The Wacker Neuson 5100012969 is a genuine OEM Locking Washer designed for a broad range of RD series tandem rollers and RC series single-drum soil compactors. As an authentic Wacker Neuson replacement part, 5100012969 is manufactured to the same specifications as the original hardware, ensuring a direct, correct fit across every compatible machine. This Locking Washer services an extensive lineup including RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers as well as RC50, RC70, and RC110 single-drum soil compactors in their various configurations — including cab, ROPS, DPF, and electric variants. Stocking this part eliminates guesswork and keeps your compaction equipment running without unscheduled interruptions.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to Wacker Neuson's original material and dimensional standards, this Locking Washer delivers the clamping retention and torque resistance the fastener joint was engineered to handle.
- Direct-Install Replacement — Matches the original hole diameter, outer diameter, and tab or tooth profile exactly, so installation follows the same procedure as the factory assembly with no modification to surrounding hardware.
- Broad RD and RC Series Coverage — A single part number covers RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers plus RC50, RC70, and RC110 single-drum soil compactors across cab, ROPS, DPF, open, and electric variants.
- Fastener Joint Security — A properly functioning Locking Washer prevents fastener back-out under vibration loads. On high-cycle compaction machines, loosened hardware can cause misalignment, component damage, and unplanned teardowns.
- Genuine Part Number Traceability — Sourced directly through the Wacker Neuson OEM supply chain, part number 5100012969 carries full traceability, supporting service record accuracy across your fleet.
A locking washer is a hardened fastening component placed beneath a nut or bolt head to resist rotational loosening caused by vibration, shock loads, or thermal cycling. On compaction rollers — machines that generate sustained, high-frequency vibration by design — fastener retention is critical throughout the drivetrain, drum, frame, and hydraulic mounting points. When a locking washer fails or is omitted, the associated fastener can progressively back out, leading to joint movement, component wear, and potential structural failure. Replacing worn or damaged locking washers with the correct OEM part during routine service or repair is essential to maintaining the structural integrity of the machine.
