The Wacker Neuson is a genuine OEM Key A14 X 9 X 50 designed for the RT and RTL/RTK series remote-controlled vibratory trench rollers. Sourced directly from Wacker Neuson, this key meets the exact dimensional and material standards of the original component. Fitment spans a wide range of trench roller configurations including the RT56-SC, RT82-SC, RT82-SC2, RTx-SC2, RTLx-SC3, and RTKx-SC3 series. Keeping the correct key in service ensures drivetrain power transfer stays tight and accurate across the full range of compatible machines.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact A14 x 9 x 50 profile specified by Wacker Neuson, ensuring correct seating in the keyway without slop or stress concentration.
- Direct Drop-In Replacement — Matches the original key slot geometry on RT and RTL/RTK series trench rollers for a straightforward swap during drivetrain service.
- Broad Trench Roller Compatibility — Fits RT56-SC, RT82-SC, RT82-SC2, RTx-SC2, RTLx-SC3, and RTKx-SC3 series machines, covering both SC2 and SC3 generation platforms.
- Positive Power Transmission — A correctly fitted woodruff or parallel key locks rotating components to their shaft, preventing slippage that can cause accelerated wear on mating drivetrain parts.
- Genuine Part Assurance — As a genuine Wacker Neuson OEM component, part number 5000116872 is held to the same material hardness and tolerance standards as the key it replaces.
A machine key is a small but critical drivetrain component that fits into a machined slot — called a keyway — between a shaft and a mating hub, gear, sprocket, or pulley. Its job is to lock those two parts together rotationally so that torque is transferred cleanly without slipping. On remote-controlled vibratory trench rollers like the RT and RTL/RTK series, the key plays a direct role in transmitting drive power to the drum or exciter assemblies. When a key wears, deforms, or shears, the connected component can slip or spin free on the shaft, resulting in lost drive, vibration irregularities, and potential damage to the surrounding shaft and hub surfaces if the machine continues to run.
