The Wacker Neuson Lock Washer 16 is a genuine OEM component designed for the DPS1850H (Asphalt, Basic, and Vario variants), DPS1850Y vibratory plate compactors, and the DFS 90 powered floor saw. As a direct factory replacement, this lock washer installs exactly as the original, requiring no modification to surrounding hardware. Confirmed fitment spans the full DPS1850H series — including multiple machine configurations across this model family — as well as the DPS1850Y and DFS 90, making it a versatile service part to keep on hand. Order by part number to ensure you receive the correct specification for your machine.
Key Features
- Genuine OEM Specification: Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring the locking engagement matches what the fastener assembly was engineered for.
- Direct Hardware Replacement: Sized at 16mm to seat correctly against the mating fastener without shimming or substitution — drops straight in during reassembly.
- Broad Model Coverage: Confirmed fitment across the DPS1850H Asphalt, Basic, and Vario configurations, the DPS1850Y vibratory plate, and the DFS 90 powered floor saw.
- Prevents Fastener Back-Off: A functioning lock washer maintains clamp load under vibration; a worn or omitted washer allows fasteners to loosen progressively during operation, leading to component misalignment or damage.
- Critical for High-Vibration Applications: Vibratory plate compactors and floor saws subject every fastened joint to continuous cyclical force — using the correct OEM lock washer at each service point is essential to maintaining structural integrity over operating hours.
A lock washer is a hardened fastener component installed beneath a nut or bolt head to resist rotational loosening caused by vibration and dynamic loading. In equipment like vibratory plate compactors and floor saws, where the entire machine frame is subject to sustained vibration, lock washers play a key role in keeping critical assemblies torqued and secure. When a lock washer becomes flattened, cracked, or missing, the fastener it supports can back out over time, creating play in the assembly and potentially causing accelerated wear or component failure.
