The Wacker Neuson Ring Gear is a genuine OEM Ring Gear designed for the RD12-90 Double Drum Roller and CRT36-25 Ride-on Trowel series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component — no guesswork, no fitment surprises. It is a verified direct replacement for both solid ROPS and foldable ROPS configurations of the RD12-90, as well as all CRT36-25 variants including the wheel kit and CRT36-26A configurations.
Key Features
- Genuine OEM Tooth Geometry — Manufactured to Wacker Neuson's original tooth profile and hardness specification, ensuring smooth, consistent power transfer through the drivetrain.
- Direct Drivetrain Replacement — Engineered to seat and mesh exactly as the original, so installation aligns with existing housings and mating gears without reworking the assembly.
- Broad Model Coverage — Fits RD12-90 Double Drum Rollers (solid ROPS and foldable ROPS) and the full CRT36-25 Ride-on Trowel range, including wheel kit and CRT36-26A variants.
- Sustained Power Transmission — A correctly functioning Ring Gear delivers full torque to the drum or rotor drive; a worn or chipped gear causes slippage, vibration, and uneven compaction or finishing performance.
- Verified Part Number Fit — Part number 5000215880 is confirmed across multiple Wacker Neuson machine configurations, giving you confidence you are ordering the right component the first time.
The Ring Gear is a critical component in the power transmission path of the machine's drive system. It meshes with a pinion or drive gear to multiply torque and transfer rotational force to the drum assembly on rollers or the rotor drive on ride-on trowels — directly controlling how effectively the machine compacts or finishes a surface. When the Ring Gear wears, chips, or fails, the result is lost drive, increased mechanical noise, and inconsistent output that compromises the quality of the work and places added stress on surrounding drivetrain components.
