Wacker Neuson 5000216640 Locknut

The Wacker Neuson Locknut is a genuine OEM component designed for the DPU and BPU series reversible vibratory plate compactors, spanning the DPU80L, DPU90L, DPU110L, DPU130Le, DPU5247H, DPU5260H, DPU5275H, DPU6260H, DPU6275H, BPU5260Ah, and BPU6275Ah families. As a genuine Wacker Neuson part, the is manufactured to the same tolerances and material specifications as the original hardware installed at the factory. This Locknut covers an exceptionally wide range of DPU and BPU configurations — including standard, reversible, and combination-plate variants across diesel and electric drive models — making it a high-confidence choice when sourcing fastener hardware for these machines. Verify your machine's model number before ordering to confirm fitment within this broad compactor lineup.

Key Features

• Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's specified thread class and torque rating for this fastener position, ensuring the locking mechanism holds under continuous compaction vibration.
• Direct Drop-In Hardware — Matches the original thread pitch, diameter, and locking profile, so it installs in the same position with the same tooling used on the original assembly.
• Broad DPU and BPU Compactor Coverage — Fits a wide range of reversible vibratory plate compactors including DPU80L, DPU90L, DPU110L, DPU130Le, DPU52xx, DPU62xx, DPU5275, DPU6275, BPU5260Ah, and BPU6275Ah series machines.
• Vibration-Resistant Locking — The self-locking design resists loosening caused by the high-frequency vibration inherent to plate compactor operation, maintaining clamp force across extended service intervals.
• Verified Genuine Part — Sourced directly through the Wacker Neuson OEM supply chain, carrying the correct part number 5000216640 for accurate cross-referencing against your machine's parts manual.

A locknut is a fastener engineered to resist self-loosening under dynamic load and vibration. Unlike a standard nut, its locking feature — whether a nylon insert, distorted thread profile, or prevailing-torque design — maintains clamping force even when the assembly is subjected to the constant oscillation that plate compactors generate during operation. On reversible vibratory plate compactors like the DPU and BPU series, fastener security is critical: a locknut that has backed off or lost its locking effectiveness can allow mating components to shift, creating excessive play, accelerated wear on adjacent parts, or structural instability within the machine. Replacing a worn or compromised locknut promptly restores the intended joint integrity and prevents secondary damage to surrounding hardware.
