The Wacker Neuson 5100039757 is a genuine OEM Cotter Pin designed for a wide range of Wacker Neuson portable generators and light towers, including the G25, G50, and G70 skid-mounted mobile generator series as well as the LTN6C, LTN6L, LTN6K, LTN8K, LTV6K, LTV6L, LTV8K, and MGT trailer series. Sourced directly from Wacker Neuson, this cotter pin meets the same specifications as the original hardware installed at the factory. Exact part number match is critical with fasteners of this type — always verify your model number and machine number before ordering to confirm fitment.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same material and dimensional specification as the original cotter pin, ensuring correct retention force and shear resistance in service.
- Drop-In Installation — Installs directly into the existing clevis pin or shaft bore without rework, maintaining the original fastening geometry of the assembly.
- Broad Generator and Light Tower Coverage — Fits G25, G50, and G70 skid-mounted mobile generators across standard, cold weather, extended run, and custom configurations, plus the LTN6C, LTN6L, LTN6K, LTN8K, LTV6K, LTV6L, LTV8K light tower families and MGT trailer variants.
- Critical Retention Function — A cotter pin in failed or missing condition allows linked or pinned components to shift or disengage under vibration; replacing a worn pin restores the positive locking action the assembly depends on.
- Low-Cost Preventive Hardware — Cotter pins are inspected and replaced during routine service intervals; having the correct OEM part on hand keeps scheduled maintenance on track.
A cotter pin is a small split-pin fastener inserted through a drilled hole in a shaft or clevis pin and then bent open to lock a component in place, preventing axial movement or accidental disassembly. On generators and light towers, cotter pins are typically found securing linkage pins, hitch connections, leveling leg assemblies, and other mechanical joints that are subject to vibration during transport and operation. When a cotter pin is missing, broken, or badly corroded, the pinned connection it secures can work loose, leading to misalignment, component wear, or an unsafe condition. Regular inspection and timely replacement with a correctly sized pin is a straightforward way to maintain the mechanical integrity of these assemblies.
