The Bomag 05726973 Pinion is a genuine OEM component designed for BW 120 AD tandem rollers and BW 213 D-3 and BW 213 DH-3 single drum rollers. Sourced directly from Bomag, this pinion matches the original part's tooth profile, material grade, and dimensional tolerances — so it meshes correctly with its mating gear without adjustment. This is the correct replacement when drive efficiency drops or worn gear teeth cause noise, vibration, or loss of power transfer in the drivetrain.
Key Features
- OEM Tooth Geometry — manufactured to Bomag's original tooth profile and hardness spec, ensuring correct gear mesh and load distribution from the first hour of use
- Drop-In Drivetrain Replacement — matches the original shaft interface and gear count, fitting directly into the existing drive assembly on compatible machines
- Broad Bomag Coverage — fits the BW 120 AD tandem roller and BW 213 D-3 and BW 213 DH-3 single drum rollers, covering multiple machine configurations with a single part number
- Sustained Power Transfer — a correctly spec'd pinion maintains full torque delivery through the drivetrain, supporting consistent compaction force and smooth drum operation across the worksite
- Wear-Resistant Construction — built to withstand the continuous rotational load and high-torque demands typical of vibratory roller drivetrains, helping the gear set stay in service longer between rebuilds
A pinion is a small-diameter drive gear that meshes with a larger ring or spur gear to transfer rotational force through a machine's drivetrain or final drive assembly. In a roller, the pinion plays a key role in converting engine output into drum rotation, and any wear or damage to its teeth reduces efficiency, introduces play, and can accelerate wear on the mating gear. Replacing a worn pinion with a correctly dimensioned OEM part restores clean gear engagement, prevents secondary damage to surrounding components, and brings drivetrain performance back to its original spec.
