The Wacker Neuson CT Gearbox is a genuine OEM component designed for the CT36 and CT48 walk-behind concrete power trowel series. This gearbox is a direct OEM replacement sourced from Wacker Neuson, covering a broad range of CT36 and CT48 configurations including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-9-V, CT36-400E, CT36-X, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V. As a genuine OEM part, the is built to the exact engineering specification of the original component — ensuring it installs and performs as intended without modification.

Key Features

  • Genuine OEM Gear Tolerancing — Manufactured to Wacker Neuson's original gear mesh and torque specifications, maintaining the power transfer characteristics the CT trowel was designed to deliver.
  • Drop-In Installation — Engineered to match the original bolt pattern and shaft interface on CT36 and CT48 trowel decks, allowing straightforward removal and reinstallation.
  • Broad CT Series Coverage — Fits a wide range of CT36 and CT48 model variants, including standard, EU, variable-pitch (V), and contractor (C) configurations across both 36-inch and 48-inch deck sizes.
  • Consistent Blade Speed and Float Quality — A properly functioning gearbox maintains correct blade RPM and pitch response, which directly affects surface finish quality; a worn unit causes erratic blade behavior and uneven float results.
  • Verified OEM Part Number — Part number 5000163432 is the current Wacker Neuson catalog reference for this CT Gearbox, ensuring you receive the correct assembly for your machine.

The CT Gearbox transfers power from the trowel's engine or motor to the rotating spider and finishing blades, controlling both blade speed and pitch angle. It is the mechanical core of the trowel's drive system — if the gearbox wears, develops excessive play, or fails, blade rotation becomes inconsistent and pitch adjustment is compromised, making it impossible to achieve a properly floated or finished concrete surface. Replacing a failed or worn gearbox with a genuine OEM unit restores full drive function and ensures the trowel operates within its intended performance range.
