The Bomag 05878181 Control Block is a genuine OEM component designed for Bomag tandem rollers across the BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series. Sourced directly from Bomag, this control block meets the exact specifications of the original part it replaces, ensuring correct hydraulic circuit management for your machine. Confirmed fitment covers models including the BW 100 AD-4, BW 100 AC-4, BW 115 AD-3, BW 115 AC-3, BW 115 AC-5, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 131 AD-3, BW 131 ACW-3, BW 131 AD-5, BW 131 ACW-5, BW 135 AD, BW 138 AD, BW 138 AC, and BW 138-AD tandem rollers. Using the correct OEM part number 05878181 ensures you are installing a component built to the same tolerances as the unit that left the factory floor.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact internal porting and pressure specifications, ensuring correct flow routing within the hydraulic circuit of your tandem roller
- Direct Drop-In Replacement — engineered to match the original mounting interface and port configuration, allowing installation without custom adapters or machining
- Broad Tandem Roller Coverage — fits BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series tandem rollers, including AC, AD, and ACW variants across multiple generations
- Protects Hydraulic System Integrity — a correctly functioning control block maintains consistent pressure distribution across the drum drive circuit; a failing unit can cause uneven drum response, sluggish travel, or loss of compaction force
- Hydraulic Safety Compliance — proper control block function is critical for predictable machine response and operator control; using a genuine OEM part ensures the hydraulic system behaves as designed under working load
The control block is a hydraulic manifold component that directs and regulates pressurized fluid to the correct circuits within the roller's drive and compaction system. It acts as a distribution hub, routing flow to drum motors, travel circuits, or auxiliary functions depending on operator input. When a control block wears, cracks, or develops internal leakage, the machine may exhibit erratic drum behavior, loss of drive response, or reduced compaction performance — making timely replacement essential to keeping the roller operating as intended.
