Wacker Neuson 5000074018 Centrifugal Clutch W/1 Bore

The Wacker Neuson is a genuine OEM Centrifugal Clutch W/1 Bore designed for the CT36 and CT48 series walk-behind concrete power trowels. As a direct OEM replacement, part is manufactured to the same specifications as the original component, ensuring a proper fit within the drivetrain of your Wacker Neuson trowel. Fitment covers a wide range of CT36 and CT48 configurations, including AGP, ADP, AGT, ADT, BDT, and standard 8A, 9, 11A engine variants across both 915mm/36in and 1220mm/48in models. When you need a centrifugal clutch that installs correctly the first time, this is the part to order.

Key Features

• Genuine OEM Engagement Spec: — Manufactured to Wacker Neuson's original engagement RPM and torque transfer specifications, so the clutch picks up load at the correct engine speed — no slipping at idle or harsh engagement under power.
• 1-Inch Bore, Drop-In Fitment: — The 1-inch bore dimension matches the crankshaft output shaft on compatible CT-series engines, allowing direct installation without modification to the shaft or housing.
• Broad CT36 and CT48 Coverage: — Confirmed fitment across CT36-8A, CT36-9, CT48-8A, CT48-9, CT48-11A, and a full range of AGP, ADP, AGT, ADT, and BDT variants in both standard and CE configurations.
• Smooth Power Transfer to the Trowel Blades: — A correctly functioning centrifugal clutch allows the engine to reach operating speed before load is applied to the rotor, protecting the engine and delivering consistent blade rotation for a quality concrete finish.
• Operator Safety — Controlled Engagement: — The centrifugal mechanism ensures the rotor cannot spin at idle, which is a critical safety function on walk-behind trowels where unintended blade movement presents a direct hazard to the operator.

The centrifugal clutch connects the engine output shaft to the trowel's rotor assembly and controls when power is transmitted to the spinning blades. It works by using centrifugal force generated as engine RPM rises — weighted flyweights expand outward and engage a drum that drives the rotor, meaning the blades only begin to turn once the engine reaches a set operating speed. When the clutch wears out or the flyweights or springs lose tension, symptoms include blade slip under load, failure to engage at normal operating RPM, or in severe cases, complete loss of drive to the rotor — all of which interrupt the finishing pass and can damage a concrete pour in progress.
