Wacker Neuson 5000103834 Lock Washer

The Wacker Neuson 5000103834 is a genuine OEM Lock Washer designed for a wide range of Wacker Neuson vibratory plate compactors and gasoline rammers, including BPS, APS, DPS, and BS series machines. As a direct OEM replacement sourced through the Wacker Neuson parts program, this washer is produced to the exact tolerances required for proper fastener retention in these applications. It fits an extensive list of models across the BPS1030, BPS1135, BPS1340, BPS1550, BPS2050, APS1030, APS1135, APS1340, APS1550, APS2050, AP1850e, DPS1850H, DPS2050H, DPS3060Hv, and BS50 through BS70 series. Confirm your machine's model number before ordering to ensure a correct match.

Key Features

• Genuine OEM Locking Integrity — Manufactured to Wacker Neuson's exact hardness and dimensional spec, ensuring the washer provides the correct clamping load and bite against mating fasteners in high-vibration assemblies.
• Drop-In Replacement — Matches the original washer's inner diameter, outer diameter, and tooth profile so it seats correctly on the first install without rework or shimming.
• Broad Model Coverage — A single part number spans the BPS, APS, DPS, and BS plate compactor and rammer families, making it a practical stock item for mixed fleets.
• Vibration-Environment Durability — Lock washers in compaction equipment are subject to continuous shock loading; using the correct OEM-spec washer prevents fastener back-out that can lead to component loosening and unplanned disassembly.
• Fastener System Integrity — A worn or undersized lock washer loses its ability to resist rotation under load; replacing it with part 5000103834 restores the designed clamping force throughout the fastened joint.

A lock washer is a hardened, toothed or split-ring fastener component placed beneath a bolt or nut to resist loosening caused by vibration and dynamic loads. In vibratory plate compactors and rammers, where the entire machine operates through high-frequency mechanical vibration, fastener retention is critical — any joint that backs off can allow components to shift, wear prematurely, or separate entirely. Replacing a fatigued or deformed lock washer with the correct OEM part restores the clamping integrity of the joint and prevents recurring fastener failures.
