FAQ

    Which of the two VIAB generations is built into my vehicle?

    • VIAB 433D in the Actros MP3 (WDB 934…)
    • VIAB 434D in the Actros new, Arocs, Antos (WDB 963... and WDB 964…)as well as Manitowoc mobile cranes

    Why may only 75W-90 multi-purpose transmission fluid be used in manual transmissions in conjunction with VIAB?

    The VIAB freewheel is lubricated with transmission fluid. The 75W-90 multi-purpose transmission fluid ensures the freewheel function even at low temperatures.

    Why is a teach-in process required for the VIAB 434D?

    The engine and VIAB work together closely in the vehicle. The engine and VIAB torques are subject to tolerances. To coordinate them the VIAB 434D and engine teach-in process includes both. The VIAB control unit contains the compensation factors.

    When does the teach-in process have to be performed for the VIAB 434D?

    After a SW update in the VIAB control unit, after replacement of the control unit in the vehicle, after replacement of the VIAB assembly in the vehicle.

    How can the teach-in process be started?

    The teach-in process can only be started with the Daimler XENTRY diagnostic tool. The process is fully automated and takes place with the transmission in neutral and the engine running.

    Why is it so important to maintain the precise oil level with the VIAB?

    The space for oil and air in the VIAB assembly are precisely coordinated. An oil level that is too high or too low can result in oil foam that can seep out of the VIAB assembly with the exhaust. The oil is ejected as a result. For this reason, the oil level must be checked any time a leak is suspected. The extremely narrow oil fill quantity tolerance when replacing the oil (7.5 ± 0.3 l for VIAB 433D and 9.4 l ± 0.3 l for VIAB 434D) is due to this situation.
