Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original tolerances, ensuring correct valve porting, flow rates, and pressure ratings specific to this control block application
- Direct-Fit Installation — matches the original mounting interface and hydraulic port configuration, allowing technicians to swap in this control block without machining or custom fittings
- Broad Tandem Roller Coverage — fits BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ADH, BW 131 ACW-2, BW 135 AD, BW 138 AC, BW 138 AD, and BW 138-AD tandem rollers, covering a wide range of the Bomag tandem roller lineup
- Restored Hydraulic Control Response — a worn or failed control block causes sluggish, erratic, or unresponsive drive and vibration control; this replacement restores sharp, predictable hydraulic response across all operator inputs
- Verified Part Number Integrity — order by Bomag part number 05878159 with confidence; DHS Equipment supplies authentic Bomag OEM parts with accurate fitment documentation
The control block is a precision hydraulic valve assembly that directs and regulates pressurized fluid flow to the drive, steering, and vibration circuits of the tandem roller. It acts as the central routing hub between the hydraulic pump and the working components of the machine, controlling speed, direction, and compaction force in response to operator commands. When a control block begins to leak internally, sticks, or fails outright, the machine loses responsive control over its drive or vibration system — resulting in inconsistent compaction output, unpredictable handling, and potential damage to downstream hydraulic components.
