MANUAL TRANSMISSION AND DIFFERENTIAL
NOTE:
• Set the indicator of height gauge near measuring
object, then lock the dial (1) as shown in the figure.
Turn dial (2) to set the indicator to edge surface of
sleeve 2nd side.
• Perform the measuring procedure with two peo-
ple, and measure the sleeve lifted up straight.
• Measure five points of the sleeve turning every
approx. 72° apart. Round off each two upper and
lower measurement value. Use the remaining cen-
ter value as measurement value.
7) According to both measurements, calculate the
1st-2nd sleeve neutral position. Select the fork rod
which applies to the calculated value from following
equation.
Equation: T = (B1 + B2) / 2
T: 1st-2nd sleeve center position
B1: Height from adapter plate edge to sleeve
edge when shifted to 1st gear.
B2: Height from adapter plate edge to sleeve
edge when shifted to 2nd gear. [measure-
ment value + 55 mm (2.17 in)]
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
"B2", to obtain measurement value of "B2".

2. SELECTION OF 3rd-4th FORK ROD
NOTE:
Perform the following procedures when:
• Replacing the main shaft.
• Replacing the 3rd, 3rd to 6th drive gear and
bush.
• Replacing the 3rd, 3rd to 6th synchro assembly.
• Replacing the 3rd-4th 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, on 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.
• Do not put the height gauge on shaded area in
the figure during the measurement.
