Crankshaft
Select bearings as follows:
1.
Measure and record the diameter of each crankshaft
main bearing journal.
2.
Measure and record each main bearing bore
diameter in the crankcase (bearings removed but all
crankcase bolts fully torqued) (see page 5-9).

It is normal for the bearings selected to differ
from one journal to another.
It is also normal for there to be two options of bearing
shell colour. In such cases, pick the shell size that gives the
greater running clearance.
Always confirm, using the Plastigage method, that the
running clearance is correct before final assembly.
Severe engine damage could result from incorrect
clearance resulting in loss of motorcycle control and an
accident.
Note:
•
The original crankcase bolts may be reused for
bearing selection. Do not use new bolts as they
may only be used once, even if the single use is
related to bearing selection.

Note:
•
Crankshaft end float is controlled by the
tolerances
in
crankshaft
and
crankcase
machining. Thrust washers are not used. If
crankshaft end float is outside the specified
limit, the crankshaft and/or the crankcases
must be replaced.
