Wacker Neuson 5000074018 Centrifugal Clutch W/1 Bore

The Wacker Neuson 5000074018 is a genuine OEM Centrifugal Clutch designed for the CT36 and CT48 series walk-behind concrete power trowels. As a direct OEM replacement, this clutch is sourced from Wacker Neuson and built to the same specifications as the original component installed on your machine. Fitment covers a broad range of CT36 and CT48 models including the CT36-8A, CT36-9, CT48-8A, CT48-9, CT48-11A, and AGP, AGT, ADP, ADT, and BDT variants in both standard and CE configurations. Whether you are running a 36-inch or 48-inch trowel, part number 5000074018 is the correct OEM clutch to restore full operation.

Key Features

• Genuine OEM Engagement Accuracy — Manufactured to Wacker Neuson's original centrifugal engagement specifications, ensuring the clutch engages at the correct RPM threshold for consistent rotor speed control.
• Drop-In Fitment for CT36 and CT48 Families — Installs directly into the power head assembly without modification, covering 36-inch and 48-inch walk-behind trowel configurations across AGP, AGT, ADP, ADT, and BDT variants.
• Smooth Power Transfer to the Rotor — A properly functioning centrifugal clutch allows the engine to reach operating speed before engaging the trowel blades, protecting the drivetrain and delivering a controlled, progressive startup every time.
• Operational Safety During Startup — The centrifugal clutch is a key safety element in the power transmission path; a worn or slipping clutch can cause unpredictable blade engagement, making timely replacement critical for operator safety.

The centrifugal clutch connects the engine to the trowel's rotor assembly and controls when power is transferred to the finishing blades. It works by using centrifugal force — as engine RPM rises, weighted shoes inside the clutch drum expand outward and engage the drum, transmitting drive to the rotor. This design allows the engine to idle freely without spinning the blades and only engages once a safe operating speed is reached. When the clutch wears, shoes may slip, engage too early, or fail to release, resulting in rough startups, inconsistent blade speed, excessive heat buildup, and premature wear on surrounding drivetrain components.
