The Wacker Neuson 5200012109 Disc is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. As a direct OEM replacement, this disc is produced to the same specifications as the original part installed at the factory, ensuring a proper fit within the roller's mechanical assembly. Confirmed fitment spans multiple configurations of the RD7 family, making 5200012109 a reliable choice when servicing these compact tandem rollers.
Key Features
- Genuine OEM Construction — Manufactured to original Wacker Neuson specifications, ensuring correct material grade and dimensional accuracy for this disc application.
- Direct-Fit Replacement — Engineered to install in the same position and orientation as the original, with no rework needed to the surrounding assembly.
- Broad RD7 Series Coverage — Fits RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, including both standard and walk-behind configurations across multiple machine numbers.
- Maintains Drive or Braking Integrity — A correctly fitted disc supports consistent mechanical engagement within the roller's drivetrain or braking system, contributing to smooth, controlled operation on asphalt and soil compaction passes.
- Verified Part Number — Sourced directly from Wacker Neuson, so the part number 5200012109 matches the OEM parts record for your specific RD7 model.
A disc within a walk-behind tandem roller like the RD7 series typically functions as a precision-machined component within the drivetrain, clutch, or braking assembly, transmitting or interrupting rotational force between moving parts. When this disc wears, warps, or becomes damaged, the roller may exhibit inconsistent forward or reverse travel, reduced braking response, or vibration irregularities that compromise compaction quality. Replacing the disc with a correct OEM part restores the mechanical relationship between connected components and helps the machine perform as designed across asphalt finishing and soil compaction applications.
