The Wacker Neuson is a genuine OEM Lock Washer designed for a broad range of Wacker Neuson reversible vibratory plate compactors and tandem roller equipment. This includes the DPU 2950Y, DPU 4045H, DPU 5045H, DPU 6055, DPS 1850Y, and RD10 series machines, as well as the D4000 diesel power unit for internal vibrators. As a genuine Wacker Neuson part, the is manufactured to the exact specifications of the original component installed at the factory. Sourcing the correct lock washer by verified part number ensures a proper fit across the full range of compatible DPU and RD10 models.
Key Features
- Genuine OEM Material Integrity — Manufactured to the exact hardness and dimensional tolerances required for secure fastener retention under the high-vibration loads generated by reversible vibratory plate compactors and tandem rollers.
- Drop-In Replacement — Matches the original lock washer position and hole sizing, seating directly onto the host fastener without any modification to the mating hardware.
- Wide Model Coverage — Compatible with DPU 2950Y, DPU 4045H, DPU 5045H, DPU 6055, DPS 1850Y, RD10, and D4000 series equipment — one part number spanning multiple machine configurations.
- Vibration-Resistant Locking — Lock washers in compaction and roller equipment are subjected to sustained high-frequency vibration; the correct grade and profile prevent fastener back-out that can lead to loose assemblies and accelerated component wear.
- Verified Part Number — Ordering by confirmed OEM part number 5000033724 eliminates the risk of receiving an incorrectly sized washer that fails to seat or provide adequate clamping load.
A lock washer is a hardened fastening component placed beneath a nut or bolt head to resist loosening caused by vibration, torque, or thermal cycling. In reversible vibratory plate compactors and tandem rollers — machines that generate continuous high-frequency vibration during operation — standard flat washers alone cannot reliably prevent fastener back-out over time. The lock washer creates mechanical resistance through its spring tension or bite edges, maintaining clamp load at the joint. When a lock washer is worn, deformed, or missing, fasteners in critical assemblies can work loose progressively, leading to component misalignment, accelerated wear on surrounding parts, or structural failure at the joint.
