The Wacker Neuson Serrated Lockwasher V.8.4 is a genuine OEM component designed for the RD25 Hydrostatic Double Drum Vibratory Roller series. Sourced directly from Wacker Neuson, this lockwasher matches the exact specification of the original part installed at the factory. It is confirmed to fit RD25 models including configurations and, so you can order with confidence that this is the correct part for your machine.
Key Features
- OEM-Grade Serration Integrity — Manufactured to Wacker Neuson's original serration profile, ensuring the washer bites and holds under the vibration loads typical of compaction equipment.
- Drop-In Replacement — Matches the original mounting dimensions and bore size so it seats correctly without rework or adjustment during reassembly.
- Confirmed RD25 Fitment — Verified for RD25 Hydrostatic Double Drum Vibratory Roller applications, covering both listed production configurations.
- Vibration-Resistant Locking — The serrated profile resists loosening caused by the continuous drum vibration that characterizes roller operation, helping fastener assemblies stay torqued between service intervals.
- Genuine Wacker Neuson Part — Carries the full Wacker Neuson OEM designation, so the part matches the material grade and hardness spec of the component it replaces.
A serrated lockwasher is a hardened fastener component placed beneath a bolt or nut to prevent loosening under dynamic loads. The serrated teeth on its bearing surface bite into both the fastener and the mating surface, creating mechanical resistance against rotation caused by vibration or repeated stress cycles. On a vibratory roller like the RD25, where the entire machine operates under constant oscillating force, a worn or missing lockwasher can allow critical fasteners to back out gradually — leading to loose assemblies, accelerated component wear, or more significant mechanical failure if left unchecked.
