The Bomag 58040129 Intermediate Ring is a genuine OEM component designed for BW 177 series single drum rollers, including BW 177 D, BW 177 DH, and BW 177 PDH variants across the -3, -4, -40, and -50 generations. Sourced directly from Bomag, this intermediate ring delivers an exact fit with no guesswork on compatibility. It is the correct replacement for machines running across the full BW 177 lineup, covering drum drive, padfoot drum, and compaction-monitoring configurations. When it is time to restore your roller to proper operating condition, part number 58040129 is the confirmed OEM solution.
Key Features
- Genuine OEM Fitment — manufactured to Bomag's exact dimensional tolerances, ensuring this intermediate ring seats and seals correctly within the drum assembly without rework or shimming
- Broad BW 177 Series Coverage — fits BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 177 D-4, BW 177 DH-4, BW 177 PDH-4, BW 177 DHC-4, BW 177 PDHC-4, BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, and BW 177 PDH-50 single drum rollers
- Structural Integrity Under Load — provides the correct load-bearing transition between drum components, maintaining alignment and even force distribution during compaction cycles
- Direct OEM Replacement — part number 58040129 cross-references directly to the original Bomag part, so there is no need to verify alternate numbers or measure for fitment
- Protects Adjacent Components — a worn or failed intermediate ring allows unwanted movement between drum sections, accelerating wear on seals, bearings, and housing surfaces
The intermediate ring is a precision-fit spacer component positioned between mating sections of the drum or drive assembly on BW 177 single drum rollers. It maintains correct spacing, alignment, and load transfer between adjacent parts, preventing metal-to-metal contact and keeping the drum assembly running true under the high-cycle vibration loads these rollers generate. When this ring wears, cracks, or shifts out of position, it can allow misalignment that puts stress on surrounding seals and bearings — leading to more extensive repairs if not addressed promptly.
