The Bomag 05585971 Differential Housing is a genuine OEM component designed for BW 145, BW 177, and BW 179 series single drum rollers. Sourced directly from Bomag, this housing meets the exact dimensional and material standards of the original part, ensuring a correct, trouble-free installation. It provides fitment coverage across a wide range of generation variants including D-3, DH-3, PDH-3, D-4, DH-4, PDH-4, DHC-4, PDHC-4, D-40, DH-40, PDH-40, D-50, DH-50, and PDH-50 configurations, as well as the C 825 C single drum roller. When drivetrain integrity is critical to keeping your compaction passes on schedule, replacing a worn or damaged differential housing with genuine part number 05585971 is the correct call.
Key Features
- Genuine OEM Casting Quality — manufactured to Bomag's original material and dimensional specifications, so the housing walls, bearing bores, and mounting faces align exactly as the drivetrain demands
- Direct-Fit Installation — bolt pattern, bore dimensions, and seal seat geometry match the original, allowing straightforward installation without machining or shimming
- Broad BW-Series Coverage — fits BW 145, BW 177, and BW 179 single drum rollers across D-3 through D-50 generation variants, including DHC-4, PDHC-4, and USA-spec models, as well as the C 825 C single drum roller
- Restored Drivetrain Function — a structurally sound differential housing maintains correct gear alignment and bearing support, preserving smooth, controlled power delivery to the drum drive axle
- Long-Term Structural Integrity — the OEM housing resists the torsional loads and vibration inherent to heavy soil compaction work, reducing the risk of premature bearing failure or gear misalignment
The differential housing is the structural enclosure that contains the differential gear set, side gears, and bearings responsible for splitting and distributing drive torque between the machine's drive wheels or axle shafts. It keeps all rotating components in precise alignment under the heavy loads generated during soil compaction passes. When the housing cracks, warps, or suffers bearing bore wear, gear mesh is compromised — leading to abnormal noise, vibration, uneven power delivery, and ultimately drivetrain seizure if left unaddressed. Replacing a damaged housing with genuine Bomag part number 05585971 restores the structural foundation the entire differential assembly depends on.
