Pistons, Piston Rings, Connecting Rods and
Cylinders Disassembly and Assembly
Disassembly
1) Using piston ring expander, remove two
compression rings (Top and 2nd) and oil ring from
piston.
2) Remove piston pin from connecting rod as follows.
a) Ease out piston pin circlips (1), as shown.
b) Force piston pin out.
Assembly
1) Decarbonize piston head and ring grooves using a
suitable tool.
2) Install piston pin to piston (1) and connecting rod (2):
a) After applying engine oil to piston pin and piston
pin holes in piston and connecting rod.
b) Installing connecting rod to piston.
NOTE
Be sure to position front mark (4) on piston
and oil hall (5) of connecting rod at specified
position as shown in figure.
c) Insert piston pin to piston and connecting rod.
d) Install piston pin circlips (3).
NOTE
Circlip should be installed with its cut part
S6RW0D1406033
facing as shown in figure. Install so that
circlip end gap comes within such range as
indicated by arrow.
3) Install piston rings to piston:
• As indicated in figure, 1st and 2nd rings have "T"
mark (4) respectively. When installing these piston
rings to piston, direct marked side of each ring

toward top of piston.
• 1st ring (1) differs from 2nd ring (2) in thickness,
shape and color of surface contacting cylinder
wall.
Distinguish 1st ring from 2nd ring by referring to
