Description
Overview:
The Piston Pin - Robin Part - RB243 23301 03 is the hardened steel pin that joins the piston to the connecting rod in a small petrol engine. It provides the pivot point for the piston's movement, transferring combustion forces while keeping the assembly aligned and running smoothly. Built for high load and temperature, the pin resists wear and deformation to help maintain consistent engine performance. It is suitable for many construction and garden machines using Robin/Subaru-type engines, such as plate compactors, generators, water pumps, lawn mowers, and tillers. Precision-ground surfaces support low friction and reliable lubrication at the small end. This part is intended as a direct replacement during routine maintenance or a top-end rebuild to restore correct clearances and reduce piston slap and related noise.
Key Features:
- Hardened, high-strength steel for durability under continuous load and heat
- Precision-ground diameter and finish for smooth oscillation and reduced friction
- Direct replacement pattern for Robin/Subaru small-engine applications
- Helps maintain piston alignment, improving running smoothness and longevity
- Suitable for demanding site and garden use where vibration and dirt are common
- Supports reliable operation in both splash- and pressure-lubricated engines
- Straightforward to fit with standard workshop tools when following the service manual
- Stable performance helps protect the piston, small-end bearing/bush, and cylinder from premature wear
Typical Applications:
Used during engine repairs or scheduled overhauls on compactors, generators, pumps, cutters, lawn mowers, cultivators, and similar equipment. Ideal when addressing small-end wear, piston slap, or play at the connecting rod, and when replacing piston rings or bearings to restore smooth, efficient running and dependable starting.
Also known as:
Gudgeon pin, wrist pin, small-end pin, piston wrist pin, piston gudgeon, piston pivot pin. These terms refer to the same component that connects the piston to the connecting rod and allows the piston to articulate during the engine cycle.
