The Wacker Neuson is a genuine OEM Gearbox Side Cover designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels. As a direct OEM replacement sourced through authorized channels, this cover is produced to the same specifications as the original part fitted at the factory. It is compatible across a broad range of CT series configurations, including gas, diesel, electric, variable speed, and CE-compliant models in 30-inch, 36-inch, and 48-inch blade sizes. When fitment accuracy matters on a finishing machine, specifying the correct OEM part number — — eliminates guesswork and keeps your trowel running as intended.
Key Features
- OEM-Matched Enclosure Integrity — Manufactured to the same dimensional and material spec as the original, ensuring the gearbox housing seals correctly and contaminants are kept out of the drive assembly.
- Drop-In Installation — Mounts directly to the gearbox housing using the original fastener pattern, with no drilling, filing, or adapter hardware required.
- Broad CT Series Coverage — Fits CT30, CT36, and CT48 walk-behind trowels across gas, diesel, electric, and variable speed variants, including standard and CE-compliant configurations.
- Protects Critical Drive Components — A damaged or missing gearbox side cover exposes the internal gear set and bearings to concrete slurry, water, and debris, accelerating wear and leading to costly gearbox failure.
- Genuine Wacker Neuson OEM Part — Carries the full Wacker Neuson OEM designation, so you receive the exact part validated for use in these trowels — not an approximation.
The gearbox side cover encloses the side of the trowel's gearbox housing, shielding the internal gear set, shafts, and bearings from the wet, abrasive environment of a concrete finishing operation. Without a properly seated cover, concrete slurry and moisture can enter the gearbox, contaminating lubricant and grinding away at precision components. Keeping this cover intact and undamaged is a straightforward maintenance step that directly extends gearbox service life and preserves the smooth, consistent rotor speed that quality concrete finishing demands.
