The Bomag 05585889 Planetary Housing is a genuine OEM component designed for Bomag single drum rollers. Sourced directly from Bomag, this planetary housing delivers an exact match to the original unit — correct geometry, correct material, correct fit. This part is confirmed to fit the BW 142 D-2, BW 172 D-2, BW 177 D-3, BW 178 D-3, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 DH-3, and C 825 C single drum rollers, among others in the covered range. When a drive system component needs to be replaced, specifying genuine OEM gives you the assurance that the housing will mate correctly with all internal planetary components without rework or shimming.
Key Features
- Genuine OEM Precision — Manufactured to Bomag's original tolerances, ensuring the planetary gear set seats and loads correctly within the final drive assembly.
- Direct Drop-In Replacement — Matches the original housing profile and mounting interface exactly, so installation proceeds without machining or modification.

- Drive System Integrity — A sound planetary housing keeps gear alignment consistent under load, preventing premature bearing and gear wear across the full drive cycle.
- Verified Part Number — Order with confidence using Bomag part number 05585889, matched directly to the original Bomag catalog for the covered models.
The planetary housing is the structural shell that encloses the planetary gear set in the final drive of a single drum roller. It holds the ring gear, planet gears, and carrier in precise alignment, transferring torque from the drive motor to the drum or wheel while withstanding the high radial and axial loads generated during compaction passes. When the housing cracks, wears out of round, or its bearing bores become damaged, the gear set loses alignment — leading to accelerated wear on the planet gears and bearings, oil leaks at the housing seals, and ultimately final drive failure. Replacing a damaged housing promptly with a genuine OEM unit restores the correct load path and protects the surrounding drivetrain components.
