The Bomag 05802839 Gear Motor is a genuine OEM component designed for Bomag BM-series cold milling machines, including the BM1000/30-2, BM1200 30-2, BM1300/30-2, BM 1200/30, and BM 1300/30. As a direct OEM replacement sourced through Bomag's authorized parts network, this gear motor meets the original design specifications for these heavy-duty planers. Confirmed fitment across the BM 1000, BM 1200, and BM 1300 cold milling machine families makes part number 05802839 a straightforward, confident choice for fleet managers and service technicians keeping these machines productive.
Key Features
- Genuine OEM Hydraulic Output Spec — manufactured to Bomag's original torque and flow requirements for this gear motor application, ensuring the hydraulic circuit performs as designed
- Direct-Mount Replacement — matches the original port configuration and mounting pattern, so this gear motor installs directly into the existing hydraulic circuit without adapter fittings or rework
- Broad BM-Series Coverage — confirmed for BM1000/30-2, BM1200 30-2, BM1300/30-2, BM 1200/30, and BM 1300/30 cold milling machines
- Sustained Milling Drive Integrity — a correctly functioning gear motor maintains consistent hydraulic power delivery to the milling drum drive system; a worn or failing unit causes loss of torque, erratic drum speed, and uneven cut depth
- Authorized OEM Sourcing — supplied as a genuine Bomag part, carrying the full confidence of OEM traceability and part number 05802839 verification
A gear motor converts hydraulic fluid flow and pressure into rotational mechanical output, serving as a key driver within the hydraulic circuit of a cold milling machine. On BM-series planers, this component delivers the torque needed to power auxiliary or primary drive functions tied to the milling drum and cutting system. When a gear motor begins to wear — through internal seal degradation, gear scoring, or volumetric efficiency loss — the machine suffers reduced drum power, inconsistent milling depth, and potential overheating of the hydraulic system. Replacing a failing gear motor promptly restores full hydraulic torque output and protects downstream components from the strain of an underperforming circuit.
