The Bomag 05817188 Valve Plate is a genuine OEM component designed for Bomag BW 135 AD tandem rollers, BW 177-series single drum rollers, and BW 100, BW 120, and BW 177 tandem and single drum roller variants. Sourced directly from Bomag, this valve plate is manufactured to the exact tolerances required by the hydraulic system it serves. Confirmed fitment spans the BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, BW 177 PDH-50, BW 100 AD-4, BW 100 AC-4, BW 120 AD-3, BW 120 AD-4, BW 120 AC-4, and BW 135 AD, among other covered models. When hydraulic performance matters, installing the correct OEM part number 05817188 ensures the system operates as Bomag intended.
Key Features
- OEM Hydraulic Precision — manufactured to Bomag's exact port geometry and surface-finish tolerances, ensuring correct flow control and pressure regulation within the hydraulic pump or motor assembly
- Direct-Fit Replacement — matches the original mounting configuration and port layout, dropping in without machining or adaptation
- Broad Roller Coverage — fits BW 135 AD tandem rollers, BW 177-series single drum rollers (D-3 through D-50 generations), and BW 100 and BW 120 tandem roller variants, including USA-spec models
- Consistent Hydraulic Output — a worn or damaged valve plate causes internal bypass, loss of drive pressure, and uneven drum compaction; this genuine replacement restores full system efficiency
- Genuine Bomag OEM Quality — supplied as an authentic Bomag part, built from materials rated for the operating pressures and duty cycles of Bomag compaction rollers
The valve plate is a critical internal component of a hydraulic piston pump or motor, sitting between the rotating cylinder block and the pump housing. Its precisely machined kidney-shaped ports control the timing and direction of hydraulic fluid flow as the pistons reciprocate, directly governing the pressure and volume delivered to the drive or vibration circuit. When the valve plate wears or becomes scored, internal leakage increases, hydraulic pressure drops, and the roller loses drive power or vibratory force — making prompt replacement essential to restoring full compaction performance.
