The Wacker Neuson Shaft Seal is a genuine OEM Shaft Seal designed for RD18-80, RD18-100, RD18-100 C, RC50, and RC50p series tandem rollers and single drum soil compactors. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional standards of the original component installed at the factory. It covers an extensive range of configurations across the RD18 and RC50 families, including DPF CAB and DPF ROPS variants. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and compression specifications, delivering the same lip geometry and sealing force as the part it replaces.
- Drop-In Installation — Matches the original bore diameter and shaft interface exactly, seating into position without machining or adapting the housing.
- Broad Compactor Compatibility — Fits multiple variants across the RD18-80, RD18-100, RD18-100 C, RC50, and RC50p series, including US, SE, and DPF-equipped models.
- Leak Prevention Where It Counts — A properly seated shaft seal keeps lubricant contained and contaminants out of the drivetrain; a worn or failed seal leads to lubricant loss, accelerated bearing wear, and potential drivetrain damage.
- Genuine Wacker Neuson Part — Carries the full Wacker Neuson OEM designation, giving you direct traceability to the original part specification for this seal application.
A shaft seal is a precision ring fitted around a rotating shaft where it exits a housing, such as a gearbox, drum drive, or hydraulic motor. Its job is to retain lubricating oil or grease on the inside while blocking dirt, water, and debris from entering on the outside. When a shaft seal wears out or becomes brittle, it loses its ability to maintain that barrier — resulting in oil seeping past the lip, contamination entering the assembly, and premature wear of the bearings or gears it was protecting. Replacing a failing shaft seal promptly is one of the most cost-effective ways to protect the surrounding drivetrain components in a compaction machine.
