The Wacker Neuson 5100011809 is a genuine OEM Flange designed for the RD40-130 and RD45-140 series tandem rollers, including standard, combination, offset drum, and DPF-equipped configurations. As a factory-sourced component, part 5100011809 is manufactured to the exact tolerances and material specifications required for proper function within these machines. This flange fits an extensive range of RD40-130 and RD45-140 variants, covering US-market models, open-drum (o), combination (c), and Stage IIIA (.3) and DPF emissions configurations. Confirm your model number before ordering to ensure a direct match.
Key Features
- Exact OEM Dimensional Spec — Manufactured to precise bore and bolt-pattern tolerances required for proper seating and load transfer on RD40-130 and RD45-140 drivetrain assemblies.
- Broad RD-Series Coverage — Fits the full RD40-130 and RD45-140 family, including standard, combination (c), offset (o), Stage IIIA (.3), DPF, and US-market variants.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number (5100011809) used in the original equipment build — no substitution or adaptation needed.
- Preserves Drivetrain Integrity — A correctly fitted flange maintains proper alignment and torque transfer; a worn or mismatched flange can cause vibration, premature bearing wear, and loss of drive performance on compaction passes.
- Multi-Configuration Fitment — Compatible across a wide production run of RD40-130 and RD45-140 machines, making it a reliable stock part for fleets running multiple roller configurations.
A flange is a mechanical connection component that joins rotating or stationary assemblies within the roller's drivetrain or drum system, providing a secure, aligned interface that transfers load and rotational force between mating components. On a tandem roller like the RD40-130 and RD45-140, maintaining the correct flange condition is critical to smooth drum operation and consistent compaction performance across asphalt and soil surfaces. When a flange becomes worn, cracked, or incorrectly seated, it can introduce vibration, misalignment, and accelerated wear on surrounding drivetrain components, making timely replacement essential.
