The Wacker Neuson 5200020003 is a genuine OEM Camshaft Complete designed for the APT4S and APT4T pump series. As a direct OEM replacement, this camshaft is manufactured to the same specifications as the original component, ensuring correct fit and function across the full range of APT4S and APT4T configurations — including cold weather, surge brake, and electric brake variants. Whether you are servicing an APT4S Pump with Skid or an APT4T Pump with Electric Brake, part number 5200020003 is the correct factory replacement for your application.
Key Features
- OEM-Grade Cam Profile Accuracy — Manufactured to the original lobe geometry and timing specifications, ensuring valve lift and duration match the engine's designed performance envelope.
- Drop-In Fitment for APT4S and APT4T Series — Engineered to install directly into all APT4S and APT4T pump configurations, including cold weather, surge brake, and electric brake variants, with no modification to the engine block or valve train.
- Broad Model Coverage — A single part covers the complete APT4S and APT4T pump family, making it the go-to camshaft replacement for fleets running multiple configurations of these units.
- Sustained Engine Timing Integrity — A correctly functioning camshaft maintains precise valve timing, which directly supports stable pump output and consistent engine power delivery across demanding pumping cycles.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this component carries full OEM traceability and is the same part installed on the production line.
The camshaft is a core engine component responsible for controlling the opening and closing of the intake and exhaust valves in precise coordination with the piston cycle. It translates rotational motion from the crankshaft into the timed valve actuation the engine needs to draw in air-fuel mixture and expel exhaust gases efficiently. When a camshaft wears or fails — through lobe wear, bearing surface damage, or journal scoring — valve timing degrades, leading to loss of engine power, rough running, increased fuel consumption, and potential engine damage if left unaddressed.
