The Bomag 05813057 Hydraulic Gear Motor is a genuine OEM component designed for a wide range of Bomag tandem rollers and BMP 8500 trench compactors. Sourced directly from Bomag, this hydraulic gear motor delivers an exact match to the original specification, ensuring proper integration with the machine's hydraulic drive system. Fitment covers an extensive lineup including BW 100, BW 115, BW 120, BW 124, BW 125, BW 131, BW 135, BW 141, BW 151, and BW 154 series machines, as well as the BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota trench compactors. When you need to restore full hydraulic drive performance, this motor is the correct replacement backed by Bomag's own parts program.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original displacement and pressure ratings, ensuring the motor delivers the correct torque and flow characteristics for your machine's drive circuit.
- Direct-Swap Replacement — matches the original port configuration, mounting flange, and shaft dimensions for straightforward installation without custom adaptation.
- Broad Tandem Roller Coverage — fits Bomag BW 100, BW 115, BW 120, BW 124, BW 125, BW 131, BW 135, BW 141, BW 151, and BW 154 tandem rollers across AC, AD, ACH, ADH, ACW, ADe, SL, AM, and CC variants, plus the BMP 8500, BMP 8500 Kohler, and BMP 8500 Kubota trench compactors.
- Restored Drive System Output — a worn or failed hydraulic gear motor causes sluggish drum drive, uneven compaction, or complete loss of propulsion; this genuine replacement restores full hydraulic output and consistent compaction performance.
- Verified Part Number Traceability — ordering by part number 05813057 confirms you are receiving the exact motor specified in Bomag's service documentation, eliminating guesswork on complex hydraulic assemblies.
A hydraulic gear motor converts hydraulic fluid pressure from the machine's pump into rotational mechanical output, driving the drum or propulsion system on the roller or trench compactor. It is a core element of the closed-loop hydrostatic drive circuit — when it wears internally, the machine loses drive efficiency, speed control becomes erratic, and in severe cases the drum stops turning entirely. Replacing a failing hydraulic gear motor promptly with a correctly specified unit protects the rest of the hydraulic circuit from contamination caused by internal wear debris.
