Description
Overview:
The piston pin is a precision-ground metal component that links the piston to the connecting rod at the small end, allowing smooth pivoting through the engine cycle. This pin is designed for Robin/Subaru single-cylinder petrol engines, specifically the EH30 and EH34, which are commonly found in construction and garden machinery. Built for high strength and consistent fit, it supports reliable combustion and reduces wear at the piston and rod interface. Manufactured to match OEM No. 246-23301-03, it helps restore correct clearances and alignment when replacing worn or damaged pins. Suitable for workshop maintenance or planned overhauls, it is a practical, direct-fit solution that helps keep equipment running efficiently and within specification.
Key Features:
- High-strength steel construction for dependable load-bearing and wear resistance
- Precision sizing to meet OEM No. 246-23301-03 for correct fit in EH30 and EH34 engines
- Smooth, ground surface to support proper lubrication and reduce friction
- Helps maintain piston alignment, lowering the risk of scuffing and noise
- Stable performance under heat and cyclic loading typical of small petrol engines
- Straightforward replacement using standard workshop tools
- Supports consistent compression and combustion for reliable engine output
- Suitable for both routine servicing and full engine rebuilds
Typical Applications:
Used in Robin/Subaru EH30 and EH34 engines fitted to equipment such as plate compactors, generators, water pumps, concrete tools, tillers, and other garden or light construction machinery. Ideal when refurbishing the top end, addressing piston slap, or replacing worn small-end components to restore smooth operation and extend engine life.
