Wacker Neuson 5000177346 Lock Washer

The Wacker Neuson Lock Washer is a genuine OEM lock washer designed for a wide range of Wacker Neuson light towers, including the LTN6C-P, LTN6L-P, LTW20Z-1, LTW20Z-3, LTW6K, LTW8K, LTN6L, LTN8K, LTN6K, and LTN6C series, as well as select surface heater units including the E1100 and HSH350. As a direct OEM replacement, the is manufactured to the same standards as the original part that left the factory, ensuring correct fit and function without guesswork. It covers both standard and cold-weather Tier 4F-compliant configurations, making it a go-to replacement for fleets running multiple light tower variants.

Key Features

• OEM Hardness and Bite Spec: — Manufactured to the original tensile and hardness ratings that allow this washer to grip and resist loosening under vibration — exactly what the fastener joint demands in mobile equipment applications.
• Drop-In Replacement: — Matches the original 5000177346 in diameter, thickness, and tooth profile, seating correctly on the fastener without adjustment or rework.
• Broad Light Tower Fitment: — Compatible with LTN6C-P, LTN6L-P, LTW20Z-1, LTW20Z-3, LTW6K, LTW8K, LTN6L, LTN8K, LTN6K, LTN6C series light towers, plus E1100 and HSH350 surface heaters — covering both 60 Hz and Tier 4F variants.
• Vibration Resistance That Holds: — A failed or worn lock washer allows fasteners to back out under continuous engine and generator vibration, leading to loose panels, mounting failures, or structural movement — this OEM part maintains the clamping load where it counts.
• Tier 4F and Cold-Weather Compatibility: — Verified for use on cold-weather and custom Tier 4F-compliant configurations, so fleet operators running specialized builds get the same part integrity as standard units.

A lock washer is a small but critical fastener component that sits between a nut or bolt head and the mating surface to prevent the fastener from loosening due to vibration, thermal cycling, or dynamic loading. On light towers and surface heaters — equipment that runs for extended periods under continuous engine vibration — lock washers keep structural and mechanical connections secure throughout the service cycle. When a lock washer loses its spring tension, deforms, or is missing entirely, fasteners can back out gradually, leading to loose assemblies, misalignment, or damage to surrounding components that far exceeds the cost of the washer itself.
