If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing.
Refer to EM-132, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft pin and the surfaces
of each bearing completely.

Cut a plastigage slightly shorter than bearing width, and place it
in crankshaft axial direction, avoiding oil holes.

Install connecting rod bearings to connecting rod and connect-
ing rod bearing cap, and tighten connecting rod bolts to the
specified torque. Refer to EM-126, "
ASSEMBLY" for the tighten-
ing procedure.
CAUTION:
Never rotate crankshaft.

Remove connecting rod cap and bearings, and using the scale
on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is same as that described in the “Method by
Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and main bearing cap.
Measure the main bearing inner diameter with bearing cap bolt
tightened with main bearing beam to the specified torque. Refer
to EM-126, "
ASSEMBLY" for the tightening procedure.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)

If the measured value exceeds the limit, select main bearings
referring to the main bearing inner diameter and crankshaft jour-
nal outer diameter, so that the oil clearance satisfies the standard. Refer to EM-133, "
HOW TO SELECT
MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft journal and the sur-
faces of each bearing completely.

Cut a plastigage slightly shorter than bearing width, and place it
in crankshaft axial direction, avoiding oil holes.

Install main bearing to cylinder block and main bearing cap, and
tighten main bearing bolts with main bearing beam to the speci-
fied torque. Refer to EM-126, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Never rotate crankshaft.

Remove bearing cap and bearings, and using the scale on the
plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is same as that described in the “Method by
Calculation”.

DRIVE PLATE

Check drive plate and signal plate for deformation or damage.
CAUTION:

Do not disassemble drive plate.

Never place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate.
OIL JET

Check nozzle for deformation and damage.

Blow compressed air from nozzle, and check for clogs.

If it is not satisfied, clean or replace oil jet.
OIL JET RELIEF VALVE

Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.

If it is not satisfied, replace oil jet relief valve.

Piston Selection Table
Unit: mm (in)
NOTE:

Piston is available together with piston pin as assembly.

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

No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft Are Used:
Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and
select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
When Crankshaft and Connecting Rod Are Reused:
1. Measure the connecting rod big end diameter. Refer to EM-258, "CONNECTING ROD BIG END DIAME-
TER" .
2. Make sure that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-262, "
CRANKSHAFT PIN JOURNAL DIAME-
TER" .
4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in
“Crankshaft pin journal diameter” column of “Connecting Rod Bearing Selection Table”.
5. Select connecting rod bearing of the same grade.

Under Size 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 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.

ings, keep the fillet R [1.5 mm (0.059 in)].

Measure the distortion on the cylinder block upper face at some
different points in six directions with straightedge and feeler
gauge.

If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Install main bearing caps and main bearing beam without install-
ing main bearings, and tighten main bearing cap bolts to the
specified torque. Refer to EM-244, "
ASSEMBLY" for the tight-
ening procedure.

Measure the inner diameter of main bearing housing with bore
gauge.

If out of the standard, replace cylinder block and main bearing
caps as assembly.
NOTE:
Cylinder block cannot be replaced as single part, because it is
machined together with main bearing caps.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter

Using bore gauge, measure cylinder bore for wear, out-of-round
and taper at six different points on each cylinder. (“X” and “Y”
directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
engine)

If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or re-bore the
inner wall.

Oversize piston is provided. When using oversize piston, re-
bore cylinder so that the clearance of the piston-to-cylinder bore
satisfies the standard.
CAUTION:
When using oversize piston, use it for all cylinders with
oversize piston rings.Limit : 0.1 mm (0.004 in)
