The Wacker Neuson is a genuine OEM Woodruff Key designed for a broad range of Wacker Neuson equipment, including the PT6LT and PT6LS trash pumps, RT560 and RT820 vibratory trench rollers, and DPU 100-70 and DPU 9070 reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this Woodruff Key meets the exact dimensional and material standards of the original component. It drops into the same keyway position as the factory part, requiring no rework or modification to the shaft or hub. Whether you are servicing a pump, a trench roller, or a heavy-duty reversible plate, the delivers a correct-specification fit across all covered configurations.
Key Features
- Genuine OEM Metallurgy — Manufactured to Wacker Neuson's exact hardness and dimensional tolerances, ensuring the key transmits torque without shearing or deforming under load.
- Broad Cross-Family Compatibility — A single part number covers PT6LT and PT6LS trash pumps, RT560 and RT820 vibratory trench rollers, and DPU 100-70 and DPU 9070 reversible vibratory plate compactors.
- Direct Shaft-to-Hub Engagement — The semi-circular profile seats fully into the mating keyway on the shaft and hub, locking rotational alignment the moment it is seated.
- Torque Integrity Restored — A worn or missing Woodruff Key causes slippage between the shaft and driven component; replacing it with part 5000063612 restores full power transfer to the pump impeller, roller drum drive, or plate exciter.
- Verified OEM Part Number — Part number 5000063612 is confirmed against Wacker Neuson's parts documentation for every listed model, so you can order with confidence before the machine goes down.
A Woodruff Key is a small, semi-circular metal key that sits in a matching slot — called a keyway — cut into a rotating shaft and the hub or pulley mounted on it. Its job is to lock those two components together rotationally so that torque is transmitted cleanly from the shaft to the driven part, whether that is a pump impeller, a belt pulley, or a drive gear. Because the key is designed to be the weakest link in the drivetrain, it can shear under shock loads rather than allowing damage to spread to the shaft or hub — but a worn or missing key will cause the shaft and hub to spin independently, resulting in total loss of power delivery and potential damage to surrounding components if left unchecked.
