The WG2211040207 (04107 / 040067) 5th Gear is a precision-engineered transmission gear designed for heavy-duty truck gearboxes.
It is widely used in manual transmission systems for commercial vehicles, ensuring stable power transmission in 5th gear operation. Manufactured to strict OEM standards, it delivers high durability, smooth engagement, and reliable performance under heavy-load conditions.
Key Function
- Ensures stable power transmission in 5th gear position
- Provides smooth and efficient gear engagement
- Maintains precise matching with gearbox shaft system
- Reduces vibration and operational noise
Product Advantages
● High Hardness & Wear Resistance
The gear is manufactured using carburizing and quenching heat treatment, followed by low-temperature tempering and precision grinding. The surface hardness reaches HRC 58–63, providing:
- Excellent wear resistance
- Strong impact resistance
- Reduced risk of tooth breakage and deformation
It performs reliably under long-term heavy-duty operation.
● Precision Engineering for Smooth Operation
The gear is processed with high-precision machining standards, ensuring:
- Strict OEM-compliant tooth profile, module, and pressure angle
- Accurate meshing with transmission shaft system
- Smooth operation without jamming or vibration
This guarantees stable and efficient gearbox performance.
● Helical Gear Design for Low Noise
The gear adopts a helical tooth design, offering:
- Smoother meshing process
- Lower operating noise
- Improved load distribution
This significantly enhances driving comfort and transmission efficiency.
● Enhanced Fatigue & Durability Performance
Through advanced surface strengthening treatment, the gear provides:
- High fatigue resistance
- Long service life under continuous load
- Stable performance in harsh working conditions
It effectively reduces maintenance frequency and operating costs.
● Dynamic Balance for Stable Operation
Each gear undergoes strict dynamic balancing calibration, ensuring:
- No vibration during high-speed operation
- No abnormal noise
- Stable and reliable performance
This protects the gearbox system and extends service life.
