d. Install the crankshaft journal lower bearings
“3” into the crankcase and assemble the
crankcase and cylinder.
TIP
• Align the projections “d” of the crankshaft jour-
nal lower bearings with the notches “e” in the
crankcase.
• Do not move the crankshaft until the clearance
measurement has been completed.
e. Tighten the bolts to specification in the tight-
ening sequence cast on the crankcase.
Refer to “CRANKCASE” on page 5-69.
