Using Undersize Bearing

• If the standard oil clearance cannot be obtained by standard size connecting rod bearing, use undersize

(US) bearing.

• When using undersize bearing, install it, measure bearing inner diameter, and then grind crankshaft pin to

obtain specified oil clearance.

SELECTIVE-FIT MAIN BEARING

Using New Cylinder Block and Crankshaft

1. Find the bearing housing grade of cylinder block LH side (L) in

the row of the Selective-fit Service Parts Table.

• If there is a correction stamp, the symbol is the correct one.

2. Find the journal diameter grade of crankshaft front surface in the

column of the Selective-fit Service Parts Table.

3. Find the symbol at the intersection of the selected row and column in the Selective-fit Service Parts Table.

CAUTION:

The setting clearance is different between journal No. 1 and 4, and No. 2, 3, and 5. Use either 2

selective-fit service parts depending on the position.

4. Find the symbol at the intersection in "MAIN BEARING GRADE TABLE" and select it.

NOTE:

Set the upper/lower values for service parts as a set.
