replacement is necessary.
SECONDARY OUTPUT DRIVE
GEARS
Initial Set-Up
NOTE: If the secondary output driven shaft is
replaced or disassembled, the initial set-up must
be performed to establish correct gear tooth con-
tact. If only the secondary output driveshaft or
secondary output driven gear are replaced, pro-
ceed to Correcting Backlash in this sub-section.
1. Install a new bearing (A) onto the secondary driven
shaft (B) making sure the bearing locating groove is
directed away from the driven gear splines.

2. Using a suitable press, install the driven gear (C)
on the shaft until the gear firmly seats on the
shoulder of the shaft.

3. If installing the existing shaft, start with the shims
removed during disassembly or if installing a new
shaft, start with approximately 1.0 mm shims at
point (D); then install the output driveshaft bearing
(E) making sure the locating pin is directed toward
the center of the shaft.

4. Install a new seal (F), output yoke (G), and nut (H)
and tighten to 74 ft-lb.

NOTE: Do not use a new lock nut at this time as
this procedure may have to be repeated.
5. Place the assembled shaft into the left crankshaft
case; then lightly coat the gear teeth with machin-
ist's lay-out dye. Rotate the shafts through several
rotations in both directions. Gear contact should
extend from the root to the top of the gear teeth.
