Description
Overview:
This piston pin is a core engine component for Robin Subaru EX13 petrol engines, linking the piston to the connecting rod to allow smooth reciprocating movement. It is manufactured from high-strength steel with a precision ground finish to handle constant combustion loads and sliding contact within the piston bosses and small end. By maintaining correct alignment and low friction at the piston-to-rod joint, it supports efficient running, stable idle, and reliable power delivery. Suitable for both professional and domestic users, it is commonly used in compactors, generators, pumps, and other machinery driven by the EX13. A sound piston pin helps reduce wear on the piston and con-rod, aiding overall engine longevity when paired with correct lubrication and service practices.
Key Features:
- Durable steel construction engineered for continuous cyclic loads and high temperatures
- Precision diameter and surface finish to promote stable oil film and low friction
- Accurate fit for the EX13 small-end and piston bosses to prevent knock and ovality
- Smooth running support that helps protect the piston, circlips, and connecting rod from premature wear
- Corrosion-resistant, polished exterior to aid assembly and long-term reliability
- Suitable for routine rebuilds and reactive repairs where the original pin shows wear or scoring
- Supports consistent performance when replacing a worn pin during ring, piston, or con-rod service
- Straightforward like-for-like replacement when used with the correct retainers and lubrication
- Compatible with typical small-engine workshop practices and tools
Typical Applications:
Used in Robin Subaru EX13 engines fitted to light construction and garden equipment, including plate compactors, generators, water pumps, pressure washers, tillers, and similar machinery. Ideal when refurbishing an engine that shows piston slap, small-end wear, or pin scoring, and as part of preventative maintenance during top-end overhauls.
Also known as:
Often referred to as a wrist pin, gudgeon pin, small-end pin, piston pin shaft, or piston connecting pin. These terms describe the same component that locates the piston to the con-rod and pivots during the engine cycle.
