CAUTION
• The end faces of the oil ring are plated with
hard chrome. When you install the piston into
the cylinder, do not give a damage to the
cylinder by the oil ring. If the ring's planting is
scratched, it may get stuck on the cylinder wall,
causing serious damage.
IMPORTANT
• Put a mark on the connecting rod and the
piston with the same number to keep the same
combination.
1. Put the piston fully in 80 ℃ (176 ℉ ) oil for 10 to 15
minutes.
2. Install the piston pin (4) and the connecting rod (2)
to the piston (1).
