The Wacker Neuson is a genuine OEM Key 3/8 X 4-3/4 designed for the CRT46KHN and CRT46KHO ride-on concrete trowels. As a direct factory part, it is manufactured to the exact dimensions and material specifications required by Wacker Neuson for these machines. This key seats precisely within the drivetrain to maintain positive power transfer between rotating components. Confirming your machine model before ordering ensures a correct, ready-to-install fit.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 3/8 x 4-3/4 inch specification, ensuring the key fills the keyway without play or slop that could cause premature wear.
- Direct Factory Replacement — Sourced directly from Wacker Neuson, this part slots into the original keyway without machining, filing, or shimming.
- Confirmed Fitment for CRT46 Series — Verified for CRT46KHN and CRT46KHO ride-on concrete trowels, keeping your part selection accurate from the start.
- Positive Power Transfer — A correctly sized key locks the shaft and hub together so rotor torque is transmitted cleanly; a worn or undersized key allows slippage that damages both the shaft and the hub bore.
- Hardened for Drivetrain Loads — Keys are subject to shear forces every time the trowel engages load; OEM material grade ensures the part holds up under the cyclic stress of concrete finishing work.
A drive key is a small but critical component that sits in a machined slot — called a keyway — between a rotating shaft and the hub or gear mounted on it. Its job is to lock these two parts together so that torque from the engine or transmission is transferred without slip. On a ride-on concrete trowel like the CRT46 series, the drivetrain is under continuous load during finishing passes, putting steady shear stress on the key. When a key wears, shears, or goes missing, the shaft spins freely inside the hub, the driven component stops turning, and continued operation risks scoring both the shaft and the bore — turning a low-cost fix into a costly repair.
