The Wacker Neuson Stay Bar is a genuine OEM component designed for the RD18, RD24, RD28, RD40, and RD45 tandem roller series, as well as the RC110 ROPS and RC110 CAB models. Sourced directly from Wacker Neuson, this is the same stay bar installed at the factory — not an approximation. Fitment spans a wide range of configurations across the RD series, including standard, cab, open-ROPS, DPF, and electric variants, making this a broadly compatible OEM part for Wacker Neuson tandem roller fleets.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the stay bar maintains its load-bearing and alignment function without flex or fatigue under compaction stress.
- Direct Drop-In Replacement — Matches original mounting points and hardware interfaces on covered RD and RC series models, allowing straightforward installation without modification to brackets or fastener locations.
- Broad RD and RC Series Coverage — Fits RD18, RD24, RD28, RD40, and RD45 tandem rollers across standard, cab, open-ROPS, DPF, and electric configurations, plus RC110 ROPS and RC110 CAB models.
- Frame Stability Under Load — A correctly fitted stay bar keeps critical structural members in alignment during operation; a worn or damaged bar can allow unwanted movement that accelerates wear on surrounding components.
- Verified OEM Part Number — Part number 5100067838 is the exact Wacker Neuson reference for this application, eliminating guesswork when cross-referencing against machine serial numbers or service documentation.
A stay bar is a structural bracing component that holds two points of a machine's frame or assembly in a fixed positional relationship. On tandem rollers, it resists the dynamic forces generated during compaction passes, preventing lateral flex or misalignment between major structural sections. When a stay bar becomes bent, cracked, or loses its mounting integrity, the resulting movement can place undue stress on adjacent frame members, drum assemblies, or articulation joints — leading to accelerated wear and potential service issues if left unaddressed.
