The Wacker Neuson Spring Washer M16 is a genuine OEM component designed for PSC-series submersible pumps, including the PSC42203, PSC43703, PSC42303EX, and PSC43803EX. As a factory-sourced part, the meets the exact material and dimensional standards set by Wacker Neuson for these pump models, ensuring correct load distribution and fastener retention on assembly. Sourcing the correct spring washer is critical in pump applications where vibration and continuous operation can cause fastener loosening over time.
Key Features
- Genuine OEM Spring Tension: — Manufactured to Wacker Neuson's original material spec, delivering the correct deflection and locking force for M16 fasteners in submersible pump assemblies.
- Direct Bolt-Pattern Fitment: — Sized specifically for M16 hardware, this washer drops straight into place without shimming or modification during reassembly.
- Confirmed PSC-Series Compatibility: — Verified for the PSC42203, PSC43703, PSC42303EX, and PSC43803EX submersible pump models.
- Vibration and Loosening Resistance: — The spring profile maintains continuous clamp load under the sustained vibration common in pump operation, helping fasteners stay seated through extended run cycles.
- Corrosion-Resistant Construction: — Built to withstand the wet, submerged environments these pumps operate in, supporting long service intervals without premature degradation.
A spring washer works by using its curved or split profile to apply continuous outward pressure against a fastener and the mating surface it secures. This spring tension compensates for the micro-movement and vibration that occurs during machine operation, preventing nuts and bolts from backing out over time. In submersible pump assemblies, where components are subject to both mechanical vibration and constant water exposure, a worn or missing spring washer can allow critical fasteners to loosen, leading to leaks, misalignment, or component failure. Using the correct OEM-spec replacement — part 5000177073 — ensures the fastener stack performs exactly as Wacker Neuson designed it.
