The Bomag 05901320 Gear Unit for Travel is a genuine OEM component designed for BW 190 AD-4 AM and BW 203 AD-4 AM tandem rollers. Sourced directly from Bomag, this gear unit delivers the exact specifications required to restore proper machine propulsion without adaptation or guesswork. It is the correct OEM replacement for operators and fleet managers who depend on these tandem rollers to stay productive on asphalt paving and compaction work.
Key Features
- OEM-Matched Gear Tolerances — manufactured to Bomag's exact gear ratio and torque specifications, ensuring the travel drive performs as the machine was originally engineered to deliver
- Direct-Fit Replacement — engineered to mount directly into the BW 190 AD-4 AM and BW 203 AD-4 AM tandem roller drive system using the original bolt pattern and interface
- Confirmed Fitment — verified compatibility with Bomag BW 190 AD-4 AM and BW 203 AD-4 AM tandem rollers; part number 05901320 matches the OEM catalog specification for these models
- Consistent Travel Performance — a properly functioning gear unit maintains smooth, responsive machine movement across the drum; a worn or failing unit causes erratic travel, loss of traction control, and premature drivetrain wear
- Genuine Bomag Quality — produced under Bomag's OEM standards for material grade and gear hardness, giving this unit the service life expected from original-equipment drivetrain components
The gear unit for travel is a core drivetrain component that transfers power from the hydraulic motor to the drum or wheel assembly, controlling how the roller moves forward and in reverse across the work surface. On tandem rollers like the BW 190 AD-4 AM and BW 203 AD-4 AM, precise gear engagement is critical to maintaining even compaction passes and consistent ground speed. When this unit wears or fails, operators typically notice sluggish travel response, unusual noise from the drive system, or a complete loss of propulsion — all of which require immediate attention to prevent further drivetrain damage.
