CRANKSHAFT AND BALANCER SHAFT

d. Install the crankshaft journal lower bear-
ings “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
tightening sequence cast on the crank-
case.
Refer to “CRANKCASE” on page 5-60.
f. Remove the crankcase and the crankshaft
journal lower bearings.
g. Measure the compressed Plastigauge®
width “g” on each crankshaft journal.
If the crankshaft-journal-to-crankshaft-
journal-bearing clearance is out of specifi-
cation, select replacement crankshaft
journal bearings.
5. Select:
• Crankshaft journal bearings (J
1
–J
3
)
TIP
• The numbers “A” stamped into the crankcase
and the numbers “B” stamped into the crank-
shaft web are used to determine the replace-
ment crankshaft journal bearing sizes.
• J
1
–J
3
refer to the bearings shown in the crank-
case and crankshaft web illustration.
• If J
1
–J
3
are the same, use the same size for all
of the bearings.
For example, if the crankcase J
1
and crank-
shaft web J
1
numbers are 5 and 3 respective-
ly, then the bearing size for J
1
is:
2
e
d
3
g
J

(crankshaft web) –2
= 5 – 3 – 2
