3. Select connecting rod bearing grade at the point where selected row and column meet in “Connecting
Rod Bearing Selection Table”.
When Crankshaft and Connecting Rod are Reused
1. Measure the connecting rod big end diameter and crankshaft pin journal diameter. Refer to EM-127,
"CONNECTING ROD BIG END DIAMETER" . and EM-131, "CRANKSHAFT PIN JOURNAL DIAMETER"
.
2. Correspond the measured dimension in “Connecting rod big end diameter” row of “Connecting Rod Bear-
ing Selection Table”.
3. Correspond the measured dimension in “Crankshaft pin journal diameter” column of “Connecting Rod
Bearing Selection Table”.
4. Select connecting rod bearing grade at the point where selected row and column meet in following selec-
tion table.

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 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)].

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft are Used
1. “Main Bearing Selection Table” rows correspond to bearing
housing grade on rear left side of cylinder block.
2. “Main Bearing Selection Table” columns correspond to journal
diameter grade on front side of crankshaft.
