• When the specified main bearing oil clearance is not obtained with standard size main bearings, use under-
side (US) bearing.
• When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
