bearings “1” and the balancer shaft into
the upper crankcase.
TIP
Align the projections “a” on the balancer shaft
journal upper bearings with the notches “b” in the
upper crankcase.

balancer shaft journal.
TIP
Do not put the Plastigauge® over the oil hole in
the balancer shaft journal.
e. Install the balancer shaft journal lower
bearings “1” into the lower crankcase and
assemble the crankcase halves.
