• The numbers “A” stamped into the lower crank-
case and the numbers “B” stamped into the
balancer shaft web are used to determine the
replacement balancer shaft journal bearing siz-
es.
• J

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

–J
4
are the same, use the same size for all
of the bearings.
For example, if the lower crankcase J
1
and
balancer shaft web J

numbers are 8 and 5
respectively, then the bearing size for J
1
is:
