The Wacker Neuson Oil Seal is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory tandem rollers, including standard and traction control configurations. As a factory-sourced part, the meets the same material and dimensional standards as the seal installed at the time of manufacture. This Oil Seal is confirmed to fit across multiple machine numbers within the RD27-100 and RD27-120 roller families, making it the straightforward choice when servicing these machines.
Key Features
- Genuine OEM Sealing Performance — Manufactured to Wacker Neuson's original material and compression specifications, ensuring the seal conforms correctly to mating surfaces and maintains a durable, leak-free barrier.
- Direct-Fit Replacement — Matches the original seat geometry and outer diameter of the production seal, dropping into position without modification to housing or shaft dimensions.
- Broad RD27 Series Coverage — Verified fitment across RD27-100 and RD27-120 configurations, including both standard hydrostatic vibratory roller and traction control variants.
- Protects Hydraulic and Drive System Integrity — A worn or failed oil seal allows fluid loss and contaminant ingress that accelerates wear on bearings, shafts, and hydraulic components throughout the drivetrain.
- Prevents Unplanned Fluid Loss — Maintaining a properly seated oil seal is essential on hydrostatic roller systems where oil level and circuit pressure directly affect drum drive and compaction output.
An oil seal is a precision-fit ring installed around a rotating shaft to retain lubricant inside a housing and block dirt, water, and debris from entering. On a hydrostatic vibratory roller like the RD27 series, oil seals are critical at drum drive shafts, wheel motor interfaces, and gearbox outputs where constant rotation and vibration place ongoing stress on sealing lips. When an oil seal wears, cracks, or is displaced, fluid escapes the housing, lubricant levels drop, and unprotected metal surfaces begin to wear prematurely — often leading to more extensive and costly drivetrain damage if not addressed promptly.
