The Bomag 05878112 Control Block is a genuine OEM component designed for BW 161 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers. Sourced directly from Bomag, this control block meets the same specifications as the original unit installed at the factory, ensuring hydraulic system integrity is fully restored. If you're servicing any of these tandem roller models, part number 05878112 is the correct direct replacement to specify.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact tolerances, ensuring correct flow rates, pressure ratings, and porting geometry specific to this control block application
- Direct-Mount Replacement — engineered to match the original mounting interface and port configuration, allowing straightforward installation without modification to hydraulic lines or fittings
- Confirmed Tandem Roller Fitment — verified for the BW 161 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers, so you can order with confidence knowing this is the correct part for your machine
- Restores Full Hydraulic Control — a properly functioning control block maintains accurate distribution of hydraulic flow to the drum drive and steering circuits, keeping the roller responsive and consistent across the pass
- Prevents Uncontrolled Pressure Loss — a worn or failed control block can cause erratic drum behavior, loss of drive response, or hydraulic drift; replacing it with a genuine unit returns the system to stable, predictable operation
The control block is a central hydraulic valve manifold that directs pressurized fluid from the pump to the various working circuits of the roller — including drum drive, vibration, and steering functions. It regulates flow and pressure to each circuit according to operator input, acting as the hydraulic nervous system of the machine. When a control block begins to leak internally or fails to shift correctly, operators will notice sluggish response, uneven drum speed, or a complete loss of drive — all of which halt productive compaction work until the component is replaced.
