The Wacker Neuson is a genuine OEM Square Key 3/16 X 3.5 designed for the CT48AVP, CT48AVT, CT36AVT, and CT36AVP series variable speed walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this square key is an exact match to the original component installed on these machines at the factory. It fits both standard and CE-compliant variants across the 36-inch and 48-inch CT trowel families. When you need a verified replacement to get your trowel back in service, part number is the correct choice.
Key Features
- OEM-Exact Dimensions — Manufactured to the precise 3/16 x 3.5 specification required for correct torque transfer in Wacker Neuson CT-series trowels.
- Drop-In Shaft Fit — Seats directly into the keyway groove on the trowel's drive shaft without modification, restoring the original mechanical connection.
- Broad CT-Series Coverage — Compatible with CT48AVP, CT48AVT, CT36AVP, and CT36AVT models, including both standard and CE-rated configurations.
- Drive Integrity Restored — A worn or sheared square key allows the shaft and mating component to slip, causing loss of rotor drive and uneven finishing performance; this OEM key restores positive engagement.
- Genuine Wacker Neuson Part — Supplied as a genuine OEM component, ensuring the material hardness and dimensional tolerances match the original specification for this drivetrain application.
A square key is a small but critical drivetrain component that locks a rotating shaft to a hub, gear, or sprocket, preventing the two from spinning independently of each other. In a walk-behind concrete trowel, the square key transmits engine torque through the drive assembly to the finishing blades — if the key shears or wears, the rotor loses drive and the trowel can no longer finish concrete properly. Replacing a failed key promptly with the correct OEM part restores full power transmission and prevents secondary damage to the shaft or hub keyway.
