to zero point.

NOTE:
• Remove the remaining gasket on edge surface
with scraper, since the height gauge is set on
adapter plate during measurement.
