The Wacker Neuson Set of Seals is a genuine OEM set of seals designed for the RD18, RD40, and RD45 series tandem rollers. Sourced directly from Wacker Neuson, this set meets the original engineering specifications for the models it serves, covering a broad range of configurations including standard, C, O, and.3 variants across both US and international builds. If you're servicing a roller in the RD18-80, RD18-100, RD40-130, or RD45-140 family, part number is the correct OEM replacement. Installing the right seal set keeps hydraulic and mechanical systems properly contained, helping your roller stay productive through demanding compaction work.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compression and material specifications, ensuring proper sealing performance under the pressure and heat cycles typical of tandem roller operation.
- Direct Drop-In Replacement — Engineered to install in the same positions as the original seals, with no reworking of housings or mating surfaces required.
- Broad RD Series Coverage — Fits a wide range of RD18, RD40, and RD45 tandem roller configurations, including standard, C-cab, open-ROPS, and .3-generation models across US and international variants.
- Prevents Fluid Loss and Contamination — Worn or degraded seals allow hydraulic fluid to escape and allow contaminants to enter, leading to accelerated internal wear and loss of compaction force. A fresh seal set restores the integrity of the system.
- Genuine Wacker Neuson OEM Part — Part number 5100012797 is an authentic Wacker Neuson component, not a generic substitute, giving you confidence in fitment accuracy across all listed model numbers.
Seals in a tandem roller serve as the critical barriers that keep hydraulic fluid contained within the drum drive and vibration systems while blocking dirt, water, and debris from entering sensitive internal components. When seals degrade — through heat cycling, age, or contamination — fluid leaks begin, pressure drops, and internal surfaces are exposed to wear that can escalate quickly into costly component failure. Replacing a worn set of seals at the first sign of leakage is one of the most cost-effective forms of preventive maintenance you can perform on a compaction roller.
