Undersize Bearings Usage Guide

• When the specified oil clearance is not obtained with standard size connecting rod bearings, use undersize

(US) bearings.

• When using undersize bearing, measure the bearing inside diameter with the bearing installed, and grind the

crankshaft pin so that the oil clearance satisfies the standard.

Unit: mm (in)

CAUTION:

In grinding the crankshaft pin to use undersize bearings, keep
the fillet R (All crankshaft pins).

HOW TO SELECT MAIN BEARING

When New Cylinder Block and Crankshaft are Used

1.

Apply the main bearing housing grade on the bottom face of the
cylinder block to the row in "Main Bearings Selection Table".

HOW TO SELECT PISTON AND BEARING

2.

Apply the journal diameter grade on the crankshaft front to the
column in "Main Bearings Selection Table".

3.

Read the symbol at the cross point of the selected row and column in the "Main Bearings Selection Table".

CAUTION:

• Initial clearance for No. 1, 5 journal and No. 2, 3, 4 journal is different. Use two different selection

lists for each part. 

• No. 1, 5 journal and No. 2, 3, 4 journal have the same signs but different measures. Do not con-

fuse them. 

4.

Apply the symbol to the "Main Bearings Grade Table" to select.
NOTE:
• Grade list applies to all journals.
• Service parts are available as a set of both upper and lower.

When Cylinder Block and Crankshaft are Reused

1.

Measure the inside diameter of the cylinder block main bearings housing and the outside diameter of the
crankshaft journal.

2.

Apply measurement in above step 1 to "Main Bearings Selection Table".

3.

The following steps are same as in “When New Cylinder Block and Crankshaft are Used”. Follow the
"HOW TO SELECT MAIN BEARING" procedure.

Use Undersize Bearing Usage Guide

• Use undersize (US) bearing when the oil clearance with standard size main bearing is not within specifica-

tion.

• When using undersize (US) bearing, measure the inside diameter of the bearing installed and grind the jour-

nal until the oil clearance falls within specification.

CAUTION:

Do not damage fillet R when grinding crankshaft journal in
order to use undersized bearing (All journals).
