The Wacker Neuson Outer Rotor is a genuine OEM component designed for the RD12-90 Double Drum Roller and CRT36-25 Ride-on Trowel series. As a direct factory part, is manufactured to the exact dimensional and material tolerances required by these machines, ensuring a correct installation without guesswork. This Outer Rotor is confirmed compatible with both the RD12-90 with Solid ROPS, the RD12-90 with Foldable ROPS, and both CRT36-25 Ride-on Trowel configurations including the Wheel Kit variant.
Key Features
- Exact OEM Rotor Geometry — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring correct magnetic air gap and concentricity within the motor or generator assembly.
- Direct Drop-In Replacement — Engineered to mount and align to the original shaft and housing interfaces on the RD12-90 and CRT36-25, fitting the way the factory-original part does.
- Broad Series Compatibility — Fits RD12-90 Tandem Rollers (Solid and Foldable ROPS variants) and CRT36-25 915mm Ride-on Trowels, covering multiple machine configurations with a single part number.
- Sustained Output Consistency — A correctly installed Outer Rotor maintains steady rotational energy transfer; a worn or damaged rotor causes vibration, reduced output, and accelerated wear on surrounding components.
- Genuine Wacker Neuson Part — Sourced directly through the OEM supply chain, carrying the part number 5000215222 as it appears in official Wacker Neuson parts documentation.
The Outer Rotor is the rotating element within an electric motor or generator assembly. It spins around a fixed inner stator, and the interaction between the rotor and stator windings or magnets is what generates or transfers rotational force. On compaction and finishing equipment like the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel, this component is critical to consistent power delivery. When the Outer Rotor becomes worn, damaged, or out of balance, the result is typically vibration, loss of power output, increased heat, and stress on bearings and adjacent drivetrain parts.
