The Wacker Neuson 5100013440 is a genuine OEM Locking Washer designed for a broad range of Wacker Neuson single-drum soil compactors and tandem rollers, including the RC50, RC70, RC110, and RD-series models such as the RD18, RD24, RD27, RD28, RD40, and RD45. As a factory-original component, part 5100013440 is manufactured to the exact tolerances required by these machines, ensuring consistent installation and secure fastener retention. This Locking Washer covers an extensive fitment range spanning both ROPS and CAB configurations as well as DPF-equipped variants across the RC and RD product families. Confirm your machine's model number against the fitment list before ordering to ensure accurate application.
Key Features
- Genuine OEM Torque Retention: — Factory-original locking washer engineered to maintain correct clamp load and prevent fastener back-off under the vibration loads generated by compaction equipment.
- Direct-Fit Installation: — Matches the original hole diameter, thickness, and tooth profile exactly, dropping into place without modification on all listed RC and RD configurations.
- Broad Fitment Coverage: — Compatible with RC50, RC50p, RC70, RC70p, RC70vo, RC110, RC110p single-drum soil compactors and RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers, including ROPS, CAB, DPF, and electric variants.
- Vibration-Resistant Locking Action: — The serrated or spring-style locking geometry resists loosening during continuous drum operation, maintaining structural integrity at fastened joints over extended service intervals.
- Critical Fastener Safety Role: — In compaction equipment, loose fasteners at structural or drivetrain joints can lead to accelerated wear, component damage, or unsafe machine operation; replacing a worn or damaged locking washer restores proper joint security.
A locking washer is a small but mechanically important fastener component placed beneath a nut or bolt head to prevent the fastener from rotating loose under vibration or dynamic loading. In heavy compaction equipment like the RC-series soil compactors and RD-series tandem rollers, the constant vibration generated during operation creates conditions that cause standard fasteners to back off over time. The locking washer's toothed, serrated, or spring profile bites into the mating surface, maintaining clamping force across the joint. When a locking washer is worn flat, cracked, or missing, the fastener it secures can loosen progressively, leading to joint movement, component wear, and potential structural or drivetrain damage if left unaddressed.
