The Wacker Neuson is a genuine OEM Lock Nut designed for a range of Wacker Neuson vibratory plate compactors, centrifugal trash pumps, and single-drum vibratory rollers — including the WP1550V, WP1550VW, VPG165V, PT2V, PT3V, and RS800V. Sourced directly from Wacker Neuson, this Lock Nut is an exact match to the original hardware installed at the factory. Correct thread engagement and torque retention are critical across all of these machine families, and the delivers both. Keep a spare on hand — fastener wear or loss is one of the most common causes of unplanned service interruptions across mixed equipment fleets.
Key Features
- Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's original thread profile and hardness spec, ensuring consistent clamp load and resistance to backing off under vibration.
- Drop-In Hardware Replacement — Matches the original fastener dimensions exactly, threading directly into the existing mating hardware without chasing or rework.
- Broad Fleet Coverage — A single part number covers WP1550V and WP1550VW vibratory plate compactors, VPG165V vibratory plate, PT2V and PT3V centrifugal trash pumps, and the RS800V single-drum vibratory roller.
- Vibration-Resistant Locking Design — The lock nut's locking feature is engineered to hold position under the continuous vibration loads these machines generate, preventing fastener loosening during operation.
- Verified OEM Part Number — Ordering by Wacker Neuson part number 5000086854 confirms you receive the correct specification nut — eliminating guesswork when sourcing hardware across a mixed equipment lineup.
A lock nut is a fastener designed to resist loosening when subjected to vibration or torque — a critical requirement on compaction equipment, pumps, and rollers that generate continuous dynamic loads during operation. Unlike a standard hex nut, a lock nut incorporates a locking mechanism (such as a nylon insert, prevailing-torque profile, or distorted thread) that maintains clamping force even as the machine vibrates. When a lock nut fails, strips, or goes missing, the joint it was securing can work loose, leading to misalignment, accelerated wear on surrounding components, or mechanical failure of the assembly it holds together. Replacing a worn or missing lock nut promptly with the correct OEM specification part is one of the simplest ways to protect the integrity of a larger, more expensive assembly.
