8) Inspect the support bearings for excessive wear.
Replace as necessary. Install the replacement drum
and shaft assembly in the transmission cover.
Determine the drum fits tight against the bearings.
9) Apply a suitable amount of tread anti-seize material
to the exterior threads of the drum shaft. Reinstall the
pinion gear, PN 210-0320 to the drum shaft. Thread by
hand. If additional torque is required, the pinion gear
can be assembled to the shaft utilizing the impact
wrench and the 12 point, 25/32 inch socket. Thread the
pinion gear on the shaft until it fits tight against the
bearing. A thrust force that places an excessive preload
against the bearing is not necessary and can actually
reduce bearing service life.
10) Reinstall the primary gear and pinion assembly.
Determine there is sufficient grease equally spread
around all gear teeth. Replace the old transmission
gasket with a new gasket, PN 240-0100. Align the
transmission dowel pins when reinstalling the cover.
Reinstall the fasteners with the hexagon huts on the
cover side of the transmission. Torque all fasteners to
96 inch lbs (12 N.m.) in an "X" sequence.
11) If necessary, reinstall PN 37040200 Screw into the
bearing housings. Properly secure with the provided
hardware.
12) Rotate the final driveshaft and check for excessive
noise and/or binding. If excessive noise and/or binding
is evident, disassemble the transmission and
investigate for probable causes. Reassemble and
retorque to the specified value. Recheck for excessive
noise and/or binding.
13) Inspect the centrifugal clutch assembly for
excessive wear and/or damage. If it is determined the
centrifugal clutch rotor and shoe assembly requires
replacement, refer to
ROTOR AND SHOE ASSEMBLY REMOVAL AND
INSTALLATION in the Service section of this manual
for additional information.
14) Reinstall the engine and operator handle to the
transmission. Torque the fasteners to 90 inch lbs (10
N.m.) in an "X" sequence.
15) Refill the engine crankcase with the correct amount
and type of grease. Refer to FILLING THE ENGINE
CRANKCASE WITH OIL in the Before Starting the
Engine section of this manual for additional
information.
16) Determine that the disassembly process has not
affected the proper operation of the twist grip throttle
control. If improper operation is detected, determine
the probable cause(s). Replace
component with a factory approved replacement part
only.
