Key Features
- Genuine OEM Locking Integrity — Manufactured to the same hardness and dimensional tolerances as the original, ensuring consistent clamp load and vibration resistance in service.
- Direct Drop-In Replacement — The M18 sizing matches the original bolt specification, so the washer seats correctly against the mating surface without rework or shimming.
- Confirmed Fitment for LTW20Z Series — Verified for LTW20Z-1 and LTW20Z-3 Isuzu T4i light towers, including both 60 Hz and multi-frequency configurations.
- Prevents Fastener Loosening Under Load — Lock washers are the last line of defense against fastener back-off caused by vibration; a worn or missing washer can lead to joint movement and structural loosening.
- Backed by Wacker Neuson OEM Supply — Genuine part number 5000180156 is sourced through the authorized Wacker Neuson parts network, so you receive an unmodified, factory-correct component.
A lock washer is a hardened fastening component placed beneath a nut or bolt head to resist loosening caused by vibration and dynamic loads. In light tower applications, where engine vibration and transport movement are constant, a properly functioning lock washer maintains fastener preload and keeps critical joints secure. When a lock washer is worn flat, deformed, or missing entirely, fasteners can gradually back off — leading to loose assemblies, component misalignment, or, in worst cases, structural failure at the joint.
