Cylinder Block: Assembly: Piston

Install new snap ring on one side of piston pin hole.
Heat piston to 60 to 70°C (140 to 158°F) and assemble piston piston pin, connecting rod and new snap ring.
- Align the direction of piston and connecting rod.
- Numbers stamped on connecting rod and cap correspond to each cylinder.
- After assembly, make sure connecting rod swings smoothly.
Set piston rings as shown.

CAUTION:

When piston rings are not replaced, make sure that piston rings are mounted in their original positions.
When replacing piston rings, those without punchmarks present can be mounted with either side up.
Align piston rings so that end gaps are positioned as shown in the figure.
