Wacker Neuson 5000080800 Worm Gear Kit

The Wacker Neuson Worm Gear Kit is a genuine OEM replacement designed for CT30 and CT36 series walk-behind concrete power trowels. This kit covers a broad range of gas, diesel, and electric CT-series models in both standard and CE configurations, including the CT30AGT, CT30ADT, CT36AGP, CT36ADP, CT36ADT, CT36AGT, CT36BDT, CT36EDT, CT30EDT, and their E-suffix variants. As a genuine Wacker Neuson part, the is manufactured to the same tolerances as the components originally installed at the factory, ensuring the pitch and mesh geometry of the worm and gear are correct for smooth, consistent blade pitch adjustment. This kit is the right choice when the pitch control on your trowel becomes stiff, erratic, or unresponsive.

Key Features

• Correct Gear Mesh Geometry — Worm and gear profiles are matched to OEM tooth form, maintaining accurate blade pitch response throughout the full adjustment range.
• Genuine OEM Quality — Manufactured by Wacker Neuson to the same material grade and dimensional spec as the original kit, ensuring proper load distribution across the worm drive.
• Broad CT-Series Coverage — Fits 30-inch (762mm) and 36-inch (915mm) CT-series walk-behind trowels including gas, diesel, and electric variants in standard and CE configurations.
• Kit Format for Complete Service — Includes both worm and gear components together, so worn mating surfaces are replaced as a matched set rather than individually.
• Restores Blade Pitch Control — A worn or stripped worm gear set causes loss of blade angle adjustment, reducing finishing quality; replacing this kit restores precise, consistent pitch control.

The worm gear kit is the core of the blade pitch adjustment mechanism on a walk-behind concrete power trowel. The worm drive converts operator input at the pitch control handle into precise angular movement of the trowel blades, allowing the operator to dial in the correct blade angle for each stage of the finishing pass. When the worm or gear teeth wear or strip, the pitch adjustment becomes loose, sticky, or completely non-functional, making it impossible to achieve a consistent surface finish. Replacing both components together as a matched kit ensures the drive surfaces engage correctly and the adjustment feels positive and predictable from the moment the machine is put back to work.
