The Wacker Neuson is a genuine OEM Gearbox Assembly CT Variable designed for the CT36AVP, CT36AVT, CT48AVP, and CT48AVT variable speed walk-behind concrete power trowels. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original unit installed at the factory, ensuring proper fit and function within the drivetrain of your Wacker Neuson trowel. Coverage spans both the 915mm/36-inch and 1220mm/48-inch variable speed models, including CE-compliant variants. When your gearbox begins to show signs of wear or failure, replacing it with the correct OEM part keeps your trowel running at the output and finish quality that concrete flatwork demands.
Key Features
- OEM-Grade Gear Tolerancing: — Manufactured to the same internal gear mesh and bearing clearance specifications as the original, sustaining smooth, consistent power transfer to the trowel blades.
- Variable Speed Drivetrain Compatibility: — Engineered specifically for the CT variable speed drivetrain, ensuring correct engagement with the variable speed input without shimming or adaptation.
- Broad CT Series Coverage: — Fits CT36AVP, CT36AVT, CT48AVP, and CT48AVT models in both standard and CE-compliant configurations, covering 36-inch and 48-inch walk-behind trowels.
- Restored Blade Speed Control: — A functioning gearbox maintains the operator's ability to dial in blade pitch and rotation speed precisely — critical for achieving the correct finish on flatwork concrete.
- Verified Genuine OEM Part: — Sourced directly through the Wacker Neuson OEM parts channel under part number 5000151057, eliminating fitment guesswork on a drivetrain-critical assembly.
The gearbox assembly is the central power transmission component in a walk-behind concrete power trowel. It receives rotational input from the engine and converts it into the controlled blade rotation that smooths and finishes a concrete slab. On variable speed models like the CT36AVP, CT36AVT, CT48AVP, and CT48AVT, the gearbox also works in conjunction with the variable speed system to allow the operator to adjust blade speed to suit the concrete's set stage and the desired finish. When the gearbox wears or fails, blade rotation becomes erratic or stops entirely, making it impossible to achieve a consistent surface finish — a costly outcome on any flatwork pour.
