Wacker Neuson 5100012968 Locking Washer

The Wacker Neuson 5100012968 is a genuine OEM Locking Washer designed for a broad range of Wacker Neuson tandem rollers and single-drum soil compactors across the RD and RC series. This OEM part is sourced directly through the Wacker Neuson parts network, ensuring it meets the exact tolerances and material specifications required for your machine. Fitment spans the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, as well as RC50, RC70, and RC110 single-drum soil compactors in their various configurations including cab, ROPS, DPF, and electric variants. Confirming your model against part number 5100012968 before ordering is always the best practice given the wide range of compatible units.

Key Features

• Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified hardness and temper requirements, ensuring the washer maintains clamping load without deforming or losing its locking ability under operational vibration.
• Drop-In Replacement — Matches the original fastener diameter and seating geometry, so it installs directly onto existing hardware without rework or shimming.
• Wide RD and RC Series Coverage — Compatible across RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers and RC50, RC70, and RC110 single-drum soil compactors, including cab, ROPS, DPF, and electric-drive configurations.
• Maintains Fastener Security — A properly functioning locking washer prevents critical bolted joints from loosening under the continuous vibration these compaction machines generate during operation; a worn or missing washer can allow joint movement that leads to accelerated component wear.
• Fastener Integrity Matters — On compaction equipment subject to constant dynamic loading, using a correctly rated locking washer at critical attachment points is an important element of maintaining structural and mechanical integrity.

A locking washer is placed beneath a nut or bolt head to resist loosening caused by vibration and dynamic loading. On tandem rollers and single-drum soil compactors — machines that generate significant continuous vibration during compaction passes — threaded fasteners at structural, drivetrain, and drum attachment points are especially vulnerable to backing out over time. The locking washer bites into both the mating surface and the fastener, creating mechanical resistance that keeps the joint tight. When a locking washer becomes compressed, corroded, or missing entirely, the fastener it was protecting can work loose, leading to joint movement, accelerated wear on surrounding components, and potential mechanical failure if left unaddressed.
