Key Features
- OEM Tooth Geometry and Hardness — Manufactured to the original Wacker Neuson material specification, ensuring the toothed profile bites and holds under vibration the same way the factory-installed washer does.
- Drop-In Hardware Replacement — Matches the original bore diameter, outer profile, and tooth count so it seats correctly against mating fasteners without modification.
- Broad LTN Series Coverage — Compatible with LTN4Y, LTN4Y 60 Hz, LTN4Y 120V/60Hz, LTN4Y SA, LTN4Y RH, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk light tower models.
- Vibration Resistance Where It Counts — The toothed design mechanically resists fastener back-off caused by engine and generator vibration, helping bolted connections stay torqued through extended run cycles.
- Genuine OEM Part — Sold as a verified Wacker Neuson OEM component under part number 5100007315, so you can order with confidence that the part matches the assembly it came from.
A toothed lock washer is a hardened fastener component placed between a bolt head or nut and the mating surface. Its serrated teeth bite into both surfaces when the fastener is tightened, creating a mechanical grip that resists loosening from vibration, thermal cycling, and load shifts — conditions that are common in portable light tower applications running on generator power. When a lock washer becomes flattened, corroded, or missing, the fastener it supports can work loose over time, leading to misaligned components or connections that may require more extensive service to correct.
