Wacker Neuson 5000074019 Centrifugal Clutch W/.75 Bore

The Wacker Neuson is a genuine OEM Centrifugal Clutch W/.75 Bore designed for CT30 and CT36 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this part meets the exact engineering specifications of the original component installed at the factory. It fits a wide range of CT30 and CT36 model variants, including ADT, AGT, BDT, and X-series configurations in both standard and CE-compliant builds. If your trowel is slipping, losing drive engagement, or failing to transfer power smoothly to the rotor assembly, part number is the correct OEM replacement to restore proper operation.

Key Features

• Correct Bore Diameter for Direct Installation — Machined to a .75-inch bore, this clutch seats precisely onto the crankshaft without modification, ensuring immediate engagement with the drive system.
• Genuine OEM Part from Wacker Neuson — Manufactured to the same centrifugal engagement tolerances as the original, preserving consistent RPM-based clutch engagement that the CT series trowels are calibrated around.
• Broad CT30 and CT36 Series Compatibility — Confirmed fitment across CT30ADT, CT30AGT, CT36ADT, CT36AGT, CT36BDT, CT36-5A, CT36-6, CT36-X, and CT36ADP variants, covering both 762mm/30in and 915mm/36in walk-behind trowel platforms.
• Restores Clean Power Transfer to the Rotor — A worn or slipping centrifugal clutch causes uneven blade speed and poor trowel finish quality; replacing with part 5000074019 brings engagement back to the correct engine RPM threshold.
• Operator Safety Through Predictable Clutch Engagement — A centrifugal clutch that engages erratically or fails to disengage at idle creates an unpredictable machine. This OEM replacement restores the smooth, RPM-governed engagement behavior the trowel was designed to deliver.

The centrifugal clutch connects the engine to the trowel's rotor and blade assembly. At idle, the clutch remains disengaged so the blades stay stationary; as engine RPM rises, centrifugal force causes the clutch shoes to expand outward and lock into the drum, transferring power smoothly to the rotor. This automatic engagement mechanism protects both the operator and the engine during startup. When the clutch shoes wear down or the springs weaken, the clutch may slip under load, engage too early at low RPM, or fail to release cleanly at idle — all of which affect finish quality and machine control. Replacing the clutch assembly with a correctly sized OEM unit like the 5000074019 restores the designed engagement behavior and protects downstream drivetrain components.
