The Wacker Neuson Lock Washer is a genuine OEM component designed for LTN4Y and LTN5Y series light towers, including variants such as the LTN5Yp, LTN5Ypa, LTN5Yp HD, LTN4Y RH, LTN4Y SA, LTN4Y ME, LTN4Y 60 Hz, and LTN4Y 120V/60Hz. Sourced directly from Wacker Neuson, this is an authorized OEM part — manufactured to the same standards as the original installed in your machine. Fitment spans the full LTN4Y and LTN5Y model range, making it a dependable stock item for fleets running multiple configurations of these light towers. When it is time to service or reassemble, using the correct lock washer ensures fasteners stay properly torqued and secure through extended operation.
Key Features
- OEM Holding Integrity — Manufactured to Wacker Neuson's original specification, this lock washer delivers the correct spring tension and bite needed to resist fastener loosening under vibration.
- Drop-In Replacement — Matches the original in profile, inside diameter, and thickness, so it seats correctly without modification during reassembly.
- Broad LTN Series Fitment — Compatible with LTN4Y and LTN5Y series light towers across multiple regional and voltage configurations, including 60 Hz, 120V/60Hz, SA, ME, RH, HD, CH, and UK variants.
- Vibration Resistance — A functioning lock washer keeps critical fasteners tight during the continuous engine vibration typical of towable light tower operation; a missing or worn washer can allow bolts to back out and cause component damage.
- Genuine Wacker Neuson Part — Part number 5100007319 is an authorized OEM component, ensuring correct material grade and dimensional accuracy for long service life.
A lock washer is a small but essential hardware component placed beneath a nut or bolt head to prevent the fastener from loosening over time. It works by creating friction and mechanical resistance against rotational movement caused by engine vibration, thermal cycling, and operational loads. When a lock washer wears flat, cracks, or goes missing entirely, fasteners can gradually back out, leading to loose assemblies, misalignment, or more serious mechanical failures that require extensive repair.
