The Wacker Neuson Pin is a genuine OEM Pin designed for a broad range of Wacker Neuson portable equipment, including ML-series light towers, MG-series portable generators, MDP3 trash pumps, and MPU 29 reversible plates. As a direct OEM replacement, it is manufactured to the same standards as the original part that left the factory, ensuring the correct dimensions and material grade every time. This Pin fits an extensive list of configurations across the ML440, ML425, ML240, ML225, MG5, MG3, MDP3, and MPU 29 model families, making it a versatile stocking part for contractors and service technicians running mixed fleets. Ordering by part number confirms you are sourcing the correct component for your specific machine.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the original Wacker Neuson specification, so the pin seats and retains components with the correct interference and clearance tolerances — no guesswork on fitability.
- Drop-In Installation — Matches the original pin diameter, length, and retention geometry, so it installs directly into existing mounting points without reworking the surrounding components.
- Wide Fleet Coverage — A single part number covers ML440, ML425, ML240, ML225 light towers; MG5 and MG3 portable generators (including sd and d variants); MDP3 trash pumps; and MPU 29 reversible plates — ideal for multi-machine service inventory.
- Structural Integrity Under Load — A correctly fitted pin maintains the alignment and articulation of connected components; a worn or missing pin allows unwanted movement that accelerates wear on adjacent parts and can lead to structural failure under operating loads.
- Verified Part Number — Sourcing by OEM part number 5000403975 eliminates substitution errors and confirms compatibility across all listed model variants and serial number ranges.
A pin is a precision retention and alignment fastener used to secure two or more components in a fixed positional relationship, allowing controlled movement — such as rotation or articulation — while preventing unintended separation. In light towers, generators, pumps, and compaction equipment, pins are typically found at pivot points, linkage connections, and structural joints where repeated dynamic loads are applied. When a pin wears, bends, or goes missing, the connected components lose their correct alignment, causing accelerated wear on bores and brackets, increased vibration, and potential failure of the assembly during operation.
