The Bomag 05586186 Planetary Housing is a genuine OEM component designed for Bomag BW 145, BW 177, and BW 179 series single drum rollers. Sourced directly from Bomag, this planetary housing matches the original specification exactly, ensuring a correct fit without any adaptation. This part covers an extensive range of single drum roller variants across the BW 145, BW 177, and BW 179 families, including D, DH, PDH, DHC, and PDHC configurations spanning -3, -4, -40, and -50 generation models, as well as the C 825 C single drum roller. When the original housing wears or fails, this genuine OEM replacement restores the drive system to full working order.
Key Features
- Genuine OEM Construction — Manufactured to Bomag's original material and dimensional tolerances for the planetary drive assembly, ensuring the housing properly supports gear loads and bearing interfaces under compaction stress.
- Direct-Fit Replacement — Matches the original housing profile, mounting points, and internal bore geometry so this part drops into place without machining or modification.
- Broad Single Drum Roller Coverage — Fits BW 145, BW 177, and BW 179 single drum rollers across multiple drive configurations and generation variants, including the C 825 C.
- Drive System Integrity — A sound planetary housing keeps the gear set correctly aligned and fully enclosed, maintaining torque transfer efficiency to the drum and preventing premature gear and bearing wear.
- Verified Part Number Fit — Order with confidence using Bomag part number 05586186, confirmed against the BW 145, BW 177, and BW 179 model families to eliminate the risk of ordering an incompatible housing.
The planetary housing is the structural casing that encloses the planetary gear set within the drum drive system. It holds the ring gear, carrier, and associated bearings in precise alignment, allowing the planetary reduction to transfer engine torque to the compaction drum smoothly and efficiently. When the housing cracks, warps, or its internal surfaces wear beyond tolerance, gear misalignment follows — leading to increased noise, loss of drive force at the drum, and accelerated damage to the surrounding drivetrain components.
