The Wacker Neuson Crankcase Cover is a genuine OEM component designed for MDP3 series trash pumps. Sourced directly from Wacker Neuson, this part is manufactured to the same standards as the original, ensuring a correct, hassle-free installation on your machine. Compatible with multiple MDP3 trash pump configurations, including the MDP3 Trash Pump models, this cover is the right choice when you need a part you can trust. Keep your pump running the way it left the factory by specifying the correct OEM part number every time.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original tolerances, this crankcase cover maintains the critical oil-tight seal that protects internal engine components from contamination and leakage.
- Direct-Fit Replacement — Engineered to match the original mounting points and gasket mating surfaces of MDP3 series pumps, so it installs cleanly without rework or modification.
- Broad MDP3 Series Compatibility — Fits multiple MDP3 trash pump variants, including standard and dimensional-spec models (L593, W440, H442), covering a wide range of MDP3 configurations.
- Engine Protection Restored — A failed or cracked crankcase cover exposes engine internals to dirt, moisture, and oil loss. Replacing it promptly restores proper crankcase pressure and lubricant containment.
- Verified Part Number — Part number 5000406843 is the correct OEM reference for this application, taking the guesswork out of sourcing and reducing the risk of ordering an incompatible cover.
The crankcase cover seals the engine's crankcase cavity, keeping engine oil contained and preventing contaminants such as dirt and water from entering the rotating assembly. It also plays a role in maintaining proper crankcase pressure, which is essential for consistent lubrication and efficient engine operation. When the cover cracks, warps, or loses its seal, oil leaks and internal contamination can follow — leading to accelerated engine wear and potential pump failure if not addressed.
