Under Size Bearing Usage
lIf bearing clearance is out of the specifications for main bearings in standard size, use under size bear-
ings.
lWhen using under size bearings, measure bearing inner diameter with bearing installed, and grind crank-
shaft journals to adjust clearance to the specification.

Unit: mm (in)
CAUTION:
When grinding crank journals to use under size bearings, keep
corners radius of fillet R. (All journals)

CRANKSHAFT END PLAY
lUsing dial gauge, measure crankshaft travel amount by moving
the crankshaft forward or backward.
lIf the value exceeds the limit, replace thrust bearings with new
ones and measure again.
If the measurement exceeds the limit again, replace crankshaft
with a new one.
