If the crankshaft-journal-to-crankshaft-jour-
nal-bearing clearance is out of specification,

S
crankshaft journal bearings (J1

S
The 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.
S
If “J1
X
J5” are the same, use the same size
for all of the bearings.
S
If 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)
