The Bomag 05561278 Control Box with Lever is a genuine OEM component designed for the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD-4, BW 125 AC-4, and BW 125 AD-4 tandem rollers. Sourced directly from Bomag, this control box with lever matches the original specification for a straight, hassle-free installation. It is the correct replacement when the existing control box or integrated lever shows wear, damage, or loss of operator response — restoring full control functionality to your machine.
Key Features
- Genuine OEM Precision — manufactured by Bomag to the exact tolerances and switching characteristics required for proper operator control response on tandem rollers
- Direct Drop-In Replacement — matches the original mounting configuration and connector layout, fitting the existing housing without rework or adaptation
- Broad Tandem Roller Coverage — fits BW 100 AC-4, BW 100 AD-4, BW 120 AC-4, BW 120 AD-4, BW 125 AC-4, and BW 125 AD-4 tandem rollers, covering multiple variants across the BW 100 and BW 120 series
- Operator Control Restored — a worn or malfunctioning control box with lever can cause erratic or unresponsive machine behavior; this part brings input accuracy back to spec so the operator retains confident, precise command of the roller
- Electrical Integrity — as a genuine OEM part, the lever and box assembly delivers the correct electrical output and contact ratings, reducing the risk of signal faults or premature failure under continuous operation
The control box with lever serves as the primary operator interface for directing machine functions on Bomag tandem rollers. It translates the operator's physical lever inputs into electrical signals that govern drive, vibration, and directional control systems. When the control box or its lever degrades — through contact wear, moisture ingress, or mechanical fatigue — operators may experience sluggish response, intermittent signal loss, or complete loss of a control function, all of which affect compaction consistency and safe machine operation. Replacing this assembly with an exact OEM unit ensures the signal path is fully restored and the lever action returns to its original feel and accuracy.
