The Wacker Neuson is a genuine OEM rear frame part designed for the RD40-130 and RD45-140 tandem roller series, including standard, C, O, DPF, and US-spec variants. As a direct Wacker Neuson OEM component, this part is built to the exact tolerances and material specifications of the original, ensuring a correct, no-compromise fit within the roller's frame assembly. Fitment covers an extensive range of RD40-130 and RD45-140 configurations across multiple production variants, making this a versatile stocking part for fleets running multiple machine specs. Verify your machine's model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Structural Integrity — Manufactured to Wacker Neuson's original dimensional and material specifications, delivering the load-bearing strength expected of a genuine frame component.
- Direct Bolt-In Replacement — Matches original mounting points and attachment geometry on RD40-130 and RD45-140 tandem rollers, so the part installs into the existing frame structure without alteration.
- Broad Series Fitment — Compatible across RD40-130 and RD45-140 variants including standard, C, O, DPF, and US-spec configurations, spanning multiple production generations.
- Maintains Frame Rigidity — A sound rear frame part keeps the roller's drivetrain, drum mounts, and operator platform properly aligned; a cracked or deformed rear frame can cause misalignment, vibration, and accelerated wear across connected components.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100012730 carries the assurance of an authorized OEM component, not a pattern copy.
The rear frame part forms the backbone of the rear section of a tandem roller, connecting the rear drum assembly, engine or drivetrain mounts, and articulation joint to the rest of the machine. It bears the structural loads generated during compaction passes and transfers forces evenly across the chassis. When a rear frame component is cracked, bent, or otherwise compromised, it can cause misalignment between the drum and the machine's centerline, uneven compaction, excessive vibration, and potential damage to surrounding assemblies — making timely replacement critical to keeping the roller performing correctly on site.
