The Wacker Neuson 5100017220 Injection Nozzle is a genuine OEM component designed for PT2H series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this is an exact-match replacement that meets the original engineering specifications for fuel delivery in the PT2H engine. If your pump is hard to start, running rough, or showing signs of poor fuel atomization, the injection nozzle is a primary suspect and this is the correct replacement part. Confirm your model number against the PT2H fitment before ordering to ensure a direct match.
Key Features
- OEM-Calibrated Spray Pattern — Manufactured to the original fuel atomization spec, ensuring the correct spray angle and droplet size for efficient combustion in the PT2H engine.
- Drop-In Engine Compatibility — Engineered to seat directly into the PT2H fuel injection system with no machining or adaptation required to the nozzle bore or fuel line fittings.
- Fits PT2H Trash Pumps — Compatible with PT2H series self-priming centrifugal trash pumps; verify your machine number (5000009094 or 5000009097) before ordering.
- Restores Clean Engine Start-Up — A worn or clogged nozzle causes hard starts, rough idling, and black smoke; replacing it with part 5100017220 restores clean ignition and smooth throttle response.
- Fuel System Integrity — A correctly functioning injection nozzle prevents unburned fuel from washing cylinder walls, protecting downstream engine components from accelerated wear.
The injection nozzle is a precision fuel system component responsible for atomizing diesel fuel into a fine mist before it enters the combustion chamber. The quality of atomization directly controls how completely the fuel burns — a correctly functioning nozzle produces a consistent spray pattern that supports efficient ignition, full power output, and clean exhaust. When an injection nozzle becomes worn, clogged, or begins to dribble rather than spray, the engine suffers from hard starts, loss of power, excessive fuel consumption, and increased exhaust smoke. Replacing a faulty nozzle promptly protects the engine from the downstream effects of poor combustion, including carbon buildup and cylinder wear.
