The Wacker Neuson Gearbox Cover is a genuine OEM component designed for the CT36 and CT48 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this part carries the same fit, form, and material specification as the original — ensuring a seamless drop-in replacement with no guesswork. Compatibility spans a wide range of CT36 and CT48 models, including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT36-X, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V. When your trowel's gearbox cover is cracked, damaged, or missing, the restores proper protection and keeps your finishing equipment back on the slab fast.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact material and dimensional spec, so the cover fits flush and seals the gearbox housing the same way the original did from the factory.
- Direct-Fit Replacement: — Mounts using the existing bolt pattern and housing geometry on CT36 and CT48 trowels — no drilling, trimming, or adapting required.
- Broad CT-Series Compatibility: — Fits a wide span of CT36 and CT48 walk-behind power trowel variants, including A-series, V-series, EU-spec, and X-series models.
- Gearbox Protection Restored: — A correctly fitted cover shields the gearbox internals from concrete slurry, water, and debris — the leading causes of premature gear and bearing wear on finishing trowels.
- Verified Part Number: — Part number 5000158801 cross-references directly to the CT36 and CT48 model lines, giving you confidence you're ordering the right cover before it ships.
The gearbox cover on a walk-behind concrete power trowel serves as the primary barrier between the gearbox internals and the harsh finishing environment — concrete slurry, water, and fine aggregate particles that can accelerate wear on gears and bearings if allowed to enter the housing. A damaged or missing cover exposes the gearbox to contamination that shortens component life and can lead to costly drivetrain failures mid-pour. Replacing a cracked or broken cover promptly with the correct OEM part keeps the gearbox sealed and lubricated, maintaining smooth power transfer from the engine to the trowel blades.
