The Bomag 05800041 Control Piston is a genuine OEM component designed for the BW 212 D-2 single drum roller. Sourced directly from Bomag, this control piston meets the same specifications as the original part fitted at the factory, ensuring correct hydraulic system operation. If your BW 212 D-2 is exhibiting erratic response, loss of drive, or inconsistent compaction output, a worn or failed control piston is a likely culprit — and this is the correct OEM replacement to restore it. Order part number 05800041 with confidence knowing it is built to match the original in every dimension and material.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact tolerances for metering and pressure regulation, ensuring consistent hydraulic control response rather than the guesswork that comes with an imprecise fit
- Direct OEM Replacement — this control piston installs directly into the hydraulic control circuit of the BW 212 D-2, replacing the original component without modification or adaptation
- Confirmed Fitment — verified for the Bomag BW 212 D-2 single drum roller; always cross-reference part number 05800041 against your machine's serial number before ordering
- Restored Drive and Compaction Consistency — a correctly functioning control piston maintains precise hydraulic flow regulation, keeping drum speed and compaction force steady across varying load conditions
- Long-Term Hydraulic System Protection — an OEM-spec piston maintains proper clearances within the valve body, helping to prevent internal leakage that can accelerate wear on surrounding hydraulic components
The control piston is a precision hydraulic component that regulates fluid flow and pressure within the machine's hydraulic control circuit. By metering hydraulic oil to the appropriate actuators, it governs drive response and operational consistency — on a single drum roller like the BW 212 D-2, that means direct influence over drum rotation, travel speed, and compaction output. When a control piston wears or fails, operators typically notice sluggish or erratic machine response, uneven compaction performance, or a complete loss of drive function, making timely replacement critical to keeping the machine working as intended.
