The Wacker Neuson Oil Pump Cover is a genuine OEM component designed for the GS10003G generator series. Sourced directly from Wacker Neuson, this cover is manufactured to the exact tolerances required for correct oil pump operation and long-term sealing integrity. As a genuine OEM part, it carries the same specifications as the original component installed at the factory, so you can replace it with full confidence in fit and function. If you are servicing a GS10003G unit, part number is the correct, verified replacement.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to exact dimensional tolerances, ensuring the cover seats flush and maintains a proper oil-tight seal against the pump housing.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the original cover, aligning directly with existing mounting points on the oil pump assembly.
- Confirmed Fitment for GS10003G — Verified for the Wacker Neuson GS10003G (No-CE) generator, eliminating compatibility guesswork before you order.
- Protects Oil Pump Function — A correctly fitted cover keeps the pump primed and operating at proper pressure; a cracked or missing cover can lead to oil loss and accelerated pump wear.
- Authorized Wacker Neuson Part — Part number 5000408891 is an official Wacker Neuson component, giving you traceability and confidence in every service job.
The oil pump cover is a protective housing component that encloses and seals the oil pump mechanism within the engine assembly. It maintains the internal pressure environment needed for the pump to draw and circulate oil consistently throughout the engine. When the cover is cracked, warped, or improperly seated, oil pressure can drop and lubrication to critical engine components becomes compromised — leading to accelerated wear or engine damage if left unaddressed.
