Key Features

• Genuine OEM Hardware Specification — Manufactured to the precise dimensional and material standard of the original cotter pin used on Wacker Neuson light tower assemblies, ensuring correct pin diameter, leg spread, and retention force.
• Drop-In Replacement — Installs directly into the existing clevis or pivot pin bore without any rework; the Less 5/16 designation matches the original hole and pin sizing on the machine.
• Broad Light Tower Compatibility — Fits LT4K, LTP4K, LT4Z, LTP4Z, LTW4Z, LTWP4Z, LTW4K, LTWP4K, LTW6Z, LT4SK, LTP4SK, LT4SZ, and LTP4SZ light tower models, covering both standard and propane-ready variants across multiple production series.
• Retains Critical Pivot and Linkage Connections — A cotter pin in proper condition locks clevis pins, mast linkage pins, and leveling leg hardware securely in place; a missing or bent pin allows components to back out during transport or operation.
• Safety-Critical Fastener — On light tower mast and outrigger assemblies, cotter pins are the last line of retention for load-bearing pivot hardware; using the correctly sized OEM pin is essential for safe mast raising and positioning.

A cotter pin is a simple split-fastener that passes through a drilled hole in a clevis or shaft pin and is then bent open to lock the assembly together, preventing the pin from working loose under vibration or dynamic loads. On Wacker Neuson light towers, cotter pins secure pivot points along the mast, lift linkage, and outrigger leveling legs — connection points that experience repeated movement every time the tower is set up or broken down. When a cotter pin is absent, deformed, or the wrong size, the parent pin it retains can migrate out of its bore, causing unwanted play in the joint or, in a worst case, a sudden disassembly of a load-bearing connection during mast extension.
