The Wacker Neuson 5200019994 is a genuine OEM Exhaust Manifold designed for the APT4T and APT4S series self-priming pumps. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component fitted to these machines at the factory. It is compatible with the full range of APT4T and APT4S configurations, including Electric Brake, Surge Brake, and Cold Weather variants. If you are restoring exhaust flow or replacing a cracked or damaged manifold on one of these pump units, part number 5200019994 is the correct direct replacement.
Key Features
- Genuine OEM Casting Integrity — Manufactured to Wacker Neuson's original specifications, ensuring correct port geometry, wall thickness, and heat tolerance for sustained pump engine operation.
- Drop-In Fitment — Engineered to match the original mounting flange layout on APT4T and APT4S engines, allowing a straightforward bolt-on installation with no rework to surrounding components.
- Broad APT Series Coverage — Fits the APT4T (Electric Brake, Surge Brake) and APT4S (w/Skid) families, including all Cold Weather variants, across multiple machine configurations.
- Protects Engine Performance — A correctly sealed exhaust manifold maintains proper scavenging of combustion gases, supporting consistent power output and efficient fuel combustion in the pump engine.
- Exhaust Integrity and Operator Safety — A cracked or failed manifold can direct hot exhaust gases toward fuel lines, wiring, and the operator — replacing a compromised manifold promptly is a critical safety measure.
The exhaust manifold collects burned combustion gases from the engine's cylinder head and channels them into the exhaust system to be safely routed away from the machine. On pump engines like those in the APT4T and APT4S series, a sound manifold is essential for maintaining correct back pressure and preventing hot gas leaks that can damage nearby components or reduce engine efficiency. When a manifold cracks or warps — common results of repeated heat cycling — exhaust gases can escape at the joint, causing rough running, loss of power, and potential safety hazards around fuel and electrical components.
