CRANKSHAFT

e. Install the crankshaft journal lower bearings
“1” into the lower crankcase and assemble
the crankcase halves.
NOTE:
• Align the projections “a” of the crankshaft jour-
nal lower bearings with the notches “b” 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 5-55.
g. Remove the lower crankcase and the crank-
shaft journal lower bearings.
h. Measure the compressed Plastigauge
®
width
“a” on each crankshaft journal.
If the crankshaft-journal-to-crankshaft-jour-
nal-bearing clearance is out of specification,
select replacement crankshaft journal bear-
ings.

4. Select:
• Crankshaft journal bearings (J
1
–J
5
)
NOTE:
• The numbers “A” stamped into the crankshaft
web and the numbers “B” stamped into the
lower crankcase are used to determine the re-
placement crankshaft journal bearing sizes.
• J
1
–J
5
refer to the bearings shown in the crank-
shaft illustration.
• If J
1
–J
5
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 6 and 2 respective-
ly, then the bearing size for J
1
is:
J
1
(crankcase) - J
1
(crankshaft web)
=
6 - 2 = 4 (green)
