The Wacker Neuson Exhaust Manifold is a genuine OEM component designed for CRT48 ride-on concrete trowels and the CT48-13A-V walk-behind trowel. Sourced directly from Wacker Neuson, this manifold meets the exact engineering specifications of the original part. Confirmed fitment spans multiple CRT48-31V, CRT48-34V, and CT48-13A-V variants, including high-speed and electronic steering configurations. When you need a straight-swap replacement to restore proper exhaust function, part number is the correct choice.
Key Features
- OEM Exhaust Integrity — Cast and machined to original port geometry, ensuring correct exhaust gas flow and back-pressure balance for the trowel's engine.
- Direct Bolt-On Replacement — Matches OEM mounting flange dimensions and gasket surfaces on the CRT48 and CT48-13A-V engine assemblies for a straightforward installation.
- Broad CRT48 and CT48 Coverage — Fits CRT48-31V, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, CRT48-31V-ES-E, CRT48-34V, and CT48-13A-V trowel configurations.
- Sustained Engine Performance — A properly sealed exhaust manifold keeps combustion gases routed away from the operator and prevents the power loss and rough running associated with exhaust leaks.
- Operator Safety Compliance — Exhaust leaks at the manifold can expose operators to carbon monoxide and excessive heat; replacing a cracked or warped manifold with a genuine OEM unit restores safe exhaust containment.
The exhaust manifold collects spent combustion gases from each cylinder port and channels them into the exhaust system, directing heat and fumes safely away from the engine and operator. On a concrete trowel working in enclosed or semi-enclosed finishing environments, a cracked or warped manifold creates an exhaust leak that raises the risk of carbon monoxide exposure and reduces engine efficiency. Left unaddressed, a failed manifold can cause overheating, rough idle, and accelerated wear on surrounding engine components.
