Tighten transmission assembly mounting bolts to the specified
torque. The figure is the view from the vehicle forward.
Install clutch tube (1), clutch hose (2), and lock plate (3) and
then tighten clutch tube flare nut to the specified torque. Refer to
CL-15, "
Removal and Installation" .
CAUTION:
The transmission assembly must not interfere with the wire
harnesses and clutch hose.
When installing, be careful to avoid interference between transmission main drive gear and clutch
cover.
If flywheel is removed, align dowel pin with the smallest hole of flywheel. Refer to EM-111,
"ASSEMBLY" .
Do not impact or damage propeller shaft tube.
Refer to MT-14, "INSTALLATION" and MT-16, "INSPECTION AFTER INSTALLATION" for control
lever installation information.
After installation, check oil level, and oil leaks and loose mechanisms. Refer to MT-9, "Checking M/
T Oil" .
Do not hold control lever housing to prevent bushing of control lever housing from deformation
when moving transmission assembly.
