The Wacker Neuson Pendulum Joint is a genuine OEM component designed for the RD24-100, RD27-120, RD28-120, and their C, O, and DPF variant Tandem Rollers. As a direct factory replacement, this part carries the same specifications and construction standards as the original unit installed at the time of manufacture. It is compatible across a broad range of RD-series tandem roller configurations, including standard, canopy, operator platform, and DPF emissions-compliant models. Ordering by verified part number ensures you are receiving the correct component for your specific machine build.
Key Features
- Genuine OEM Articulation Integrity — Manufactured by Wacker Neuson to the same tolerances and material specifications as the original, maintaining the precise pivot characteristics this joint was engineered to deliver.
- Direct-Fit Replacement — Engineered to install in the same mounting position as the factory unit, with matching connection geometry across all compatible RD-series roller configurations.
- Broad RD-Series Compatibility — Fits RD24-100 and RD27-120 / RD28-120 Tandem Rollers across standard, canopy (C), open-platform (O), and DPF-compliant variants, covering multiple production generations.
- Smooth Steering and Frame Articulation — A correctly functioning pendulum joint allows the front and rear drum frames to pivot independently, enabling accurate steering response and consistent compaction passes on grade changes and curves.
- Genuine OEM Parts Documentation — Sourced directly through the Wacker Neuson parts network, ensuring traceability and accurate part number verification for service records.
The pendulum joint is the pivoting connection point between the front and rear frame sections of an articulated tandem roller. It allows the two drum assemblies to swing independently of each other, giving the machine its steering capability and enabling it to follow uneven terrain without losing drum contact with the surface. When this joint wears, becomes loose, or fails, the operator will notice imprecise steering, excessive play in the articulation, uneven compaction patterns, or abnormal stress transferred into the frame — all of which compromise both output quality and machine longevity.
