Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original design tolerances, ensuring correct pressure routing, flow control, and port alignment critical to a hydraulic control block's performance
- Direct Drop-In Replacement — engineered to match the original mounting configuration and port geometry, allowing this control block to install directly in place of the factory unit
- Confirmed Tandem Roller Fitment — verified for the BW 138 AD and BW 135 AD tandem rollers, so you can order with confidence that this is the right part for your machine
- Hydraulic System Integrity — a correctly functioning control block maintains proper fluid direction and pressure regulation across the drive and vibration circuits, keeping compaction output consistent and predictable
- Authentic Bomag Part Number — part number 05877058 matches Bomag's own parts catalog, eliminating guesswork and reducing the risk of ordering an incompatible component
A control block is a machined hydraulic manifold that directs pressurized fluid to the correct circuits within the machine — in a tandem roller like the BW 138 AD and BW 135 AD, this means managing flow to the drive, steering, and vibratory drum systems from a centralized valve body. When the control block is worn, cracked, or internally bypassing, the machine may exhibit sluggish response, uneven drum drive, or loss of vibration — all of which directly affect compaction quality and cycle times. Replacing a failed control block with a genuine Bomag unit restores correct hydraulic command and gets the roller back to full operating specification.
