The Multiquip 508434 Backing Plate is a genuine OEM component designed for AR13D, AR13H, AR13HA, AR13HAR, and AR13HC ride-on asphalt rollers. Sourced directly from Multiquip, this part matches the original specification exactly, ensuring a correct, trouble-free installation. If your roller is showing wear or damage at the backing plate, replacing it with the correct OEM part keeps the drum assembly operating as intended. DHS Equipment stocks this part to get your roller back on the mat without delay.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional spec, so the plate seats and bears load the same way the original did from day one.
- Direct Drop-In Installation — Engineered to match the original mounting pattern and profile on AR-series roller drum assemblies, requiring no modification to surrounding hardware.
- Broad AR-Series Fitment — Compatible with AR13D, AR13H, AR13HA, AR13HAR, and AR13HC ride-on asphalt rollers, covering diesel and Honda-powered variants across the AR13 family.
- Structural Support for the Drum Assembly — A correctly fitted backing plate maintains proper drum alignment and load distribution, preventing premature wear to adjacent components.
- Verified Part Number — Confirmed as Multiquip part 508434; always match this number against your machine's parts manual before ordering to ensure correct application.
The backing plate serves as a structural support surface within the roller's drum or brake assembly, providing a stable foundation against which mating components bear and transfer force. Without a sound backing plate, surrounding parts lose their correct seating, leading to uneven wear, vibration, or loss of compaction consistency across the drum. Replacing a worn or cracked backing plate restores proper load distribution and protects the integrity of the broader assembly.
