The Wacker Neuson Oil Seal is a genuine OEM Oil Seal designed for the RD12-90 Double Drum Roller and CRT36-25 Ride-on Trowel series. As a factory-sourced component, it meets the original material and dimensional specifications Wacker Neuson engineers built into these machines. This seal covers both solid and foldable ROPS configurations of the RD12-90, as well as standard and wheel kit variants of the CRT36-25, making it the correct choice across the full range of these models. Ordering by part number ensures you receive the right seal the first time.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and compression specifications, delivering the same sealing integrity as the part that came off the production line.
- Drop-In Replacement — Matches the original bore diameter and lip geometry exactly, seating into the housing the same way as the factory-installed seal with no rework needed.
- Broad Model Coverage — Fits RD12-90 Double Drum Rollers (solid and foldable ROPS variants) and CRT36-25 Ride-on Trowels (including wheel kit and CRT36-26A-WK configurations).
- Prevents Lubricant Loss — A properly functioning oil seal keeps internal lubricant contained where it belongs, protecting rotating shafts and bearings from wear and heat buildup.
- Fluid Ingress Protection — The seal also blocks water, concrete slurry, and fine debris from entering the drivetrain — a critical function given the wet and abrasive environments these machines operate in.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so you can confirm authenticity and traceability against the original bill of materials.
An oil seal is a precisely fitted ring that sits around a rotating shaft and prevents lubrication oil from escaping the housing while blocking outside contaminants from getting in. On compaction rollers and ride-on trowels, these seals protect the drivetrain components — gears, bearings, and shafts — that keep the machine working under heavy load and in harsh site conditions. When an oil seal wears out or fails, lubricant leaks out rapidly and contaminants enter, leading to accelerated bearing wear and potential drivetrain damage that is far more costly to repair than a seal replacement.
