Wacker Neuson 5100023873 Toothed Lock Washer

The Wacker Neuson Toothed Lock Washer is a genuine OEM component designed for RC50, RC50p, RC70, RC70p, and RC70VO single drum soil compactors. Sourced directly through Wacker Neuson's authorized parts program, this is the same toothed lock washer fitted at the factory — ensuring a correct, like-for-like replacement every time. Part number covers an extensive range of RC-series configurations including CAB, ROPS, DPF, and US-spec variants, so you can order with confidence knowing fitment is confirmed across the full model family.

Key Features

• Genuine OEM Locking Integrity — Manufactured to Wacker Neuson's original tooth profile and hardness spec, so the washer bites and holds with the same retention force as the part it replaces.
• Drop-In Replacement — Matches the original hole diameter, outer dimensions, and tooth geometry for direct installation with no fitting adjustments needed.
• Broad RC-Series Coverage — Confirmed fitment across RC50, RC50p, RC70, RC70p, and RC70VO variants, including CAB, ROPS, DPF, and US-spec configurations.
• Prevents Fastener Back-Out — The toothed profile bites into mating surfaces under vibration-heavy compaction cycles, keeping critical fasteners from loosening during operation.
• Verified Part Number — Order by Wacker Neuson part number 5100023873 for exact catalog accuracy — eliminates guesswork when cross-referencing against multiple machine serial number ranges.

A toothed lock washer is a hardened fastener component placed beneath a bolt or nut to prevent loosening caused by vibration, torque, or cyclical loading. The serrated teeth deform slightly as the fastener is torqued down, biting into both the mating surface and the underside of the fastener head to create a mechanical lock. On soil compactors like the RC50 and RC70 series, where the drum generates continuous vibration during compaction passes, a worn or missing lock washer can allow fasteners to back out gradually — leading to component movement, accelerated wear on adjacent parts, or structural fastener failure if left unaddressed. Replacing a damaged or missing toothed lock washer promptly is a straightforward step that protects the integrity of the broader assembly it secures.
