The Bomag 05800345 Control Piston is a genuine OEM component designed for BW-series single drum rollers and tandem rollers, including the BW 172 D-2, BW 212 D-2, BW 212 D-3, BW 184 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2. Sourced directly from Bomag, this control piston is manufactured to the same exacting standards as the original, ensuring a direct drop-in fit with no guesswork. Confirm your model and part number 05800345 against your machine's service documentation before ordering to ensure correct application.
Key Features
- Genuine OEM Precision — manufactured by Bomag to exact hydraulic tolerances, ensuring consistent spool movement and pressure response critical to a control piston's function
- Direct-Fit Replacement — matches the original component's dimensions and port geometry for a straightforward installation into the hydraulic circuit
- Broad Model Coverage — fits BW 172 D-2, BW 212 D-2, BW 212 D-3, BW 184 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2 single drum and tandem rollers
- Hydraulic System Integrity — a correctly functioning control piston maintains precise flow and pressure regulation; a worn or damaged piston can cause erratic drive response, loss of compaction force, or uncontrolled roller movement
- Operational Safety — proper control piston function is essential for predictable machine response; replacing a failed piston restores accurate operator control over drive and vibration circuits
The control piston is a precision hydraulic component that regulates fluid flow and pressure within the roller's hydrostatic drive or vibration system. By shifting position in response to operator input or system pressure signals, it directs hydraulic oil to the appropriate actuators — controlling drum speed, direction, or vibration amplitude. When the control piston wears, sticks, or fails, the machine may exhibit sluggish or unpredictable response, reduced compaction output, or an inability to hold consistent travel speed, making timely replacement essential to safe and productive operation.
