HOW TO SELECT PISTON AND BEARING
1.
Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to
2.
Apply the measured dimension to the “Connecting Rod Bearing Selection Table”.
3.
Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection
Table”.
4.
Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.

CONNECTING ROD BEARING GRADE 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 the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.

WHEN NEW CYLINDER BLOCK AND CRANKSHAFT ARE USED
1.
“Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear left side of cylinder block
.
• If there is a correction stamp mark on cylinder block, use it as
a correct reference.
2.
Apply main journal diameter grade stamped on crankshaft front
side to column in the “Main Bearing Selection Table”.
3.
Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.

HOW TO SELECT PISTON AND BEARING
There are two main bearing selection tables. One is for No. 1 and 4 journals and the other is for
No. 2, 3 and 5 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.
4.
Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing.
NOTE:
Service part is available as a set of both upper and lower.
WHEN CYLINDER BLOCK AND CRANKSHAFT ARE REUSED
1.
Measure the dimensions of the cylinder block main bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to
2.
Apply the measured dimension to the “Main Bearing Selection Table”.
3.
Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
CAUTION:
There are two main bearing selection tables. One is for No. 1 and 4 journals and the other is for No.
2, 3 and 5 journals. Make certain to use the appropriate table. This is due to differences in the
specified clearances.
