At the heart of every durable HOWO or Sitrak diesel engine lies a network of precision components that work in perfect harmony. The 080V11302-0051 Intermediate Gear Pin is one such unsung hero — a small but critical pin that anchors the intermediate gear, ensuring flawless timing and power transfer between the crankshaft and camshaft. As a core element of authentic Howo/Sitrak truck parts, the 080V11302-0051 is manufactured to withstand extreme torsional loads, thermal cycling, and continuous vibration — delivering the kind of reliability that keeps fleets profitable and operators confident.
The 080V11302-0051 Intermediate Gear Pin is a precision-ground cylindrical shaft that serves as the fixed pivot for the intermediate gear in the timing gear train of SINOTRUK MC-series engines. It is engineered from high-grade alloy steel with a hardened surface and a tough core, providing excellent resistance to bending, shear, and surface fretting.
This pin is designed to maintain precise axial and radial alignment of the intermediate gear, which in turn drives the camshaft and fuel pump gears. Any deviation in pin geometry can lead to timing errors, increased gear noise, and premature bearing wear. The 080V11302-0051 eliminates these risks by adhering to the strictest OEM tolerances – with a diameter tolerance of ±0.005 mm and a surface roughness of Ra ≤ 0.4 µm.

Though it may appear simple, the 080V11302-0051 Intermediate Gear Pin performs four mission-critical roles that directly affect engine performance and longevity:
Without a robust intermediate gear pin like the 080V11302-0051, the entire timing train becomes unstable, leading to rough idling, reduced power, and potentially catastrophic engine failure.
The 080V11302-0051 Intermediate Gear Pin is engineered to be a direct replacement for the original factory pin used in SINOTRUK’s most popular commercial vehicle platforms. Its compatibility spans across multiple engine families and vehicle models, including:
This pin is also used in many special-purpose vehicles such as concrete mixers, dump trucks, and tractor units that rely on the MAN-technology engine platform. The 080V11302-0051 ensures that your engine’s timing remains factory-perfect, regardless of the operating environment.
The 080V11302-0051 Intermediate Gear Pin is produced using a multi-stage process that guarantees consistency and durability. Each batch starts with vacuum-degassed 20CrMo steel, which is then hot-forged to refine the grain structure. The key manufacturing steps include:
The result is a pin that not only meets but exceeds the original OEM specifications, providing a reliable foundation for the timing gear train over millions of engine cycles.
Replacing the intermediate gear pin is a straightforward procedure, but attention to detail is crucial. Follow these guidelines to ensure a trouble-free installation of the 080V11302-0051:
For preventive maintenance, inspect the pin for signs of fretting or corrosion during every major service interval (e.g., every 200,000 km). If the gear exhibits excessive axial play or abnormal noise, it may indicate pin wear. Replacing the 080V11302-0051 at the first sign of trouble can save you from costly gear and bearing failures.
Counterfeit and low-quality intermediate gear pins are widespread, but they carry serious risks. The genuine 080V11302-0051 distinguishes itself through:
Aftermarket pins often use mild steel, lack proper hardening, and have rough surfaces that accelerate wear on both the pin and the gear’s inner bushing. By choosing the 080V11302-0051, you secure the long-term reliability of your timing train and avoid unscheduled downtime.
We understand that a missing intermediate gear pin can halt an entire fleet. That’s why the 080V11302-0051 is stocked in multiple distribution hubs worldwide, ensuring rapid fulfillment for both urgent and planned maintenance. Each pin is packaged with protective measures:
With the 080V11302-0051, you receive not just a component but a complete support package – including detailed installation instructions and access to our technical team (non-contact).
In the demanding world of heavy-duty trucking, every component must earn its place. The 080V11302-0051 Intermediate Gear Pin has earned its reputation through years of field service, surviving extreme heat, constant vibration, and the relentless torque of high-output diesel engines. It is the pin that workshops choose for rebuilds and that OEM dealers recommend for preventive maintenance.
By selecting the genuine 080V11302-0051, you are not only replacing a worn part – you are restoring your engine’s timing precision, reducing gear noise, and preventing costly secondary failures. Combined with other authentic Howo/Sitrak truck parts, it forms the backbone of a reliable powertrain that delivers maximum uptime and minimum operating costs.
