Use the crank bore codes and crank journal codes to
select the appropriate replacement bearings from the
following table.
NOTE
• Color code is on the edge of the bearing. Refer to
the table in the step 6 of the main bearing clear-
ance inspection.
• When using bearing halves of different colors, it
dose not matter which color is used in the top or
bottom.

ROD BEARING SELECTION
1.
Inspect each connecting rod for cracks and heat dam-
age.
Connecting Rod Big End Bore Code Locations
2.
Each rod has tolernance range from 0 to 0.018mm
(0.0007in.), in 0.006mm (0.0002in.) increments, de-
pending on the size of its big end bore.
It’s then
stamped with a letter (A, B or C) indicating the range.
You may find any combination of letters in any engine.
If you can’t read the code because of an accumulation
of oil and varnish, do not scrub them with a wire brush
or scraper. Clean them only with solvent or detergent.

PISTON, PIN AND CONNECTING ROD
1.
Apply engine oil to the piston pin snap rings and turn
them in the ring grooves.
NOTE
Take care not to damage the ring grooves.
2.
Remove both snap rings(A) carefully so they do not
go flying or get lost. Wear eye protection.

3.
Remove the piston pin and the conecting rod assem-
bly.
4.
Measure the diameter of the piston pin.
Piston Pin Diameter
Standard (New)
27.995 ~ 28.000mm (1.1022 ~ 1.1024in.)
ACIE134A
NOTE
Inspect the piston, piston pin and connecting rod
when they are at room temperature.
5.
Set a snap ring in one side of piston pin hole.
6.
Before inserting the piston pin, apply a sufficient
amount of the lubricant oil to the outer surface of the
piston, the inner surface of the piston pin hole and
the small end bore of the connecting rod.
7.
Insert the piston pin(A). Assembly the piston and con-
necting rod with the embossed front marks on the
same side.

ACIE133A
NOTE
The front mark of the piston is embossed on the piston
whereas some letters are located on a side surface of
the connecting rod as the front mark.
CAUTION
• Be sure to keep the small end bore, piston
pin hole and piston pin undamaged and un-
scratched when inserting the piston pin.
• Set the snap rings to be sure for contacting
with the groove of the piston pin hole.

PISTON RING
1.
Using a piston, push a new ring into the cylinder bore.
ACIE137A
2.
Measure the piston ring end-gap(B) with a feeler
gauge :
• If the gap is too small, check to see if you have
the proper rings for your engine.
• If the gap is too large, recheck the cylinder bore
diameter against the wear limits.
If the bore is over the service limit, the cylinder
block must be rebored.
Piston Ring End-Gap
Top ring
Standard (New) : 0.25 ~ 0.40mm (0.0098 ~ 0.0157in.)
Second Ring
Standard (New) : 0.40 ~ 0.60mm (0.0157 ~ 0.0236in.)
Oil Ring
Standard (New) : 0.20 ~ 0.40mm (0.008 ~ 0.016in.)
3.
After installing a new set of rings, measure the ring-to-
groove clearances :
Top Ring Clearance
Standard (New)
0.083 ~ 0.137mm (0.0033 ~ 0.0054in.)
ACIE135A
Second Ring Clearance
Standard (New)
0.065 ~ 0.110mm (0.00256 ~ 0.00433in.)
Oil Ring Clearance
Standard (New)
0.03 ~ 0.07mm (0.00118 ~ 0.00275in.)
