NOTE
The different sizes of crankcase sets and flywheel assemblies
will not have separate part numbers. That is, a replacement
crankcase set may have a class 1, 2 or 3 pinion bearing outer
race. Replacement flywheel assemblies will have either a class
A or B inner race which is identified by paint dots. Refer to
Table 3-26 .

NOTE
If either inner or outer race show wear, measure both races to
confirm correct bearing fit.
1. Use a dial bore gauge to measure and record ID of outer
race. Take four measurements on ID where bearing rollers
ride.
a. If the largest measurement is larger than 1.5656
in. (39.76 mm) or the required lapping to remove wear
marks would enlarge bore beyond 1.5656 in., continue
at Step 5.
b. If largest measurement is 1.5656 in. (39.76 mm) or
less, cover the cam bearings with masking tape to
prevent debris from entering bearings. Assemble
crankcase halves.
