Use Undersize Bearing Usage Guide

• Use undersize (US) bearing when the oil clearance with standard size main bearing is not within specifica-

tion.

• When using undersize (US) bearing, measure the inside diameter of the bearing installed and grind the jour-

nal until the oil clearance falls within specification.

CAUTION:

Do not damage fillet R when grinding crankshaft journal in

order to use undersized bearing (All journals).
