Wacker Neuson 5000151427 Spring Washer

The Wacker Neuson is a genuine OEM Spring Washer designed for a wide range of Wacker Neuson equipment, including DPU series reversible vibratory plate compactors, PT2H and PT3H self-priming centrifugal trash pumps, the HSH350 hydronic surface heater, DS70 diesel rammer, and E1100 ground heater. As a direct genuine OEM replacement, this Spring Washer is produced to the exact material and dimensional specifications used in original factory assembly, ensuring consistent performance across every compatible machine in the lineup. With fitment spanning the DPU 2540H through the DPU 6275 series — along with DPS1850H, DPS2050H, DPS3060H variants, and multiple PT2H and PT3H pump configurations — this is a high-utility hardware component stocked by professional service technicians and fleet maintenance crews alike. Keep a quantity on hand and eliminate unnecessary delays during routine service or field repairs.

Key Features

• Genuine OEM Spring Tension Integrity — Manufactured to Wacker Neuson's exact material hardness and spring-rate spec, so the washer delivers consistent clamping load and vibration resistance across every fastened joint.
• Drop-In Hardware Replacement — Matches the original bore diameter, outside diameter, and thickness of the factory-installed washer, allowing direct installation without filing, shimming, or modification.
• Broad Cross-Equipment Compatibility — A single part number covers DPU 2540H–6275 reversible plate compactors, DPS1850H/2050H/3060H asphalt plates, PT2H/PT3H trash pumps, the HSH350 hydronic surface heater, the DS70 diesel rammer, and E1100 ground heaters.
• Prevents Fastener Loosening Under Vibration — Spring washers are specifically engineered to resist self-loosening in high-vibration environments; using the correct OEM-grade washer maintains joint preload during extended compaction or pump operation.
• Verified Wacker Neuson Part Number — Ordered and catalogued under part number 5000151427, so dealers, technicians, and parts managers can cross-reference and confirm fitment with confidence before ordering.

A spring washer is a hardened, split-ring fastener component placed beneath a bolt or nut to maintain clamping force in assemblies that are subject to vibration, thermal cycling, or dynamic loading. The slight angular gap in the washer acts as a mechanical spring — as the fastener is torqued down, the washer flattens and exerts a continuous outward load that resists loosening over time. In heavy-duty equipment like vibratory plate compactors and trash pumps, fasteners are exposed to constant oscillation and operational stress; a worn, deformed, or missing spring washer allows joints to work loose, leading to component misalignment, fastener failure, and accelerated wear on surrounding hardware. Replacing spring washers as part of routine service is a simple, low-cost step that protects the integrity of the assemblies they secure.
