and disassemble
them.
NOTE:
Be sure to perform the steps 3) and 4)
after pulling the governor valve out
from the final reduction case.
2) Checking
Check the governor valve and body
visually and by feeling with a finger
for burrs and dents, and repair as
necessary.
If
the sliding surface of the
body or valve is defective, replace the
governor body
ASSY
with a new one.
3) Correcting
1) To correct the governor valve and
governor valve 2, lightly apply a fme
grained oil stone to the burred edge
as shown in the figure, and rotate the
valve one or two turns. Check whether
or not the burrs have been removed by
feeling with a finger.
Repeat this operation until the burrs
are no longer felt.
NOTE:
a. Note that the finishing of the end
face is not chamferring, but it is
light deburring. A sharp edge having
no burrs is desirable.
b. Replace the valve ASSY if flaws
and dents are noted on the sliding
surface.
2) Burrs and nicks at the edge of the
valve body groove should be removed
by using a small standard screwdriver.
3) Clean the repaired parts in clean
lamp oil or white gasoline. Fit the
governor valve and governor valve 2
into the valve body, and check for
smooth sliding of these parts by lightly
pressing them to the inside of the valve
body while rotating.
Check these areas.

NOTE:
9 - 11 N·m
(0.9 - 1.1
kg-m,

When tightening, fix the flange of the
shaft, and be careful not to damage
the nylon gear of the shaft.
3)
When assembling the governor
valve to the final reduction case, it is
unnecessary to dry out the governor
valve. However, the governor valve
should be assembled after confirming
that the seal ring is normal.
NOTE:
When assembling, use special care not
to damage the seal ring, and the lip
of the oil seal installed inside the case.
4) Before assembling the governor
cover, replace the gasket (governor
cover) and confirm that the washer is
included.

10) Adjusting the Brake Band
If the following abnormal shifting
conditions are noted in a road test, the
brake band must be adjusted.
1) Shift state and adjustment
1) The 2nd gear state can be achieved
but:
• the engine rpm increase excessively
shifting up from 2 to 3.
• a shift delay (over O. 7 sec) accom-
panies at kickdown from 3 to 2.
If any of these problems occurs, it is
attributable to excessive clearance
between the reverse clutch drum and
brake band: Tighten the adjust screw
by turning it clockwise.
2) The 2nd gear state can be
achieved, but:
• the shifting shock is too small at
shifting up from 1 to 2.
• a braking phenomenon is noted
when shifting up from 2 to 3.
