Wacker Neuson 5100013536 Serrated Lock Washer

The Wacker Neuson Serrated Lock Washer is a genuine OEM component designed for a broad range of Wacker Neuson tandem rollers and single drum soil compactors, including the RD18, RD24, RD28, RD40, RD45 tandem roller series and the RC50, RC70, and RC110 single drum soil compactor series. As a direct factory replacement, part is manufactured to the exact material and dimensional specifications required for proper function in these machines. This serrated lock washer ships as a genuine Wacker Neuson part, so you can be confident it will seat and perform exactly as the original did. Cross-reference your model number against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Material Integrity — Manufactured from hardened steel with precision-formed serrations that bite and hold under torque load, maintaining secure fastener tension in high-vibration compaction equipment.
• Drop-In Installation — Matches the original washer's bore, outer diameter, and serration profile exactly, seating onto existing hardware without modification.
• Wide Model Coverage — Fits RD18, RD24, RD28, RD40, and RD45 tandem roller variants as well as RC50, RC70, and RC110 single drum soil compactor series, including C, O, DPF, and VO configurations.
• Vibration Resistance — The serrated locking profile resists bolt loosening caused by the constant vibration generated during compaction cycles, preserving clamping force over extended service intervals.
• Verified Wacker Neuson Part Number — Sourced directly from Wacker Neuson, part number 5100013536 is the correct OEM reference for this application — eliminating guesswork when ordering replacement hardware.

A serrated lock washer is a hardened fastening component placed beneath a nut or bolt head to prevent loosening under vibration and dynamic loads. The serrated edges bite into both the fastener face and the mating surface, creating mechanical resistance that maintains clamping force even as a machine vibrates during operation — exactly the conditions present in compaction rollers and soil compactors. When a lock washer wears flat, loses its temper, or is omitted entirely, fasteners can work loose over time, leading to structural movement, component misalignment, or accelerated wear on surrounding parts.
