The Wacker Neuson is a genuine OEM Spring Washer designed for the LTN4Y and LTN5Y series light towers, including LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this genuine OEM part is manufactured to the same specification as the original component installed at the factory. Keeping the correct spring washer in place is essential for maintaining proper clamp load and fastener integrity across the assembly. If you are servicing any of the LTN4Y or LTN5Y series machines, part number is the correct direct replacement to restore original performance.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the original spring-rate and material hardness specification, ensuring consistent clamp load and resistance to loosening under vibration.
- Direct Drop-In Replacement — Matches the original dimensional profile exactly, seating correctly on the fastener without adjustment or rework during reassembly.
- Broad LTN Series Compatibility — Fits LTN4Y and LTN5Y series light towers across multiple voltage configurations, including SA, CH, UK, RH, 60 Hz, and 120V/60Hz variants.
- Vibration Resistance — Spring washers are critical in light tower applications where engine and generator vibration can cause fasteners to back off over time; a worn or fatigued washer loses its preload and allows fastener movement.
- Authorized Wacker Neuson Part — Carries the full backing of Wacker Neuson's genuine parts program, so you can be confident in the part's origin and quality pedigree.
A spring washer is a small but mechanically important fastener component that sits beneath a nut or bolt head to maintain tension in a bolted joint. Its slightly dished or coiled form stores elastic energy that keeps constant pressure on the fastener, resisting loosening caused by vibration, thermal cycling, or dynamic loads — all conditions common in light tower operation. When a spring washer loses its temper, becomes flattened, or fractures, the fastener it supports can work loose, potentially leading to component misalignment, accelerated wear, or fastener failure in the assembly.
