4. Check:
• transmission gear engagement
(each pinion gear to its respective
wheel gear)
Incorrect ® Reassemble the transmis-
sion axle assemblies.
5. Check:
• transmission gear movement
Rough movement ® Replace the
defective part(-s).
6. Check:
• circlips
Bends/damage/looseness ® Replace.
INSTALLING THE TRANSMISSION
1. Install:
• main axle assembly
• shift fork “C”
• shift drum assembly
• shift fork “R”
• shift fork “L”
• springs
• shift fork guide bars
• drive axle assembly
NOTE:
• Install the shift forks so that the
embossed marks “C”, “R”, and “L” are
facing toward the right side of the
engine.
• Carefully position the shift forks so
that they are installed correctly into the
transmission gears.
• Install shift fork “C” into the groove in
the 3rd and 4th pinion gear on the
main axle.
• Install shift fork “L” into the groove in
the 6th wheel gear and shift fork “R”
into the groove in the 5th wheel gear
on the drive axle.
• Make sure that the drive axle bearing
circlip is inserted into the grooves in
the upper crankcase.
2. Check:

Rough movement ® Repair.
NOTE:
Oil each gear, shaft, and bearing thor-
oughly.
