Use Undersize Bearing Usage Guide
• When the specified main bearing oil clearance is not obtained with standard size main bearings, use under-
size (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.
CAUTION:
In grinding crankshaft main journal to use undersize bearings,
keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).
