Wacker Neuson 5000115699 Key A10 X 8 X 16

The Wacker Neuson Key A10 X 8 X 16 is a genuine OEM component designed for the RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, RTx-SC2, RT560, RT820, and HTC15 series remote-controlled vibratory trench rollers. As a genuine Wacker Neuson part, the is manufactured to the same tolerances and material specifications as the original, ensuring a correct, secure fit in the drivetrain assembly. This key is used across a broad range of trench roller configurations — including smooth drum, padfoot, and Compatec-equipped variants — making it a widely applicable service part for fleets running multiple RT-series machines. Keeping a genuine OEM Key A10 X 8 X 16 on hand means drivetrain repairs can be completed quickly and correctly the first time.

Key Features

• Genuine OEM Material Integrity — Manufactured to Wacker Neuson's hardness and dimensional specifications for a woodruff/parallel key, ensuring the torque-transfer interface between shaft and hub performs as designed.
• Direct Drivetrain Fit — Sized A10 X 8 X 16 to seat precisely in the keyway slot, restoring the positive mechanical connection between rotating components without secondary machining or fitting.
• Broad RT-Series Compatibility — Confirmed fitment across RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, RTx-SC2, RT560, RT820, and HTC15 trench roller families, covering both SC2 and SC3 generation machines.
• Drivetrain Power Transfer — A correctly seated key locks the shaft-to-hub relationship under vibratory and traction loads; a worn or sheared key causes slippage, loss of drum drive, and accelerated keyway damage.
• Verified OEM Part Number — Sourced directly from Wacker Neuson, part 5000115699 matches the original engineering drawing, eliminating the fitment risk associated with incorrectly sized key stock.

A drive key is a small but critical mechanical fastener that locks a rotating shaft to a mating hub, gear, sprocket, or drum — preventing the two from rotating independently under load. In a vibratory trench roller, drive keys transmit the torque generated by the hydraulic drive system directly to the drum or gearbox components. When a key shears or wears, the shaft spins freely inside the hub, resulting in a complete loss of drum drive or compaction output. Because trench rollers operate under continuous vibratory stress and reversing load cycles, key integrity is essential to maintaining consistent compaction performance and avoiding secondary damage to the keyway itself.
