Description
Overview:
This piston pin is a precision-engineered internal engine component for small petrol engines used in construction and garden machinery. Made from hardened alloy steel with a smooth, ground finish, it connects the piston to the connecting rod at the small end, allowing the piston to pivot cleanly through each stroke. The robust build resists wear, heat, and impact loads typical of compact engines running under continuous duty. Suitable for selected Robin/Subaru small engines found in generators, pumps, plate compactors, mowers, and similar equipment, it helps restore tight clearances and stable operation during rebuilds or preventative maintenance. Correct fitment of a quality piston pin supports reliable starting, steady compression, reduced friction, and longer service life of associated parts such as the small-end bush or needle bearing.
Key Features:
- Hardened alloy steel construction for long service life in demanding conditions
- Precision-ground diameter for accurate fit and smooth articulation at the small end
- High surface finish reduces friction and wear on the bush or needle bearing
- Stable under high temperatures and repeated load cycles common in compact engines
- Helps maintain correct piston alignment to minimise noise and piston slap
- Supports consistent compression and power delivery after overhaul or repair
- Compatible with typical circlip/retainer arrangements used on small engines
- Tight tolerances aid easy, predictable installation with minimal downtime
- Corrosion-inhibiting oil film for protection during storage and handling
- Suitable for routine maintenance programmes in hire fleets and professional use
Typical Applications:
Used during engine rebuilds, piston replacements, or small-end bush/bearing servicing on equipment such as generators, water pumps, plate compactors, lawn mowers, scarifiers, tillers, and concrete tools. Ideal for tradespeople, grounds teams, and DIY users looking to restore smooth piston motion, reduce wear, and improve reliability on Robin/Subaru-powered machines.
Also known as:
Wrist pin, gudgeon pin, piston wrist pin, small-end pin, floating pin, piston connector pin. These terms refer to the same component that links the piston to the connecting rod at the small end and permits controlled pivoting during the engine cycle.
