The Wacker Neuson Ring Key is a genuine OEM component designed for a broad range of Wacker Neuson tandem rollers and ride-on concrete trowels, including the RD12, RD16, and RD27 series rollers and the CRT36, CRT48, and CRT60 ride-on trowel families. Sourced directly from Wacker Neuson, this part carries the same specifications as the original hardware installed at the factory. The covers an extensive fitment range across both compaction and concrete finishing equipment lines, making it a commonly stocked service item for mixed Wacker Neuson fleets. Confirming your machine's model number before ordering ensures the correct fit for your specific unit.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring the key seats and retains correctly in the keyway without slop or stress concentration.
- Drop-In Hardware Replacement: — Matches the original ring key profile exactly, so installation requires only standard hand tools and no reworking of shafts or keyways.
- Wide Cross-Family Fitment: — Confirmed for RD12, RD16, and RD27 tandem rollers as well as CRT36, CRT48, and CRT60 ride-on trowel models, spanning both the compaction and concrete finishing equipment lines.
- Prevents Drive Slippage: — A worn or missing ring key allows mating components to rotate independently on the shaft, causing loss of drive transfer and potential damage to surrounding hardware; replacing it promptly restores positive torque transmission.
- Verified Wacker Neuson Part Number: — Order with confidence using part number 5000113119, cross-referenced directly against Wacker Neuson's OEM parts catalog for accuracy.
A ring key is a small but critical piece of hardware that locks a rotating component — such as a pulley, sprocket, gear, or drum hub — to its shaft, ensuring both turn together as a single unit. It sits in a machined slot called a keyway, bridging the shaft and the bore of the mating part to transmit torque and prevent relative rotation. When a ring key shears, deforms, or works loose, the driven component can spin freely on the shaft, resulting in lost drive, erratic machine behavior, and rapid wear to both the shaft and the bore of the affected component.
