The Wacker Neuson is a genuine OEM Machined Gearbox Cover designed for the CT36 and CT48 series walk-behind concrete power trowels. As a direct factory replacement, this cover is manufactured to the same tolerances and material specifications as the original, ensuring a correct fit within the gearbox assembly. It is compatible across an extensive range of CT36 and CT48 models, including CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT36-X, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V variants. Sourcing a genuine OEM component like the means no guesswork on fit or material grade — you get the exact part Wacker Neuson specifies for these machines.
Key Features
- Precision-Machined OEM Construction — Manufactured to Wacker Neuson's exact dimensional tolerances, ensuring the cover seats and seals correctly against the gearbox housing without gaps or misalignment.
- Drop-In Replacement for CT36 and CT48 Trowels — Engineered to align with the existing bolt pattern and mating surfaces on covered gearbox assemblies across both 36-inch and 48-inch CT model families.
- Broad CT-Series Compatibility — Confirmed fitment across CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-9-V, CT36-400E, CT36-X, CT36-X-C, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V models, including EU and variable-pitch variants.
- Protects Internal Gearbox Components — A properly fitted gearbox cover keeps contaminants, concrete slurry, and debris out of the gear train, directly affecting the service life of gears, bearings, and lubricant.
- Genuine Wacker Neuson OEM Part — Supplied as original equipment, part number 5000150977 matches factory records for these trowel models, eliminating compatibility uncertainty at the point of order.
The gearbox cover on a walk-behind concrete power trowel encloses and protects the gear train that transfers engine power to the trowel blade arms. It keeps gear oil contained and prevents abrasive material — particularly concrete slurry — from entering the gearbox housing and accelerating wear on internal components. A cracked, missing, or poorly fitting cover allows contamination to enter the gear assembly, leading to accelerated gear and bearing wear, lubricant loss, and eventually gearbox failure that takes the trowel out of service entirely. Replacing a damaged cover promptly with a correctly machined OEM part is one of the most cost-effective ways to protect the entire gearbox assembly.
