Bearing Required
Note:
•
It
is
normal for the bearings selected to
differ
from
one journal
to
another.
It is also normai 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.
Crankshaft End Float
Crankshaft end float
Standard 0.05 - 0.20 mm
Service limit 0.40
mm
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.
