The Wacker Neuson Gearbox Side Cover is a genuine OEM component designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels. As a direct OEM replacement, this cover is manufactured to the same specifications as the original part, ensuring a proper fit across the full range of 30-inch, 36-inch, and 48-inch CT series trowels — including gasoline, diesel, electric, and variable-speed configurations. Whether you are servicing a standard walk-behind or a CE-compliant model, part number is the correct replacement for this application. Keep your trowel running at full capacity by replacing worn or damaged covers with the factory-correct part.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the cover seats correctly and provides the same level of gearbox protection as the factory-installed part.
- Drop-In Replacement: — Matches original mounting points and profile on CT series trowels, allowing straightforward installation without reworking hardware or housings.
- Broad CT Series Compatibility: — Fits CT30, CT36, and CT48 walk-behind trowels across gasoline (AGP, AGT), diesel (ADP, ADT, BDT), electric (EDT), and variable-speed (AVP, AVT) variants, including CE-compliant units.
- Gearbox Protection: — Shields internal gearbox components from concrete slurry, moisture, and debris during finishing operations — contaminants that accelerate wear on gears and bearings when a cover is cracked or missing.
- Verified Part Number: — Order with confidence using Wacker Neuson OEM part number 5000073321, cross-referenced across the full CT series model range listed above.
The gearbox side cover on a walk-behind concrete trowel encloses and protects the drive gearbox that transfers engine or motor power to the trowel blades. By keeping concrete slurry, water, and grit out of the gear housing, it directly extends the service life of the internal gears, shafts, and bearings. A cracked, broken, or missing cover exposes these components to the harsh wet-concrete environment on a finishing deck, leading to accelerated wear and potential gearbox failure.
