Key Features
- Genuine OEM Precision — manufactured to Bomag's exact tolerances for proper mesh, load distribution, and wear resistance specific to these drivetrain applications
- Direct-Fit Replacement — matches the original gear geometry and mounting interface, allowing straightforward installation without modification
- Broad Fitment Coverage — compatible with BW 177 and BW 213 series single drum rollers, BW 184 AD and BW 180 AD tandem rollers, and the C 850 C single drum roller
- Drivetrain Integrity — a worn or damaged gear causes power loss, rough operation, and accelerated wear on mating components; replacing it promptly restores smooth, efficient power transfer
A gear is a fundamental drivetrain component responsible for transmitting rotational force between shafts, controlling speed reduction or increase, and ensuring power reaches the drum or drive system efficiently. In compaction equipment like single drum and tandem rollers, gears must handle sustained load cycles under demanding site conditions. When a gear wears excessively or fails, it can cause slipping, noise, vibration, or a complete loss of drive — all of which compromise compaction output and can lead to more extensive drivetrain damage if left unaddressed. Replacing the gear with a genuine OEM part restores proper mesh and load transfer across the full drivetrain.
