Lock Washer

The Wacker Neuson Lockwasher is a genuine OEM fastening component designed for an extensive range of Wacker Neuson compaction equipment, including RD tandem rollers, RT and RTL trench rollers, VP and WP vibratory plate compactors, BPU and DPU reversible vibratory plates, and BS vibratory rammers. As a direct OEM replacement, part number is manufactured to the same specification as the original hardware installed at the factory. This Lockwasher fits across a broad cross-section of the Wacker Neuson compaction lineup, making it a practical stock item for dealers, rental fleets, and high-volume service operations. Confirm your model number against the fitment list before ordering to ensure an exact match.

Key Features

• Genuine OEM Material Spec — Manufactured to the same hardness and surface treatment as the original, ensuring correct clamping load and resistance to loosening under vibration.
• Vibration-Resistant Locking Action — Designed specifically for equipment subject to continuous vibration; maintains bolt preload where standard flat washers would allow fasteners to back out over time.
• Direct Drop-In Replacement — Matches the original hole diameter, outer diameter, and thickness so it seats correctly without modification on supported models.
• Wide Cross-Family Fitment — Compatible with RD tandem rollers, RT and RTL trench rollers, VP and WP vibratory plates, BPU and DPU reversible plates, and BS rammers — covering a large portion of the Wacker Neuson compaction equipment range.
• Prevents Costly Fastener Failures — A failed or missing lockwasher can allow critical bolted joints to loosen during operation, leading to structural misalignment or component damage; replacing worn hardware at service intervals is low-cost insurance against larger repairs.

A lockwasher is a hardened fastener component placed under a bolt or nut to resist loosening caused by vibration and dynamic loading. In compaction equipment — where the entire machine transmits high-frequency vibration through its frame, drum, and baseplate assemblies — fasteners are under constant cyclic stress that can cause standard hardware to work loose over time. The lockwasher achieves this by biting into the bearing surface of the fastener and the mating component, creating mechanical resistance to rotation. When a lockwasher is worn, deformed, or missing, the associated bolt or nut can back out during operation, potentially causing misalignment, noise, accelerated wear on adjacent components, or sudden mechanical failure of the joint it was securing.
