vidually. Refer to EM-101, "
CONNECTING ROD BIG END DIAMETER" and EM-105, "CRANKSHAFT
PIN JOURNAL DIAMETER" .
2. Apply the measured dimension to the “Connecting Rod Bearing Selection 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 stan-
dard.

HOW TO SELECT MAIN BEARING
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 corrected 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”.
CAUTION:
There are two main bearing selection tables. One is for odd-numbered journals (No. 1, 3 and 5) and
the other is for even-numbered journals (No. 2 and 4). 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 EM-103, "
MAIN BEARING HOUSING INNER DIAMETER" and
EM-104, "
CRANKSHAFT MAIN JOURNAL DIAMETER" .
2. Apply the measured dimension to the “Main Bearing Selection Table”.

Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with
dial indicator.

If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crank-
shaft also.
CONNECTING ROD SIDE CLEARANCE

Measure the side clearance between connecting rod and crank-
shaft arm with feeler gauge.

If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crank-
shaft also.

Measure the inner diameter of piston pin hole with inside microme-
ter.
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)

When replacing piston and piston pin assembly, refer to EM-92, "HOW TO SELECT PISTON" .
NOTE:

Piston is available together with piston pin as an assembly.

The piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service
parts, no grades can be selected. (Only grade “0” is available.)
PISTON RING SIDE CLEARANCE

Measure the side clearance of piston ring and piston ring groove
with feeler gauge.

If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that cylinder bore inner diameter is within specifica-
tion. Refer to EM-103, "
Cylinder Bore Inner Diameter" .

Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure piston ring end gap with feeler gauge.

If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder inner wall and use oversized piston and piston rings.Standard:
