The Wacker Neuson is a genuine OEM Brush Assembly designed for the CRT48-25K-L, CRT48-25K-H, CRT36-23K-H, and CRT36-25K-H ride-on concrete trowels. As a factory-sourced component, this Brush Assembly meets the exact electrical specifications required by Wacker Neuson for safe and consistent operation across these machines. Whether you are servicing a 1220mm/48-inch or a 915mm/36-inch ride-on trowel, part number is the correct OEM replacement. Sourcing a genuine Wacker Neuson assembly ensures that the carbon brush material, brush holder dimensions, and contact geometry match the original design without compromise.
Key Features
- OEM-Matched Carbon Brush Material — Manufactured to the same conductivity and wear-rate specification as the original, ensuring consistent current transfer across the brush contact surface.
- Drop-In Fitment for CRT Ride-On Trowels — Engineered to seat directly into the brush holder on CRT48-25K and CRT36 series machines, preserving correct spring tension and contact alignment.
- Covers Key CRT Model Variants — Confirmed fitment for the CRT48-25K-L low-speed, CRT48-25K-H high-speed, CRT36-23K-H, and CRT36-25K-H ride-on trowel configurations.
- Protects Motor Commutator Integrity — A correctly sized brush maintains even commutator wear; an undersized or incorrect brush causes arcing, scoring, and accelerated motor failure.
- Electrical Safety Compliance — Using a genuine OEM brush with correct resistance and contact pressure is critical on ride-on trowel electrical systems to prevent heat buildup and potential arc faults.
The Brush Assembly is a wear component in the electric motor circuit of the ride-on trowel, responsible for maintaining sliding electrical contact between the stationary wiring and the rotating armature or commutator. It carries current continuously during machine operation, so the brush material and dimensional fit are critical — a worn or incorrect brush increases electrical resistance, generates excess heat, and causes erratic motor performance or complete loss of drive. Replacing the brush assembly at the correct service interval keeps the motor commutator clean and undamaged, extending overall motor service life on your CRT ride-on trowel.
