The piston pin (also known as the wrist pin) is a critical engine component that connects the piston to the connecting rod, transferring combustion forces to the crankshaft. For SINOTRUK Homan heavy-duty diesel engines, the OEM number FG610Y001323+008/1 identifies a high-strength, precision-ground piston pin engineered to withstand extreme mechanical loads and high temperatures. As a trusted supplier of Sinotruk Homan parts, Deruna offers this genuine piston pin, manufactured to the strictest OEM tolerances.
The FG610Y001323+008/1 piston pin is forged from high-grade case-hardened steel, featuring a precision-ground outer surface and a honed inner bore for optimal oil film retention. Its hollow design reduces reciprocating mass while maintaining exceptional shear and bending strength. Whether you are rebuilding an engine or replacing worn pins, this component delivers the durability and precision that SINOTRUK Homan engines demand.

The FG610Y001323+008/1 piston pin is a precision cylindrical component that serves as the pivot point between the piston and the connecting rod. It transmits the explosive force of combustion from the piston to the connecting rod, which then converts linear motion into rotational motion at the crankshaft. This pin is specifically engineered for SINOTRUK Homan heavy-duty diesel engines, offering exceptional strength, wear resistance, and fatigue life.
Manufactured from high-quality case-hardened alloy steel, the FG610Y001323+008/1 piston pin undergoes a multi-step heat treatment process that creates a hard, wear-resistant surface while maintaining a tough, ductile core. This combination provides outstanding resistance to galling, scuffing, and bending under the high loads and temperatures typical of diesel combustion. The pin’s outer diameter is precision-ground to a mirror finish, ensuring a perfect fit with the piston boss and connecting rod bushing.
Every FG610Y001323+008/1 piston pin is 100% inspected for dimensional accuracy, surface roughness, and hardness uniformity. The hollow bore is honed to a precise diameter, promoting optimal oil flow and reducing reciprocating weight. Choosing this genuine pin ensures minimal piston-to-cylinder wall clearance, reduced noise, and extended engine life.

All values are based on OEM engineering specifications for the FG610Y001323+008/1 piston pin. Minor variations may occur due to manufacturing tolerances.
The FG610Y001323+008/1 pin is forged from SAE 8620 alloy steel, carburized and hardened to provide a wear-resistant surface with a tough, ductile core that resists bending and fracture.
The outer surface is ground to a mirror finish with tight tolerances, ensuring a perfect fit with the piston boss and connecting rod bushing, minimizing clearance and reducing noise.
The hollow bore is honed to a precise diameter, promoting oil flow for effective lubrication and cooling, while reducing reciprocating mass for better engine response.
The hollow design of the FG610Y001323+008/1 pin reduces inertial forces, allowing higher engine speeds and reduced stress on the connecting rod and bearing.
The combination of case hardening and shot peening provides outstanding resistance to cyclic bending and shear stresses, ensuring long service life even under heavy loads.
With its superior wear resistance and precision fit, the FG610Y001323+008/1 piston pin reduces the need for frequent overhauls, lowering overall maintenance costs.
The piston pin operates under some of the highest mechanical and thermal stresses in the engine. A substandard pin can lead to piston seizure, connecting rod bearing failure, or catastrophic engine damage. The genuine FG610Y001323+008/1 piston pin eliminates these risks through OEM-grade materials, precision manufacturing, and strict quality control.
Benefits of choosing the authentic FG610Y001323+008/1 pin:
Deruna sources the FG610Y001323+008/1 piston pin from certified OEM suppliers, with each unit inspected for hardness, surface finish, and dimensional accuracy. We package each pin in protective sleeves to prevent surface damage during transit, so it arrives ready for installation.
Proper installation and maintenance of the piston pin are essential for engine reliability and longevity. Follow these best practices when working with the FG610Y001323+008/1 piston pin:
Before installation, inspect the FG610Y001323+008/1 pin for any nicks or scratches. Also check the piston boss and connecting rod small-end bore for wear or burrs. Clean all components thoroughly.
Apply clean engine oil or assembly lube to the pin’s outer surface and the bores of the piston and connecting rod before pressing or sliding the pin into place.
Always use a pin press or appropriate driver tool to install the FG610Y001323+008/1 pin. Never hammer directly on the pin, as this can damage the surface or cause distortion.
During major overhauls, inspect the FG610Y001323+008/1 pin for signs of scuffing, scoring, or discoloration. Replace if any damage is evident, even if wear appears minimal.
Always refer to the SINOTRUK Homan service manual for detailed piston and connecting rod assembly procedures, torque specifications for retaining rings (if applicable), and proper pin fitment clearances. Correct installation ensures optimal engine performance and maximum service life.
