The Bomag 05904630 Gear Unit for Travel is a genuine OEM component designed for the BW 203 AD-4 AM tandem roller. Sourced directly from Bomag, this gear unit is built to the same specification as the original, ensuring a direct, compatible fit without the guesswork of aftermarket alternatives. This part is confirmed for the BW 203 AD-4 AM, making it the correct choice when restoring or maintaining the travel drive system on that machine.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original drive system tolerances, ensuring the gear unit delivers the correct torque transfer and engagement characteristics for the travel drive
- Direct-Fit Replacement — engineered to match the original mounting configuration and gear interfaces of the BW 203 AD-4 AM, allowing straightforward installation without custom adaptation
- Confirmed Fitment — verified for the BW 203 AD-4 AM tandem roller; use part number 05904630 to confirm compatibility before ordering
- Restored Drive Performance — a correctly functioning travel gear unit maintains smooth, consistent machine propulsion; a worn or failed unit can cause sluggish travel response, uneven drum speed, or complete loss of self-propulsion
- Long-Term Drivetrain Integrity — OEM gear geometry and material grades resist wear under the continuous load demands of asphalt compaction work, protecting surrounding drivetrain components from accelerated stress
The gear unit for travel is a core element of the machine's propulsion system, responsible for transmitting power from the hydraulic drive to the drum or wheel assembly that moves the roller forward and in reverse. It converts and regulates rotational force to deliver controlled, consistent travel speed across varying compaction loads. When this unit wears or fails, the machine may exhibit erratic movement, reduced travel speed, or an inability to propel itself — directly interrupting compaction work and placing additional strain on connected hydraulic and mechanical components.
