NOTE: _
Tighten the bolts carefully, one thread turn
at a time, only. Push in the bearing housing
and tighten the bearing housing bolts.
Do not overtighten the bearing housing
bolts or you may obtain too little gear
backlash and cause damage to the gears. If
over tightened, loosen the three bolts so
that the crankcase/bearing housing clear-
ance is about 2 mm and repeat all previous
steps.

gear backlash is achieved.
