The Bomag 05817652 Servo Piston is a genuine OEM component designed for Bomag single drum rollers across a wide range of BW 200-series and C 850-series machines. Sourced directly from Bomag, this servo piston meets the exact engineering specifications required for proper hydraulic drive system operation. This part fits an extensive lineup including BW 211, BW 212, BW 213, BW 214, BW 215, BW 216, and C 850 C single drum rollers across the -3, -4, -40, -4i, and -50 generation variants. When your machine needs a servo piston replacement, using part number 05817652 ensures you restore correct hydraulic response and drive control without compromise.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact tolerances for servo piston travel, pressure response, and sealing, ensuring the hydraulic drive system operates as originally engineered
- Direct Drop-In Replacement — engineered to the original form and interface, this servo piston installs directly into compatible BW-series and C 850-series single drum rollers without modification
- Broad Single Drum Roller Coverage — fits BW 211, BW 212, BW 213, BW 214, BW 215, and BW 216 single drum rollers across multiple generations, as well as the C 850 C and C850D, making it a versatile stock item for mixed fleets
- Restores Accurate Drive Response — a worn or failed servo piston causes sluggish, erratic, or unresponsive propulsion control; replacing it with part number 05817652 restores sharp, proportional drive behavior critical to grading and compaction accuracy
- Hydraulic System Integrity — correct servo piston sealing prevents internal hydraulic bypass and pressure loss, protecting downstream pump and motor components from accelerated wear
The servo piston is a precision hydraulic component housed within the variable-displacement pump or drive control circuit of a single drum roller. It responds to operator input by adjusting swashplate angle or valve position, which in turn controls the speed and direction of the hydrostatic drive. When the servo piston wears, develops internal leakage, or seizes, the machine loses the ability to respond accurately to travel commands — resulting in sluggish movement, drift, or complete loss of propulsion. Replacing it promptly with a correctly specified OEM part keeps the hydrostatic system functioning as designed and protects the broader hydraulic circuit from compounding damage.
