The Bomag 05559641 Angular Reduction is a genuine OEM component designed for a wide range of Bomag tandem rollers and recycler/stabilizers, including the BW 120 AD, BW 174 AD, BW 184 AD, MPH 600, and RS 650. As a direct factory replacement, this angular reduction is sourced to the same specifications as the original, ensuring a proper fit without modification. It is compatible across an extensive lineup of BW-series tandem rollers spanning multiple generations, from the BW 80 ADS and BW 90 AC-2 through the BW 184 AD-2 AM, as well as MPH 600 and RS 650 recycler/stabilizers. When you need a dependable, OEM-correct part to restore your machine to full working order, this angular reduction is the right choice.
Key Features
- Genuine OEM Gearing Accuracy — manufactured to Bomag's original torque and angular specifications, ensuring correct power transfer through the drivetrain without improvised substitution
- Drop-In Replacement — engineered to match the original mounting configuration, allowing installation directly into the application without rework or adapter fittings
- Broad Tandem Roller Coverage — fits an extensive range of Bomag tandem rollers including BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, BW 138, BW 151, BW 161, BW 170, BW 174, BW 180, and BW 184 series, plus MPH 600 and RS 650 recycler/stabilizers
- Drivetrain Integrity — a correctly functioning angular reduction transmits power at the proper angle and ratio, keeping drum drive and propulsion operating smoothly; a worn unit causes vibration, gear noise, and loss of traction or drum rotation
- Multi-Generation Compatibility — covers AC, AD, ACW, ACH, ADH, AP, and AM variants across multiple production generations, making this a versatile stock item for fleets running mixed BW-series tandem rollers
An angular reduction — sometimes called an angle gearbox or bevel gearbox — redirects rotational power from a drivetrain shaft to a different axis, typically changing the direction of torque by 90 degrees. In Bomag tandem rollers and recycler/stabilizers, this component plays a key role in transmitting engine or motor power to the drum drive or travel system at the correct angle and gear ratio. When the angular reduction wears or fails, the machine may exhibit unusual noise from the gearbox, reduced drive efficiency, or complete loss of motion in the affected system, making timely replacement essential to keeping the roller productive.
