The Wacker Neuson 5100011745 is a genuine OEM O-Ring Seal designed for the RD-series tandem rollers and RC110 single-drum soil compactors. As a direct OEM replacement sourced through the Wacker Neuson parts program, part 5100011745 is manufactured to the same material and dimensional standards as the original seal installed at the factory. This O-Ring Seal fits an extensive range of RD24, RD27, RD28, RD40, and RD45 tandem roller configurations, as well as RC110 ROPS and CAB models — including open drum, combination, DPF, and cab variants across multiple production series. Confirm your model number before ordering to ensure a correct application match.
Key Features
- Correct Compound and Cross-Section: — Genuine OEM formulation ensures the seal material and durometer rating match the original specification for this hydraulic or fluid circuit application.
- Drop-In Seating: — Dimensioned to seat correctly in the original groove without stretching, pinching, or improvised shimming, allowing a straightforward service replacement.
- Broad RD and RC110 Coverage: — Compatible with RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across open drum, combination drum, DPF, ROPS, and CAB variants, plus RC110 ROPS and CAB single-drum compactors.
- Leak Prevention Where It Counts: — A correctly seated O-Ring Seal maintains system pressure and prevents fluid weeping at the joint, keeping hydraulic efficiency and compaction output at their intended levels.
- Fluid Containment and Environmental Compliance: — Maintaining an intact seal prevents hydraulic fluid from escaping to the ground or drum surface, supporting site environmental requirements and machine cleanliness.
An O-Ring Seal creates a pressure-tight barrier between mating components in a hydraulic or fluid circuit, preventing leaks at joints, ports, and fittings. On heavy compaction equipment such as tandem rollers and single-drum soil compactors, where hydraulic systems drive the drums, steering, and vibration mechanisms, a failed or degraded O-Ring can result in fluid loss, pressure drop, and reduced compaction output. Replacing a worn or damaged O-Ring Seal promptly restores the integrity of the sealed joint and prevents secondary damage to surrounding hydraulic components.
