PINION SHAFT BEARING
General
See Figure 3-137. The right side pinion shaft bearing consists
of an inner and outer race with rollers.
The inner race (11) is pressed onto the pinion shaft. The
outer race is a pressed into the right crankcase half (14).
NOTE
If either inner or outer race show wear, measure both races to
confirm correct bearing fit.
NOTE
Pinion shaft bearing selection at the factory, during engine
build, or replacement of crankcase set or flywheel assembly
is based on the largest measured outside diameter (OD) of
the inner race and the smallest measured inside diameter
(ID) of the outer race (crankcase bushing). A running clear-
ance of 0.0002-0.0008 in. (0.0051-0.0203 mm) is established
during crankcase set or flywheel assembly replacement and
engine rebuild.
