The Wacker Neuson Serrated Lock Washer is a genuine OEM serrated lock washer designed for the RC50, RC50p, RC70, RC70p, RC70vo, RC110 ROPS, and RC110 CAB series single drum soil compactors. Sourced directly from Wacker Neuson, this part carries the same OEM specification as the component installed at the factory, so you can be confident in fit and function from the moment it goes on. It is compatible with both standard and p-series variants across multiple production runs, making it a dependable choice for technicians servicing the full RC-series lineup. Confirm your model and serial number against the fitment list before ordering to ensure this is the correct washer for your machine.
Key Features
- OEM Serration Integrity — Genuine Wacker Neuson manufacture means the serration profile, tooth geometry, and hardness match the original specification exactly, maintaining proper locking force under vibration.
- Drop-In Replacement — Matches the original bore diameter, outer diameter, and thickness so it seats flush against the mating fastener and surface without rework or adjustment.
- Broad RC-Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110 ROPS, and RC110 CAB models, covering both ROPS and cab-equipped configurations across multiple build years.
- Vibration-Resistant Fastener Security — On compaction equipment, constant drum vibration works fasteners loose over time; the serrated locking profile bites into the mating surfaces to resist loosening during operation.
- Genuine OEM Part — Supplied as a genuine Wacker Neuson OEM component, carrying the manufacturer part number 5100075173 for straightforward verification against your parts manual or service documentation.
A serrated lock washer is a hardened fastener component placed beneath a bolt head or nut to prevent the fastener from backing out under load and vibration. The serrated teeth bite into both the fastener bearing surface and the substrate when the fastener is torqued, creating a mechanical resistance that resists loosening even in high-vibration environments like compaction machinery. When a lock washer becomes worn, deformed, or is omitted entirely, fasteners in critical assemblies can gradually back out, leading to loose components, accelerated wear on surrounding hardware, and potential structural failure at the joint.
