Powerhouse for the Mercedes-Benz Citaro C2

In the world of public transport, reliability is the most important currency. For workshop managers and bus operators running the Mercedes-Benz Citaro C2 (Euro 6), the rear axle is a critical component. The ZF AV 133/87 (Parts list number 4472037311, OE No. A6443501101) represents the gold standard for low-floor buses.

Technical Precision for Urban Traffic

The AV 133 is what is known as an inverted portal axle. This specific design is the prerequisite for modern low-floor concepts. Because the central axle housing is offset, it creates a continuously flat center aisle throughout the bus. This allows passengers barrier-free access—a must-have for modern urban transit.

With a ratio of i = 6.20, this model is specifically designed for the demands of metropolitan areas. This short ratio ensures high starting torque and efficient acceleration in heavy stop-and-go traffic, while minimizing the thermal load on the components.

Application in the Mercedes-Benz Citaro C2

The Mercedes-Benz Citaro C2 is one of the most successful bus models worldwide. Since the introduction of the Euro 6 standard in 2013, the demands on the chassis have increased due to the higher weight of exhaust after-treatment systems. The ZF AV 133/87 was developed precisely for these load collectives. It offers a maximum axle load of up to 13 tons and is optimized for the integration of modern disc brake systems.

Sustainability through Overhauling

Replacing a unit with a brand-new component is often economically unfeasible, especially for vehicles that already have high mileage. This is where Möller-Scholz provides an efficient solution: a completely overhauled rear axle.

During the overhauling process, only original ZF spare parts are used. This guarantees that tolerances and material qualities meet the manufacturer’s exact specifications. With a one-year warranty and no mileage limit, this axle provides the security of a new part at a fraction of the cost.
