The Wacker Neuson is a genuine OEM Breather Hose 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, part is manufactured to the exact dimensions and material specifications required for proper crankcase ventilation on these machines. It installs as a direct replacement with no alteration needed to adjacent hose routing or fittings. Confirm your model number before ordering to ensure compatibility with your specific CRT series trowel.
Key Features
- Genuine OEM Material Integrity — Factory-sourced hose stock delivers the correct inner diameter, wall thickness, and heat-resistant compound needed to handle crankcase vapors without cracking or collapsing under operating temperatures.
- Drop-In Replacement — Matches original hose routing and end dimensions on the CRT ride-on trowel engine, so the connection to the breather port seats correctly without reworking existing clamps or brackets.
- Broad CRT Series Coverage — Fits the 48-inch low-speed CRT48-25K-L, 48-inch high-speed CRT48-25K-H, and both 36-inch high-speed CRT36-23K-H and CRT36-25K-H ride-on trowel models.
- Crankcase Pressure Control — A sound breather hose keeps crankcase pressure balanced, protecting engine seals and preventing oil vapor from escaping into areas that can cause contamination or fouling on the trowel deck.
- Fuel and Vapor System Safety — A cracked or collapsed breather hose can allow uncontrolled crankcase pressure buildup, increasing the risk of seal failure and oil leaks on a machine operating on freshly placed concrete slabs.
The breather hose routes crankcase gases away from the engine block, allowing built-up pressure from combustion blow-by to vent in a controlled manner rather than forcing past gaskets and oil seals. On ride-on concrete trowels like the CRT48 and CRT36 series, maintaining this ventilation path is critical because the engine operates under sustained load while the operator maneuvers across a fresh slab. When the hose cracks, collapses, or pulls free at either connection point, crankcase pressure rises, accelerating wear on seals and often causing oil leaks that contaminate the work surface below.
