Powertrain: Engine, Transmission and Axles

The SITRAK G7S 540 Tractor with Hub Reduction Axles is equipped with SINOTRUK’s proven “golden powertrain,” delivering outstanding power, reliability, and fuel efficiency.

1. Engine

Powered by the MC13.54-50 MAN-Technology Engine, producing 540 horsepower and manufactured at the MAN-SINOTRUK joint venture facility, the engine delivers exceptional performance and durability for demanding heavy-duty applications.

2. Transmission

The tractor equipped with the HW25712XSTL/HW25712XSTCL manual transmission, featuring:

• Maximum input torque of 2,500 Nm.
• Helical gear design for smoother operation.
• Dual countershaft architecture.
• Synchronizers and power-assisted shifting mechanism.

The aluminum transmission housing provides superior heat dissipation while enhancing durability and operational stability.

3. Axles

• Front Axle: MAN-Technology HF VGD95 Front Axle.
• Rear Axles: MCP16ZG Cast Hub Reduction Drive Axles.

These latest-generation MAN-Technology axles utilize advanced materials and engineering solutions, offering high torque capacity, outstanding durability, and exceptional operational stability under heavy loads.

The drivetrain configuration is designed to meet diverse customer requirements across the most demanding operating conditions.

Chassis System – The benchmark for Strength and Stability

The chassis frame of the G7S 540 Hub Reduction Tractor is engineered and manufactured according to SINOTRUK standards and technologies.

Constructed from high-strength carbon steel with excellent resistance to bending and torsional forces, the chassis is further optimized using advanced CAE (Computer-Aided Engineering) simulation tools. The triple-layer frame structure measures 300 × 80 × (8+8+8) mm, providing exceptional load-bearing capability while maintaining a relatively low curb weight.

The vehicle is also equipped with a V-Rod suspension system, a configuration widely recognized and trusted in the Vietnamese market. This design improves overall chassis stability, reduces side-to-side oscillation differences, enhances load distribution between the axles and frame, and contributes to increased durability and service life.
