Description
Overview:
The piston pin for Robin/Subaru EH25 engines links the piston to the connecting rod so the piston can pivot smoothly through each stroke. It is a robust, high-quality metal pin designed to cope with engine heat, load, and vibration in demanding construction and garden machinery. As a direct replacement for OEM No. 270-23301-03, it provides the correct fit for reliable operation and helps maintain engine performance over time. Suitable for routine overhauls or repairs, this pin is chosen when the original shows wear, scoring, or ovality that can lead to noise, poor running, or accelerated component wear. Ideal for equipment powered by the EH25, including compactors, generators, pumps, and similar small plant and garden machines.
