The Bomag 05818821 Travel Motor is a genuine OEM component designed for BW 177 D-4, BW 145 D-40, and BW 177 D-50 single drum rollers. Sourced directly from Bomag, this travel motor meets the same specifications as the original unit installed at the factory, ensuring a direct, compatible replacement for your machine. Verified fitment across these single drum roller models means you can order with confidence, knowing part number 05818821 is the correct component for your application.
Key Features
- Genuine OEM Hydraulic Precision — Built to the exact displacement and pressure tolerances of the original unit, ensuring the hydraulic drive circuit performs as designed in your single drum roller.
- Direct Replacement Fit — Matches the original mounting configuration and port layout, so this travel motor installs directly into your machine without modifications to hydraulic lines or mounting hardware.
- Confirmed Single Drum Roller Compatibility — Fits BW 177 D-4, BW 145 D-40, and BW 177 D-50 single drum rollers; verified against Bomag's OEM parts catalog using part number 05818821.
- Sustained Propulsion Performance — A properly functioning travel motor delivers consistent tractive force and ground speed control, keeping compaction passes smooth and productive across the full operating range.
- Hydraulic System Integrity — Manufactured to OEM sealing and clearance standards, this motor resists internal leakage that can cause sluggish travel response, overheating, and progressive hydraulic system damage.
The travel motor is the hydraulic component responsible for converting pressurized fluid from the machine's hydraulic system into rotational force that drives the roller's wheels or drum, propelling the machine forward and in reverse. On a single drum roller like the BW 177 D-4 or BW 145 D-40, the travel motor works continuously under load, and wear or internal leakage will cause a noticeable loss of drive power, erratic ground speed, or complete loss of propulsion. Replacing a worn or failed travel motor with a genuine OEM unit restores full hydraulic drive performance and protects the surrounding hydraulic circuit from the contamination and pressure imbalances a failing motor can introduce.
