CRANKSHAFT
5-92
e. Install the crankshaft journal lower bearings
“3” into the lower crankcase and assemble
the crankcase halves.
NOTE:
• Align the projections “c” of the crankshaft jour-
nal lower bearings with the notches “d” in the
lower crankcase.
• Do not move the crankshaft until the clearance
measurement has been completed.
f. Tighten the bolts to specification in the tight-
ening sequence cast on the crankcase.
Refer to “CRANKCASE” on page 5-74.
g. Remove the lower crankcase and the crank-
shaft journal lower bearings.
h. Measure the compressed Plastigauge
®
width
“e” on each crankshaft journal.
If the crankshaft-journal-to-crankshaft-jour-
nal-bearing clearance is out of specification,
select replacement crankshaft journal bear-
ings.

–J

)
NOTE:
• The numbers “A” stamped into the lower crank-
case and the numbers “B” stamped into the
crankshaft web are used to determine the re-
placement crankshaft journal bearing sizes.
• J

refer to the bearings shown in the lower
crankcase and crankshaft web illustration.
• If J

–J
5
are the same, use the same size for all
of the bearings.
For example, if the lower crankcase J
1
and
crankshaft web J
1
numbers are 6 and 2 re-
spectively, then the bearing size for J
1
is:
