MIDDLE GEAR
2. Loosen:
• middle driven shaft bearing housing bolts
3. Remove:
• shim(s)
4. Tighten:
• middle driven shaft bearing housing bolts
CAUTION:
@
Do not overtighten the middle driven shaft
bearing housing bolts or you may obtain
too little middle gear backlash, and damage
the middle gears and collapsible collar. If
the bolts are overtightened, replace the col-
lapsible collar. Then, repeat all of the previ-
ous steps until the crankcase-to-middle-
driven-shaft-bearing-housing clearance is
within specification.
@
NOTE:
@
• Tighten the middle driven shaft bearing
housing bolts carefully, one thread turn at a
time only. Push in the middle driven shaft
bearing housing and then tighten the bolts to
specification.
• Clearance between the crankcase and the
middle driven shaft bearing housing should
be approximately 2 mm, when measured
with a thickness gauge 2.
