The Wacker Neuson is a genuine OEM Lock Washer M8 designed for a wide range of Wacker Neuson RD7 series tandem rollers and PS series submersible pumps. This is a direct OEM replacement sourced through the Wacker Neuson parts program, ensuring the correct thread engagement, hardness grade, and bite geometry for M8 fastener assemblies used throughout these product families. Compatible machines include the RD7H-ES and RD7H-S tandem rollers as well as PS2, PS3, and PS4 submersible pump models across multiple voltage and horsepower configurations. When a lock washer wears out or loses its tension, fastener assemblies can loosen under vibration — restoring this small but critical hardware keeps fastened joints secure and prevents progressive mechanical loosening across the assembly.
Key Features
- Genuine OEM Hardness and Bite Geometry — Manufactured to Wacker Neuson's specified material grade so the washer bites into the fastener and mating surface correctly, maintaining clamp load under sustained vibration.
- Drop-In M8 Fitment — Sized to the M8 thread standard used throughout RD7 roller and PS pump assemblies; seats and torques exactly as the original hardware did.
- Broad Cross-Family Compatibility — Fits RD7H-ES and RD7H-S walk-behind tandem rollers as well as the PS2, PS3, and PS4 submersible pump lines spanning 50mm, 75mm, and 100mm discharge sizes.
- Vibration Resistance Where It Counts — Compaction rollers and pump motors generate continuous vibration; a correctly specified lock washer prevents fastener back-out that can lead to loosened panels, housings, or structural connections.
- OEM Part Number Confidence — Part number 5000150763 is the authoritative Wacker Neuson reference for this washer, eliminating guesswork when cross-referencing across the RD7 and PS model ranges.
A lock washer is a hardened fastening component placed under a nut or bolt head to prevent the fastener from loosening due to vibration or dynamic loads. The washer's split or toothed profile bites into both the fastener bearing surface and the mating component, creating mechanical resistance to rotation. On equipment like vibratory tandem rollers and submersible pumps — where continuous vibration or motor torque is present — even a slightly underspec'd or worn lock washer can allow a fastener to gradually back out, leading to loose assemblies, misalignment, or component separation over time. Replacing a worn lock washer promptly with the correct OEM part restores the integrity of the fastened joint and keeps the surrounding assembly tight.
