The Wacker Neuson Serrated Lock Washer is a genuine OEM component designed for the RC50, RC70, and RC110 series single drum soil compactors, including CAB, ROPS, DPF, and vibration roller variants. As a factory-sourced part, it meets the exact specifications set by Wacker Neuson for proper fastener retention across this compactor lineup. The covers a wide range of RC-series configurations, from the RC50 and RC50p through to the RC70vo and RC110p, giving you a single verified part number for multiple machine variants. Stocking this washer ensures you have the right component on hand when scheduled maintenance or a fastener service calls for it.
Key Features
- Genuine OEM Tooth Engagement — Sourced directly from Wacker Neuson, this serrated lock washer delivers the precise tooth profile and hardness required to grip mating fastener surfaces without slipping under vibration.
- Drop-In Replacement — Matched to the original hardware specification, this washer seats correctly against existing fastener hardware with no rework or resizing needed.
- Broad RC-Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, and RC110p models across CAB, ROPS, DPF, and US-market configurations.
- Vibration Resistance — The serrated profile bites into bolt and surface contact faces to resist loosening under the sustained vibration loads that soil compactors generate during operation — a standard lock washer cannot provide the same holding force in these conditions.
- Consistent Clamping Load — A properly functioning serrated lock washer maintains fastener preload over time; a worn or missing washer allows fasteners to back off, leading to component movement, noise, and accelerated wear at the joint.
A serrated lock washer is a hardened fastener component positioned between a bolt head or nut and the mating surface it clamps against. The serrated teeth bite into both contact faces when the fastener is torqued down, creating a mechanical lock that resists rotation and loosening caused by vibration or dynamic loads. On soil compactors like the RC50, RC70, and RC110 series, where continuous vibration is inherent to the machine's compaction work, serrated lock washers play a critical role in keeping structural and mechanical fasteners securely seated. When a washer is lost, damaged, or omitted, fasteners can gradually back out, resulting in loose assemblies, increased wear, and potential component failure if left unaddressed.
