The Wacker Neuson 5200020005 is a genuine OEM Camshaft Gear designed for the APT4T and APT4S series self-priming trash pumps. As a factory-sourced component, it is manufactured to the exact tolerances required by the original engine design, ensuring proper valve timing and consistent pump performance across all covered variants. Fitment is confirmed for APT4T Surge Brake, APT4T Electric Brake, APT4T Cold Weather, APT4S with Skid, and APT4S Cold Weather configurations. When a camshaft gear wears or fails, valve timing is disrupted, leading to rough running, power loss, or complete failure to start — making prompt replacement with the correct part essential.
Key Features
- OEM Gear Accuracy: — Manufactured to precise tooth profile and pitch specifications so valve timing stays synchronized with the crankshaft under continuous pump load.
- Direct Engine Drop-In: — Matches the original gear mounting and mesh geometry for the APT4T and APT4S engine assemblies, allowing straightforward installation without modification.
- Broad APT4T and APT4S Coverage: — A single part number covers Surge Brake, Electric Brake, Cold Weather, and Skid-mounted pump variants, simplifying parts sourcing across your fleet.
- Sustained Valve Timing Integrity: — Correct camshaft gear engagement keeps intake and exhaust valves opening and closing at the right moment, preserving engine power output and fuel efficiency throughout the pump's service life.
- Genuine Wacker Neuson Part: — Supplied as a genuine OEM component, this gear is sourced directly through the Wacker Neuson parts network, ensuring it meets the same production standards as the original equipment.
The camshaft gear is a core timing component in the pump's engine, responsible for driving the camshaft in sync with the crankshaft. This synchronization controls when the intake and exhaust valves open and close during each combustion cycle — if the gear wears, chips, or loses mesh, valve timing shifts and engine performance deteriorates rapidly. On trash pumps like the APT4T and APT4S, which operate under sustained load moving water, debris, and slurry, a worn camshaft gear can cause hard starting, misfiring, or complete engine shutdown. Replacing the gear at the first sign of noise or timing irregularity protects the broader valve train and keeps the pump running at full capacity.
