The Bomag 05585903 Bevel Gear and Pinion is a genuine OEM component designed for Bomag BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 D-3, BW 177 DH-3, BW 178 D-3 single drum rollers, the C 825 C single drum roller, and the MPH 121 recycler/stabilizer. Sourced directly from Bomag, this Bevel Gear and Pinion meets the exact tolerances and material specifications of the original drivetrain component. With verified fitment across this range of machines, part number 05585903 is a direct, confidence-inspiring replacement for worn or damaged drive gear sets.
Key Features
- Genuine OEM Gear Precision — machined to Bomag's exact tooth profile and hardness specifications, ensuring smooth, low-wear meshing under the high torque loads typical of single drum roller drivetrains
- Drop-In Drive Replacement — engineered to match the original mounting dimensions and gear ratio, so this bevel gear and pinion seats correctly without modification to the differential or final drive housing
- Broad Confirmed Fitment — compatible with BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 D-3, BW 177 DH-3, BW 177 DH 3, BW 178 D-3, C 825 C single drum rollers, and the MPH 121 recycler/stabilizer
- Drivetrain Integrity Restored — a worn or broken bevel gear set causes loss of drive force, uneven drum rotation, and audible gear noise; replacing with this genuine set restores full torque transfer and smooth operation
- Long-Term Wear Resistance — manufactured from the same high-strength alloy steel as the original, ensuring the gear faces and pinion teeth hold up under continuous compaction and stabilization cycles
The bevel gear and pinion is a paired drive component that transfers rotational power from the driveshaft to the drum or axle at a 90-degree angle, allowing the machine's engine output to be redirected to the correct drive axis. The two gears must mesh with precise tooth contact — if either wears, chips, or loses its geometry, the result is lost drive efficiency, increased heat buildup, and eventual drivetrain failure. Replacing both the bevel gear and pinion together as a matched set, as supplied with part number 05585903, ensures correct contact patterns and balanced load sharing from the first revolution.
