The Bomag 05818166 Gear Motor is a genuine OEM component designed for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers. Sourced directly from Bomag, this gear motor meets the exact specifications of the original unit it replaces, ensuring a direct, correct-fit installation without adaptation. Whether you're servicing a BW 900 AD or a BW 900-2, part number 05818166 is the authoritative OEM replacement to restore full hydraulic drive function.
Key Features
- Genuine OEM Hydraulic Precision — Built to Bomag's original displacement and torque specifications, ensuring consistent hydraulic output that an aftermarket unit may not match.
- Direct OEM Replacement — Mounts to the existing hydraulic circuit and drive assembly on the BW 900 AD and BW 900-2 using the original porting and bolt pattern — bolt-on installation.
- Confirmed Fitment — Verified for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers, covering both equipment classes in the BW 900 family.
- Sustained Drive Performance — A properly functioning gear motor maintains steady drum rotation and travel speed; a failing unit causes sluggish drive, overheating hydraulic fluid, and uneven compaction results.
A gear motor converts hydraulic flow from the machine's pump into rotational mechanical force, driving the drum or wheel assembly at controlled speed and torque. On compaction equipment like the BW 900 series, the gear motor is central to drum drive performance — if it wears internally or develops internal leakage, the machine loses drive power, travel becomes inconsistent, and compaction quality suffers. Replacing a failed gear motor with a genuine Bomag unit restores the hydraulic efficiency and mechanical output the machine was designed to deliver.
