Piston Pin 191970 – Diesel Engine Piston Connecting Pin

The Piston Pin 191970 is a mechanical component designed for compatible diesel engine piston assemblies. It connects the piston to the connecting rod, allowing the rod to pivot as the piston moves inside the cylinder. As a result, this component helps transfer combustion force to the crankshaft. Always verify the part number and engine application before ordering.

⭐ Key Features

The piston pin provides a pivotal connection between the piston and connecting rod. Its design supports smooth articulation as the piston travels through the cylinder. Furthermore, a correctly fitted pin helps maintain proper alignment within the piston assembly. Replacing a worn or damaged pin can help restore reliable operation when the surrounding components are also in suitable condition.

⚙️ Technical Insights

During engine operation, the piston pin transfers force between the piston and connecting rod while allowing relative movement. Therefore, correct fit and surface condition are essential for reliable performance. Before installation, inspect the pin bore, connecting rod bushing, and related components for wear or damage. Always confirm the required specifications and installation method using the relevant service documentation.

🛠 Application Scenarios

This component is intended for compatible diesel engine servicing and overhaul work. For example, technicians may inspect or replace the piston pin when rebuilding a piston assembly or addressing excessive clearance. However, similar symptoms can result from wear in other components. For this reason, inspect the complete assembly and verify compatibility before selecting a replacement.
