The Bomag 05586420 Differential Housing is a genuine OEM component designed for Bomag single drum rollers across the BW 145, BW 177, BW 211, BW 212, BW 213, and BW 215 series. Sourced directly from Bomag, this housing meets the original design tolerances that keep your drivetrain operating as intended. Compatible models include the BW 211 D-5, BW 213 D-5, BW 177 D-5, BW 177 DH-5, BW 145 D-5, BW 212 D-40, and BW 213 PD-40, among many others in the -4, -40, -50, and -5 generation lines. When you need an exact-fit replacement, part number 05586420 is the correct choice for this application.
Key Features
- Genuine OEM Dimensional Accuracy — Cast and machined to Bomag's original housing specifications, ensuring correct gear mesh, bearing seat alignment, and oil retention that aftermarket castings may not replicate.
- Direct Bolt-In Replacement — Engineered to match the original mounting pattern and interface dimensions of the differential assembly, so installation follows the standard service procedure without rework.
- Broad Single Drum Roller Coverage — Fits an extensive range of Bomag single drum rollers including BW 145, BW 177, BW 211, BW 212, BW 213, and BW 215 variants across the D, PD, DH, and PDH configurations in -4, -40, -50, and -5 generations.
- Drivetrain Integrity Restored — A damaged or cracked differential housing allows lubricant loss and contaminant ingestion, leading to rapid gear and bearing wear; replacing it with this housing returns the drivetrain to sealed, load-bearing condition.
- Verified Part Number — Ordering by Bomag part number 05586420 confirms you receive the correct casting for your machine generation — critical given the number of BW-series variants that share similar but non-interchangeable housings.
The differential housing is the structural casing that encloses the differential gear set, allowing the drive axle to distribute torque between wheels while permitting speed differences during turns. It supports the ring and pinion gears, houses the differential carrier bearings, and retains the gear oil that lubricates the entire assembly. When the housing cracks, warps, or develops a compromised seating surface, oil leaks out, contamination enters, and gear and bearing wear accelerates rapidly — ultimately leading to drivetrain failure and costly downtime on compaction work.
