When replacing piston and piston pin assembly, refer to

EM-127, "HOW TO SELECT PISTON"

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.)

PISTON RING SIDE CLEARANCE

●

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

●

If the measured value 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 the cylinder bore inner diameter is within the
specification. Refer to

EM-136, "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.

Piston Skirt Diameter

Measure the outer diameter of piston skirt with a micrometer.

Piston to Cylinder Bore Clearance

Calculate by piston skirt diameter and cylinder bore inner diameter (direction “Y”, position “B”).

●

If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to

EM-127, "HOW

Re-boring Cylinder Bore

Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.

Install main bearing caps and main bearing beam, and tighten to the specified torque. Otherwise, cylinder
bores may be distorted in final assembly.

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.

Hone cylinders to obtain the specified piston to cylinder bore clearance.

Measure finished cylinder bore for the out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
