The Bomag 05819031 Travel Motor is a genuine OEM component designed for BW 138 AD-5, BW 138 AC-5, and BW 135 AD-5 tandem rollers. As a direct factory replacement, this travel motor delivers the exact hydraulic displacement, porting configuration, and mounting dimensions required by these machines. Sourcing a genuine OEM part ensures the drivetrain performs exactly as Bomag engineered it, with no risk of mismatched output or fitment issues. If your tandem roller is showing signs of sluggish propulsion, loss of tractive effort, or hydraulic fluid loss at the drive motor, this is the correct replacement to restore full operation.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact displacement and pressure ratings, ensuring the hydraulic circuit operates within its designed parameters rather than compensating for an under-spec motor
- Direct-Mount Replacement — matches the original bolt pattern, shaft dimensions, and port locations on BW 138 AD-5, BW 138 AC-5, and BW 135 AD-5 tandem rollers for a straightforward swap
- Verified Tandem Roller Fitment — confirmed for the BW 138 AD-5, BW 138 AC-5, and BW 135 AD-5, covering key variants in Bomag's tandem roller lineup
- Full Tractive Force Restored — a worn or failed travel motor causes loss of drive power, uneven drum propulsion, and poor maneuverability on grade; this genuine replacement brings propulsion back to full rated output
- Hydraulic System Integrity — proper internal sealing and clearances prevent cross-port leakage that can damage pumps and other downstream hydraulic components if left unchecked
The travel motor is a hydraulic drive unit that converts pressurized fluid from the machine's hydraulic pump into rotational force, propelling the roller drums forward and in reverse. On Bomag tandem rollers, the travel motor is central to both ground speed control and smooth drum synchronization across different compaction passes. When the travel motor degrades — through internal seal wear, piston or valve plate damage, or excessive internal leakage — the machine loses propulsion efficiency, may pull to one side, or becomes unable to maintain consistent travel speed, directly compromising compaction quality and operator control.
