The Wacker Neuson Inner Rotor is a genuine OEM component designed for the RD12-90 Tandem Roller and CRT36-25 Ride-on Trowel series. Sourced directly from Wacker Neuson, this part meets the exact dimensional and performance specifications required for proper operation. Confirmed fitment covers RD12-90 models with both solid and foldable ROPS configurations, as well as CRT36-25 Ride-on Trowels including the Wheel Kit variant. When you order the, you're getting the same part that went into the machine at the factory — no guesswork, no adaptation.
Key Features
- OEM-Grade Rotor Geometry — Manufactured to the exact dimensional tolerances required for correct magnetic alignment and rotational balance within the assembly.
- Direct Drop-In Replacement — Engineered to seat and connect exactly as the original, using the same mounting interface as the part it replaces.
- Broad Model Coverage — Fits RD12-90 Tandem Rollers (solid and foldable ROPS) and CRT36-25 Ride-on Trowels, including the Wheel Kit configuration.
- Consistent Power Transfer — A correctly spec'd inner rotor maintains efficient energy conversion within the machine's electrical system, supporting steady output under load.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, ensuring material composition and finish match the original production specification.
The inner rotor is a core rotating component within the machine's electrical generating or motor assembly. It works in close conjunction with the outer stator to produce or transfer electromagnetic energy, enabling the machine to generate the power needed to drive its working functions. When the inner rotor wears, becomes damaged, or loses its dimensional integrity, the result is reduced output efficiency, increased heat buildup, irregular performance, or complete loss of electrical function — making prompt replacement critical to keeping the machine operational.
