The 080V04501-5013 camshaft gear assembly is a fundamental component of the engine’s timing system, responsible for driving the camshaft(s) in precise synchronisation with the crankshaft. Its primary function is to transmit rotational power from the crankshaft to the camshaft, ensuring that the intake and exhaust valves open and close at the correct times relative to piston position. In heavy‑duty diesel engines, accurate camshaft timing is essential for optimising volumetric efficiency, combustion quality, and emissions performance. A worn or damaged camshaft gear can lead to timing drift, loss of power, increased fuel consumption, excessive noise, and even valve‑to‑piston contact. By installing the genuine 080V04501-5013 camshaft gear assembly, you restore factory‑specified timing accuracy, ensuring reliable engine operation and maximum performance.

The 080V04501-5013 camshaft gear assembly is a direct replacement for the original component used in a wide range of HOWO and Sitrak heavy‑duty diesel engines. It is a critical part of the timing gear drive system and is commonly specified for:
The 080V04501-5013 camshaft gear assembly is manufactured to the highest quality standards, ensuring it outperforms generic aftermarket alternatives. Forged from premium alloy steel and precision‑heat‑treated to achieve optimal hardness and toughness, this gear offers exceptional resistance to wear, fatigue, and deformation under high‑load conditions. The gear teeth are ground to exacting tolerances, ensuring smooth, quiet engagement with the crankshaft and idler gears. The assembly is dynamically balanced to minimise vibration and reduce stress on the camshaft bearings and drive system. Each gear is inspected for tooth profile, hardness, and dimensional accuracy to guarantee compliance with OEM specifications. This commitment to quality translates into reliable camshaft timing, reduced noise and vibration, and extended engine service life.
Precision Gear Grinding
Teeth are ground to sub‑micron accuracy for smooth, quiet operation and reduced wear.
Advanced Heat Treatment
Hardened tooth surfaces and tough core provide exceptional wear resistance and fatigue strength.
100% Dimensional Inspection
Every gear is verified against OEM drawings to guarantee perfect fit and function.
Genuine OEM Quality
Built to Sinotruk’s original specifications – guaranteed performance and reliability.
Installing the 080V04501-5013 camshaft gear assembly requires careful attention to cleanliness, timing marks, and proper torque. Always refer to the appropriate workshop manual for your HOWO or Sitrak model. Before installation, thoroughly clean the camshaft nose and the gear bore, removing any debris, old sealant, or burrs. Heat the gear evenly to approximately 80‑100°C using an induction heater or oil bath to facilitate expansion for a shrink‑fit installation. Align the timing marks on the camshaft gear with those on the crankshaft gear and idler gear to ensure correct valve timing. Slide the gear onto the camshaft, ensuring it is fully seated against the shoulder. Tighten the retaining bolt to the specified torque (typically 250‑300 Nm, depending on engine variant). After installation, rotate the crankshaft two full revolutions and re‑check the timing marks to confirm correct alignment. During routine maintenance, inspect the gear teeth for signs of wear, pitting, or damage, and replace if necessary.
Choosing the 080V04501-5013 genuine camshaft gear assembly is an investment in the long‑term reliability and performance of your HOWO or Sitrak engine. Inferior aftermarket gears often use lower‑grade materials, imprecise tooth profiles, and inadequate heat treatment – leading to premature wear, timing drift, and costly engine damage. By using a genuine OEM component that adheres to Sinotruk’s exacting standards, you guarantee perfect fitment, accurate camshaft timing, and maximum durability. Fleet operators and workshop professionals worldwide trust this gear to maintain the integrity of their engines, reduce unplanned downtime, and lower overall maintenance costs. With its proven quality and reliability, it is the definitive choice for those who demand excellence.
