The Wacker Neuson 5100012965 is a genuine OEM Locking Washer designed for the RD and RC series of compaction equipment, including tandem rollers and single-drum soil compactors spanning the RD18, RD24, RD27, RD28, RD40, RD45, RC50, RC70, and RC110 model families. As a direct OEM component, part number 5100012965 is manufactured to the exact tolerances required by Wacker Neuson for these machines, ensuring a correct, consistent installation every time. This Locking Washer is stocked to support a wide range of configurations across the RD and RC lineups, including standard, cab, ROPS, DPF, and combination variants. Confirm your model number against the fitment list before ordering to ensure this is the correct part for your machine.
Key Features
- Genuine OEM Manufacture — Produced to Wacker Neuson's exact material and dimensional specification for locking washers used in compaction equipment drivetrains and structural assemblies.
- Drop-In Replacement — Engineered to match the original mounting position and locking geometry, so installation follows the standard service procedure without rework.
- Broad RD and RC Series Coverage — Compatible across RD18, RD24, RD27, RD28, RD40, RD45 tandem roller variants and RC50, RC70, RC110 single-drum soil compactor configurations, including DPF, cab, and ROPS models.
- Maintains Fastener Security — A correctly seated locking washer prevents fastener back-out under the sustained vibration loads generated during compaction passes, protecting the integrity of the joint it secures.
- Sourced Direct from Wacker Neuson — Ordering by OEM part number 5100012965 eliminates the guesswork of cross-referencing aftermarket equivalents for a machine family this large.
A locking washer is a small but critical fastener component positioned between a bolt or nut and the mating surface it clamps. Its purpose is to resist loosening caused by vibration, rotation, or thermal cycling — conditions that are constant on compaction equipment during operation. On tandem rollers and single-drum soil compactors like the RD and RC series, where high-frequency vibration is central to the machine's function, a worn, deformed, or missing locking washer allows fasteners to back out gradually, which can lead to component misalignment, accelerated wear on adjacent parts, or mechanical failure at the secured joint. Replacing a damaged locking washer promptly with the correct OEM part keeps the surrounding assembly secure and operating as designed.
