g. Remove the lower crankcase and the crank-
shaft journal lower bearings.
h. Measure the compressed Plastigauge
width 1 on each crankshaft journal.
If the clearance is out of specification, select
replacement crankshaft journal bearings.
4. Select:
Crankshaft journal bearings (J1 X J5)
For example, if the crankcase “J1” and crank-
shaft web “J1” numbers are “6” and “2” respec-
tively, then the bearing size for “J1” is:
Bearing size for J1:
J1 (crankcase) – J1 (crankshaft web) =
6 – 2 = 4 (green)
