The Wacker Neuson is a genuine OEM 1/4X3/16X4-1/8 Key designed for CT36 and CT48 series walk-behind concrete power trowels. As a direct Wacker Neuson OEM part, the is sourced and manufactured to the same specifications as the original component installed at the factory. This key fits across multiple CT36 and CT48 configurations, including variable-speed and CE-compliant models, making it a straightforward service part for contractors maintaining their finishing equipment.
Key Features
- OEM-Spec Keyed Dimensions: — Cut to exact 1/4 x 3/16 x 4-1/8 inch dimensions, ensuring correct shaft-to-hub engagement with zero slop or misalignment in the drive train.
- Drop-In Shaft Fitment: — Designed to seat directly into the keyway without recutting or filing, allowing straightforward replacement during scheduled maintenance or after wear-related failure.
- Broad CT-Series Compatibility: — Confirmed fitment across CT36-8A-V, CT36-9-V, CT36AVP, CT36AVT, CT48-13A-V, CT48AVP, and CT48AVT walk-behind power trowel models, including CE variants.
- Torque Transfer Integrity: — A correctly sized key locks the rotating assembly to the shaft so full engine torque reaches the trowel blades; a worn or missing key causes blade slippage and uneven concrete finishing.
- Genuine Wacker Neuson OEM Part: — Supplied directly through the Wacker Neuson parts network, so material grade and dimensional tolerances match the original specification exactly.
A shaft key is a small but load-bearing component that locks a rotating hub, gear, or sprocket to a drive shaft, preventing relative rotation between the two parts. It transmits torque by sitting in matching keyways cut into both the shaft and the mating bore, creating a positive mechanical connection. When a key shears, deforms, or wears, the driven component can slip on the shaft, resulting in loss of blade drive, vibration, or uneven trowel pressure across the concrete surface — issues that become apparent quickly during finishing operations.
