The Multiquip 00422 Drum (33") Small RW-1402/1403 is a genuine OEM replacement drum designed for RAMMAX walk-behind rollers including the RW1403HF, RW1404, RW1404MR, and RW1504HF, as well as select DLW and GAW series light welders. As a direct OEM part sourced through Multiquip's authorized supply chain, 00422 is built to the same specification as the original component — no guesswork on fit or form. This drum is also confirmed compatible with P33/24 series roller configurations, making it a versatile OEM solution across multiple Multiquip equipment families. If you're unsure whether this drum fits your specific serial number range, contact DHS Equipment for verification before ordering.
Key Features
- OEM-Grade Steel Construction — Manufactured to original drum dimensions and material spec, ensuring correct contact area and compaction surface integrity across all listed roller models.
- Direct-Swap Fitment — Engineered to mount to the same drum housing and drive interface as the original, allowing straightforward R&R without custom fitting or machining.
- Broad Roller Compatibility — Confirmed fit for RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), and P33/24 FR/FC/FCR and HHMR-BD configurations.
- Welder Series Fitment — Also listed for DLW300, DLW330X2, DLW400, DLW500 and GAW180 series light welders where this drum assembly is used.
- Sustained Compaction Performance — A worn or cracked drum causes uneven surface contact and inconsistent compaction; replacing with the correct OEM drum restores full-width, uniform ground pressure.
The compaction drum is the primary ground-contact component on a walk-behind vibratory roller. It transfers the combined weight and vibratory force of the machine directly to the compaction surface, consolidating soil, gravel, or asphalt uniformly across the drum's full width. When a drum becomes cracked, out-of-round, or structurally compromised, it produces uneven compaction patterns, accelerates bearing wear, and can create safety concerns during operation. Replacing the drum with a correct OEM part restores the machine's designed compaction output and protects adjacent drivetrain components from the stress caused by an imbalanced or damaged drum.
