Wacker Neuson 5000151456 Lock Washer

The Wacker Neuson is a genuine OEM Lock Washer designed for a broad range of Wacker Neuson equipment, including DPU reversible vibratory plate compactors, RD7 tandem rollers, PT2H and PT3H trash pumps, HSH350 hydronic surface heaters, and DS70 diesel rammers. As a direct genuine OEM replacement, this Lock Washer is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct and consistent fit across every compatible model. With fitment spanning dozens of DPU series configurations — including DPU2540H, DPU3050H, DPU4545H, DPU5545H, DPU6555H, and DPU6275H variants — as well as RD7H and RD7He tandem rollers and PT-series trash pumps, part number is a high-demand service item that supports a wide cross-section of the Wacker Neuson fleet.

Key Features

• Genuine OEM Hardware Integrity — Manufactured to Wacker Neuson's original material and dimensional standards, delivering the correct tension and bite needed to keep fastened assemblies secure under vibration-heavy operating conditions.
• Drop-In Replacement — Matches the original Lock Washer profile exactly, seating correctly against mating fasteners and surfaces without rework or shimming.
• Wide Cross-Model Fitment — Compatible with DPU reversible vibratory plates (2540H through 6555H series), RD7H and RD7He tandem rollers, PT2H and PT3H trash pumps, HSH350 hydronic surface heaters, DS70 diesel rammers, and DPS single-direction vibratory plates.
• Vibration Resistance — A correctly functioning lock washer prevents fastener back-off caused by continuous machine vibration; a worn or missing washer can allow critical fasteners to loosen, leading to component misalignment or premature wear.
• Fastener Safety in High-Cycle Applications — On vibratory compaction and pumping equipment that endures constant cyclic loading, maintaining proper fastener preload is essential to safe, consistent operation; this OEM washer helps preserve that preload over the service interval.

A lock washer is a thin hardened ring installed beneath a nut or bolt head to resist loosening caused by vibration and dynamic loads. It works by maintaining clamping force between fastened components — the spring tension or serrated bite of the washer creates friction that prevents the fastener from backing off during operation. On high-vibration equipment such as vibratory plate compactors, tandem rollers, and trash pumps, even minor fastener loosening can lead to component movement, accelerated wear, or structural failure at a joint. Replacing worn or deformed lock washers as part of routine service is a straightforward way to protect the integrity of critical assemblies throughout the machine.
