Undersize Bearings Usage Guide

• When the specified oil clearance is not obtained with standard size connecting rod bearings, use undersize (US) bearings.
• When using undersize bearing, measure the bearing inside diameter with the bearing installed, and grind the crankshaft pin so that the oil clearance satisfies the standard.
