This pinion fits the BW 55 E walk-behind roller, making it the correct choice when restoring drive function on this machine.
Key Features
- Genuine OEM Gear Geometry — machined to the original tooth profile and hardness spec, ensuring proper mesh and load transfer within the drivetrain
- Direct Replacement — engineered to match the original mounting interface and gear dimensions of the BW 55 E, so this pinion installs without modification
- Confirmed Fitment — verified for the Bomag BW 55 E walk-behind roller under part number 05900017
- Restored Drive Efficiency — a worn or damaged pinion causes slippage, vibration, and loss of propulsion; replacing it restores smooth, consistent power delivery to the drum
- Backed by Bomag OEM Standards — genuine Bomag parts are held to the same quality controls as production components, giving you confidence in long-term drivetrain integrity
A pinion is a small-diameter gear that meshes with a larger mating gear to transmit rotational force through a drivetrain or final drive assembly. In a walk-behind roller like the BW 55 E, the pinion plays a direct role in translating engine power into drum movement, keeping the machine moving and compacting effectively. When a pinion wears down or loses teeth, it disrupts the gear mesh, resulting in rough operation, loss of drive, and accelerated wear on surrounding components — making timely replacement essential to keeping the machine productive.
