d. Measure the crankshaft journal bearing in-
side diameter “b” of each crankshaft journal
bearing at two places.
e. If crankshaft journal bearing inside diameter
is “45.03” and crankshaft journal diameter is
“44.98”, then the journal oil clearance is:
If the oil clearance is out of specification, se-
lect replacement bearings.

6. Select:
• Crankshaft journal bearings (J
1
–J
2
)
TIP
• The numbers “A” stamped into the crankshaft
web and the numbers “B” on the crankcase are
used to determine the replacement crankshaft
journal bearing size.
• J
1
–J
2
refer to the bearings shown in the crank-
shaft illustration.
For example, if the crankcase J
1
and the
crankshaft web J
1
numbers are 4 and 2 re-
spectively, then the bearing size for J
1
is:

INSTALLING THE CRANKSHAFT JOURNAL
BEARINGS
The following procedure applies to both of the
crankshaft main journal bearings.
1. Attach:
• Crankshaft journal bearing “1”
TIP
Attach the crankshaft journal bearing to the
plane bearing installer “2”.
2. Install:
• Crankshaft journal bearing
TIP
• Align the projection “a” on the bearing with the
projection “b” on the crankcase.
• Place an iron “3” plate beneath the crankcase
and press fit until the end of the plain bearing
installer touches the iron plate.
