P O Undersize Bearings Usage Guide
 When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.
 When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the
fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).
