Wacker Neuson 5000013601 Spring Washer

The Wacker Neuson Spring Washer is a genuine OEM component designed for an exceptionally wide range of Wacker Neuson equipment, including DPU-series reversible vibratory plate compactors, RD7, RD10, RD15, RD25 tandem rollers, PT2H and PT3H trash pumps, HSH350 hydronic surface heaters, G-series portable generators, the DS70 diesel rammer, and the DFS 90 floor saw. As a direct Wacker Neuson OEM part, the is produced to the exact material and dimensional specification used in original assembly — ensuring correct spring tension, seating geometry, and corrosion resistance. This spring washer ships as a single unit and is a straightforward fastener-level replacement that installs without special tooling.

Key Features

• OEM Spring Tension Integrity — Manufactured to the original helical spring-washer specification, delivering the correct preload and lock retention for each application across the fitment range.
• Direct-Fit Fastener Replacement — Matches the exact bore diameter, outside diameter, and coil thickness of the original, seating cleanly under the mating fastener head without shimming or adjustment.
• Broad Cross-Equipment Compatibility — A single stocked part covers DPU reversible vibratory plates, RD tandem rollers, PT2H/PT3H trash pumps, G-series generators, DS70 diesel rammer, HSH350 hydronic surface heater, DFS 90 floor saw, and more.
• Prevents Fastener Back-Out — The spring washer bites into the mating surface under vibration-heavy operating conditions, maintaining clamp load and preventing critical fasteners from loosening during compaction, pumping, or power generation cycles.
• Corrosion-Resistant Material Grade — Manufactured from hardened spring steel suited to outdoor and wet-environment use, consistent with the demanding conditions these machines operate in.

A spring washer is a split or helical ring placed beneath a bolt or nut to maintain clamping force in assemblies exposed to vibration, shock loads, or thermal cycling. As the fastener is tightened, the washer compresses flat, storing elastic energy that continuously pushes back against the nut or bolt head — resisting the gradual loosening that vibration would otherwise cause. In heavy-duty equipment like vibratory plate compactors and tandem rollers, where the entire machine is engineered to transmit high-frequency vibration into the ground, a spring washer at every critical joint is essential to structural integrity. When a spring washer fatigues, loses its set, or is omitted entirely, fasteners can back out during operation, leading to component misalignment, accelerated wear at the joint, or outright failure of the assembly it was securing.
