ENG
NOTE:
g. Remove the lower crankcase and the crank-
shaft journal lower bearings.
h. Measure the compressed Plastigauge
width
c
on each crankshaft journal.
If the crankshaft-journal-to-crankshaft-jour-
nal-bearing clearance is out of specification,
select replacement crankshaft journal bear-
ings.
2. Select:
Scrankshaft journal bearings (J1 X J5)
SThe numbers
A
stamped into the crankshaft
web and the numbers
1
stamped into the low-
er crankcase are used to determine the re-
placement crankshaft journal bearing sizes.
S“J1 X J5” refer to the bearings shown in the
crankshaft illustration.
SIf “J1 X J5” are the same, use the same size
for all of the bearings.
SIf the size is the same for all “J
1
to J
5
” one digit
for that size is indicated. (Crankcase side only)
For example, if the crankcase “J
1
” and crank-
shaft web “J
1
” numbers are “6” and “2” respec-
tively, then the bearing size for “J1” is:
“J
1
” (crankcase) – “J
1
”
(crankshaft web) – 1 =
6 – 2 – 1 = 3 (brown)
