The Wacker Neuson Oil Protector is a genuine OEM component designed for a wide range of Wacker Neuson portable generators, light towers, single direction plates, reversible plates, floor saws, trash pumps, and fire pumps — including the MG3, MG5, MP15, ML440, ML425, ML240, ML225, MPU 29, MDP3, MFS12, MFS14, MFSX14, MD3.5, MP70, MFP1.5, and MFP2 series. As a factory-sourced part, the is manufactured to the exact same specifications as the original component installed at the plant, so it installs correctly the first time without guesswork. Wacker Neuson's broad equipment lineup means this single part number covers an extensive cross-section of machines, making it a smart stock item for dealers and service crews running mixed fleets. Confirm your model and serial number against the fitment list before ordering to ensure this is the correct oil protector for your machine.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring the oil protector compresses and seats correctly to maintain a leak-free barrier.
- Direct-Fit Installation — Engineered to match the original mounting configuration, so the part drops into place with no trimming, shimming, or adapting required.
- Broad Fleet Coverage — A single part number that spans portable generators (MG3, MG5), light towers (ML225, ML240, ML425, ML440), compaction plates (MP15, MP70, MPU 29), floor saws (MFS12, MFS14, MFSX14), trash pumps (MDP3), and fire pumps (MFP1.5, MFP2).
- Oil Containment Assurance — A properly functioning oil protector prevents contamination and unwanted oil migration within the engine or pump assembly, protecting internal components from accelerated wear.
- Sourced from the Manufacturer — Carrying Wacker Neuson's part number 5000404006 directly, this component meets the same quality controls applied to every unit that left the factory — not a third-party interpretation of the spec.
An oil protector functions as a sealing or shielding element that prevents oil from migrating into areas of the machine where it can cause damage, contaminate other fluids, or escape the engine or pump housing entirely. On high-cycle equipment like generators, compaction plates, and pumps, this barrier experiences constant pressure and temperature variation, which gradually degrades its sealing capability over time. When an oil protector fails or is worn, the result is typically visible leaks, oil consumption, and potential damage to surrounding components — making timely replacement an important part of any scheduled service interval.
