The Wacker Neuson Washer 0.25 is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers. Sourced directly from Wacker Neuson, this washer matches the exact specifications of the original part, ensuring a correct, trouble-free installation. Verified fitment covers a wide range of LTN4Y and LTN5Y variants, including the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN5Y, LTN5Yp, LTN5Yp HD, LTN5Ypk, LTN5Ypa, LTN5Y CH, LTN5Y UK, and LTN5Y SA models.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, so this washer seats flush and distributes load correctly without shimming or adjustment.
- Direct Drop-In Replacement — Shares the identical bore, outer diameter, and thickness profile as the factory-installed washer, slotting straight into position during assembly or service.
- Broad LTN Series Coverage — A single part number supports the full LTN4Y and LTN5Y family, including 60 Hz, SA, RH, HD, and CH regional variants, simplifying parts ordering for mixed fleets.
- Consistent Clamping Force — A correctly sized washer maintains even fastener load distribution; an undersized or worn washer can allow fasteners to loosen under vibration, leading to hardware damage over time.
- OEM Traceability — Carries Wacker Neuson part number 5100075842, making reordering straightforward and confirming authenticity at the point of installation.
A washer acts as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. By distributing the clamping force over a wider area, it prevents the fastener from pulling through or damaging softer materials and helps maintain consistent tension during operation. On equipment subject to vibration, like a light tower running a generator set, correctly specified washers are essential to keeping fastened assemblies tight and secure over extended run times. When a washer is missing, deformed, or the wrong size, fasteners can work loose or cause surface damage that makes future service more difficult.
