The Wacker Neuson Shaft Seal is a genuine OEM shaft seal designed for the RD24-100, RD27-120, RD28-120, and RC70 series compactors, including tandem roller and single drum soil compactor configurations. As a direct OEM replacement, this seal is sourced from Wacker Neuson and built to the same material and dimensional standards as the original part. It covers an extensive range of configurations across the RD and RC series, including C, O, DPF, and US variants, as well as CAB and ROPS-equipped RC70 and RC70p models. When it comes to keeping drivetrain and hydraulic interfaces properly sealed, using the correct OEM-specified part is the most straightforward path to a lasting repair.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and compression specifications, ensuring proper sealing contact against the shaft surface without distortion or premature wear.
- Drop-In Installation — Matches the original seat dimensions exactly, seating into the same bore and against the same shoulder as the factory-installed seal for a straightforward swap.
- Broad Series Coverage — Fits RD24-100, RD27-120, RD28-120, and RC70 series machines across standard, C, O, DPF, US, CAB, and ROPS variants — one part number covers a wide range of compactor configurations.
- Leak Prevention at the Source — A correctly functioning shaft seal keeps fluid contained at the shaft interface; a worn or cracked seal allows oil or hydraulic fluid to escape, leading to contamination and accelerated component wear.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5100011878, giving you full confidence in origin, traceability, and fitment accuracy.
A shaft seal is a ring-shaped sealing component fitted around a rotating shaft to prevent oil, grease, or hydraulic fluid from escaping the housing at the point where the shaft exits. In compaction equipment like the RD and RC series rollers, shaft seals are found at drivetrain, drum drive, and hydraulic motor interfaces where rotating assemblies pass through stationary housings. When a shaft seal fails — typically through hardening, cracking, or lip wear — fluid begins to leak past the seal lip, leading to low fluid levels, contamination of surrounding components, and potential damage to bearings and internal assemblies if left unaddressed. Replacing the seal promptly with the correct OEM part restores the fluid barrier and protects the integrity of the surrounding drivetrain or hydraulic system.
