"1" into the lower crankcase and assem-
ble the crankcase halves.
TIP
---------------
• Align the projections "a" of the balancer shaft
journal lower bearings with the notches "b" in
the crankcase.
•
Do
not move the balancer shaft until the clear-
ance measurement has been completed.
f. Tighten the bolts to specification
in
the tight-
ening sequence cast on the crankcase. Refer
to "CRANKCASE" on page
5-56.
g. Remove the lower crankcase and the
ba
lanc-
er shaft journal lower bearings.
h. Measure t
he
compressed Plastigauge®
width "a" on each balancer shaft journal. If the
balancer shaft-
