HOW TO SELECT PISTON AND BEARING

UNDERSIZE BEARING USAGE GUIDE

• 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.

CAUTION:

In grinding crankshaft main journal to use undersize bearings,
keep the fillet R (A) [1.5 - 1.7 mm (0.059 - 0.067 in)].
