8.
Select the proper piston related to the cylinder bore
class.
Clearance : 0.02 ~ 0.04mm(0.0008 ~ 0.0016in.)
CYLINDER BORING
1.
The over size piston is chosen on the maximum inner
diameter of the cylinder.
NOTE
The piston size mark is on the top surface of the pis-
ton.
2.
Measure the outer diameter of the piston which is in-
stalled before.
3.
Calculate the new bore size with the measurement in
the step 2.
New bore size = measured outer diameter of piston
+ 0.02 ~ 0.04mm(0.0008~0.0016in.)[clearance]
- 0.01mm(0.0004in.)[for horning]
4.
Bore the cylinder to the calculated size.
CAUTION
Bore the cylinders in firing order to prevent the
cylinders from be twisted by high temperature.
5.
Stop boring and start horning for the proper clear-
ance.
6.
Measure the clearance between a piston and a cylin-
der.
Specification
0.02 ~ 0.04mm(0.0008 ~ 0.0016in.)
NOTE
Bore all the cylinders with the same over size.

PISTON AND RINGS
1.
Clean pistons.
1)
Using a gasket scraper, remove the carbon from
the piston top.
2)
Using a groove cleaning tool or a broken ring,
clean the piston ring grooves.
3)
Using solvent and a brush, thoroughly clean the
piston.
NOTE
Do not use a wire brush.
2.
The standard measurement of the piston outside di-
ameter is taken 14 mm (0.5512 in.) from the bottom
of the piston.
Standard diameter
86.67 ~ 87.00(3.4122 ~ 3.4252in.)
ECKD001D
3.
Calculate the difference between the cylinder bore in-
ner diameter and the piston outer diameter.
Piston-to-cylinder clearance
0.02 ~ 0.04mm(0.0008 ~ 0.0016in.)
4.
Inspect the piston ring side clearance.
Using a feeler gauge, measure the clearance between
a new piston ring and the ring groove.
Piston ring side clearance
Standard
No.1 : 0.04 ~ 0.08mm (0.0016 ~ 0.0031in.)
No.2 : 0.03 ~ 0.07mm (0.0012 ~ 0.0027in.)
Oil ring : 0.06 ~ 0.15mm (0.0024 ~ 0.0059in.)
Limit
No.1 : 0.1mm (0.004in.)
No.2 : 0.1mm (0.004in.)
Oil ring : 0.2mm (0.008in.)
LDLG045A
If the clearance is greater than the maximum, replace
the piston.

5.
Inspect piston ring end gap.
To measure the piston ring end gap, insert a piston
ring into the cylinder bore. Position the ring at right
angles to the cylinder wall by gently pressing it down
with a piston. Measure the gap with a feeler gauge.
If the gap exceeds the service limit, replace the pis-
ton ring. If the gap is too large, recheck the cylinder
bore diameter. If the bore is over the service limit, the
cylinder block must be replaced or bored
Piston ring end gap
Standard
No.1 : 0.15 ~ 0.30mm (0.0059 ~ 0.0118in.)
No.2 : 0.30 ~ 0.45m (0.0118 ~ 0.0177in.)
Oil ring : 0.20 ~ 0.70mm (0.0079 ~ 0.0275in.)
Limit
No.1 : 0.6mm (0.0236in.)
No.2 : 0.7mm (0.0275in.)
Oil ring : 0.8mm (0.0315in.)

PISTON PINS
1.
Measure the outer diameter of the piston pin.
Piston pin outerdiameter
21.001 ~ 21.007mm (0.8268 ~ 0.8270in.)
ECKD001Z
2.
Measure the piston pin-to-piston clearance.
Piston pin-to-piston clearance
0.007 ~ 0.022mm (0.0003 ~ 0.0009in.)
3.
Check the difference between the piston pin outer di-
ameter and the connecting rod small end inner diam-
eter.
Piston pin-to-connecting rod interference
-0.033 ~ -0.016mm (-0.0013 ~ -0.0006in.)

REASSEMBLY
EBDEDDF4
NOTE
• Thoroughly clean all parts before reassembling.
• Before installing the parts, apply fresh engine oil
to all sliding and rotating surfaces.
• Replace all gaskets, O-rings and oil seals with
new parts.
1.
Assemble the piston and the connecting rod.
1)
Use a hydraulic press for installation.
2)
The piston front mark(A) and the connecting rod
front mark must face the timing belt side of the
engine.

2.
Install piston rings.
1)
Install the oil ring spacer and 2 side rails by hand.
2)
Using a piston ring expander, install the 2 com-
pression rings with the code mark facing upward.
3)
Position the piston rings so that the ring ends are
as shown.
