8) According to both of the measurements, calcu-
late the neutral position of the 1st-2nd sleeve. From
the following calculation, select a fork rod which
matches the calculated value.
Calculation: T = (B1 + B2) / 2
T: 1st-2nd sleeve center position
B1: Height from the adapter plate end to the sleeve
end, when shifted to 1st gear
B2: Measured height from the adapter plate end to
the sleeve end, when shifted to 2nd gear: +55 mm
(2.17 in)

NOTE:
Attach the indicator upside down in comparison to
the setting procedures for the 0 point. Add “d1”
[Value: 55 mm (2.17 in)] from the figure below to
“B2”, and measure “B2”.

2. 3RD-4TH FORK ROD SELECTION

NOTE:
In the following conditions, perform the procedures
below.
• Replacing the main shaft
• Replacing the 3rd, and 3rd to 6th drive gear and
bushing
• Replacing the 3rd, and 3rd to 6th synchro as-
semblies
• Replacing the 3rd-4th hub and sleeve assem-
blies
1) Insert the main shaft assembly into the adapter
plate.
2) Set the height gauge to the adapter plate. Lower
the height gauge indicator to the top surface of the
snap ring groove, and set to the zero point on the
upper side of the main rear bearing.

HEIGHT GAUGE

NOTE:
• The height gauge will be set on the adapter plate
during the measurement. Use a scraper to remove
any gasket material remaining on the end face.
• During measurement, do not place the height
gauge in the shaded area shown in the figure.

3) Use a height gauge to measure “C1” and “C2” as
shown in the figure.

(1) Shift the 3rd-4th sleeve to the 4th gear side,
push up on the stopper, and measure “C2”.

NOTE:
• Set the height gauge indicator near the measure-
ment target, and lock dial (1) as shown in the figure.
• Turn dial (2), and set the indicator to the 4th side
end surface of the sleeve.
• The measurement is to be performed with 2 per-
sons, while holding the sleeve straight.
• Turn approximately 72° at a time, and measure
the sleeve in 5 locations. Round down the 2 highest
and 2 lowest measurement values. The remaining
center value is used as the measurement value.

(2) Set the height gauge indicator upside down.

side, push down to the stopper, and measure
“C1”.

NOTE:

Turn dial (2), and set the indicator to the 3rd side
end surface of the sleeve.
• Turn approximately 72° at a time, and measure

4) According to both of the measurements, calcu-
late the neutral position of the 3rd-4th sleeve. From
the following calculation, select a fork rod which
matches the calculated value.
Calculation: T = (C1 + C2) / 2
T: 3rd-4th sleeve center position
C1: Measured depth from the main shaft rear bear-
ing snap ring groove to the sleeve end, when shift-
ed to 3rd gear: +55 mm (2.17 in)
C2: Measured depth from the main shaft rear bear-
ing snap ring groove to the sleeve end, when shift-
ed to 4th gear

NOTE:
Attach the indicator upside down in comparison to
the setting procedures for the 0 point. Add “d1”
[Value: 55 mm (2.17 in)] from the figure below to
“C1”, and measure “C1”.
