The Wacker Neuson Locking Washer is a genuine OEM locking washer designed for the RC110 and RC110p series compactors, including ROPS and CAB configurations. As a factory-sourced component, part is manufactured to the same standards as the original hardware installed at the time of assembly. It is confirmed compatible across the RC110, RC110p, RC110 US ROPS, RC110p US ROPS, RC110 US CAB, and RC110p US CAB model lines, making it the straightforward choice when replacing worn or damaged hardware on these machines.
Key Features
- Genuine OEM Hardware Integrity — Sourced directly from Wacker Neuson, this locking washer meets the exact material hardness and dimensional tolerances specified for the original fastening application.
- Drop-In Fastener Replacement — Matches the original hole diameter, thickness, and locking profile for straightforward installation without rework or shimming.
- Broad RC110 Series Coverage — Fits RC110 and RC110p compactors in ROPS and CAB configurations, covering both standard and US-spec variants.
- Secure Fastener Retention — A correctly functioning locking washer resists loosening under vibration and load cycling — critical on compaction equipment where fastener integrity directly affects structural and operational stability.
- Verified Part Number — Order with confidence using OEM part number 5100063901 to confirm you are receiving the correct washer for your machine configuration.
A locking washer is a hardened fastening component placed beneath a nut or bolt head to prevent the fastener from backing out under repeated vibration, impact, or cyclic loading. On compaction equipment like the RC110 series, where the machine operates under constant vibratory forces, locking washers play a key role in keeping critical fastener assemblies secure over time. When a locking washer becomes deformed, cracked, or loses its tension, the associated fastener can gradually loosen — potentially leading to component misalignment, accelerated wear on surrounding parts, or fastener failure during operation.
