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:

Piston Skirt Diameter
Measure the outer diameter of piston skirt with micrometer.
Piston to Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”).
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter)

If it exceeds the limit, replace piston and piston pin assembly. Refer to EM-92, "HOW TO SELECT PIS-
TON" .
Re-boring Cylinder Bore
1. Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.
2. Install lower cylinder block, and tighten mounting bolts to the specified torque. Otherwise, cylinder bores
may be distorted in final assembly. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
3. Cut cylinder bores.
NOTE:

When any cylinder needs boring, all other cylinders must also be bored.

Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain specified piston to cylinder bore clearance.
5. Measure the finished cylinder bore for out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft main journals with
micrometer.

If out of the standard, measure the main bearing oil clearance.

CRANKSHAFT PIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft pin journal with micrometer.

If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
Refer to EM-105, "
CONNECTING ROD BEARING OIL CLEARANCE" .
OUT-OF-ROUND AND TAPER OF CRANKSHAFT

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.

Out-of-round is indicated by the difference in dimensions
between “X” and “Y” at “A” and “B”.

Taper is indicated by the difference in dimension between “A”
and “B” at “X” and “Y”.

If the measured valve exceeds the limit, correct or replace crankshaft.

If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select main bearing and/or connecting rod bearing. Refer to EM-106, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-105, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.

While rotating crankshaft, read the movement of the pointer on
the dial indicator. (Total indicator reading)

If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation

Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the speci-
fied torque. Refer to EM-86, "
