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.
