Product Information

Full details

The Naraku C-Clip Mounting Tool (NK902.02) is designed for professional mechanics and home enthusiasts working on scooter or motorcycle engine builds. Its primary benefit is the simplification of installing 12 mm piston clips, which are notorious for being difficult and prone to flying off during manual installation. While this tool provides precision and ease, it is specifically sized for 12 mm clips, meaning it will not accommodate larger or smaller piston pin dimensions without potential damage to the component.

Extended Product Information

FAQs

Will this tool work on 10 mm piston pins?

No, this tool is specifically designed for 12 mm clips and will not provide the correct fit for 10 mm components.

Do I need special grease to use this?

Using a small amount of assembly lube on the clip can help it slide into the groove more smoothly.

Can this be used for other types of circlips?

This tool is optimized specifically for piston pin C-clips; it may not function correctly with flat washers or exterior shaft snap rings.

What is the material of the tool?

The tool is constructed from high-strength metal designed to withstand the stress of clip installation without deforming.

Does it work with flat-style and round-wire clips?

It is most effective with round-wire piston clips, which are standard for most 12 mm piston configurations.

Troubleshooting

Clip will not slide into the groove

Check the piston groove for carbon buildup or burrs and ensure the clip orientation matches the groove opening.

Clip pops out while installing

Ensure the tool is held flush against the piston face to prevent the clip from expanding prematurely during insertion.

Pros and Cons

Pros

  • Eliminates the frustration of manual clip installation
  • Prevents scratches and scoring on the piston wall
  • Ensures the clip sits perfectly flat in the groove
  • Compact size fits easily in any tool box
  • High-quality construction for long-term reliability

Cons

  • Limited to 12 mm diameter clips only
  • Requires proper alignment to prevent the clip from jumping
  • Does not replace the need for precision handling

Setup, Compatibility & Care

This tool is designed as a direct solution for 12 mm piston clips on most standard scooter and small-displacement motorcycle engines. Before use, ensure the piston groove is free of debris or old carbon deposits. To maintain the tool, simply wipe the conical tip with a light oil or grease before storage to prevent corrosion. Avoid using excessive hammer force; the tool is designed for manual pressure and precise guidance rather than high-impact installation.
