5) Using gaging plastic, check bearing clearance with newly se-
lected standard bearing.
If clearance still exceeds its limit, use next thicker bearing and
recheck clearance.
If clearance can not be still brought to within its limit even by us-
ing a new standard size bearing, regrind crank pin to under size
and use 0.25 mm undersize bearing.
Crankshaft journal diameter (0.25 mm undersize):
57.732 – 57.750 mm (2.2729 – 2.2736 in.)
6) When replacing crankshaft or cylinder block and lower crank
case due to any reason, select new standard bearings to be
installed by referring to number stamped on new crankshaft or
