The Wacker Neuson Locknut is a genuine OEM component designed for the DPU 100-70 and DPU 100-70Le series reversible vibratory plate compactors. As a factory-sourced part, the matches the original specification exactly, ensuring correct installation and secure fastening without the guesswork of adapting a non-specified alternative. This locknut is confirmed to fit the DPU 100-70, DPU 100-70Le, and DPU 100-70Les models, making it a straightforward service replacement for technicians working on these heavy-duty diesel reversible plates.
Key Features
- Genuine OEM Thread Specification — manufactured to the exact thread pitch and hardness grade of the original, so it seats and torques correctly without stripping or backing off under vibration.
- Vibration-Resistant Locking Design — the locking feature is engineered to hold its position under the continuous high-frequency vibration environment produced by DPU-series reversible plates, maintaining clamping force over extended service.
- Direct Swap for DPU 100-70 Series — confirmed fitment across the DPU 100-70, DPU 100-70Le, and DPU 100-70Les, so you can order with confidence against your machine's model number.
- Correct Torque Retention — a worn or missing locknut on a high-vibration machine like the DPU 100-70 can allow critical fastened assemblies to loosen in service; this OEM replacement restores the intended clamp load and keeps fastened joints secure.
- Factory Part Number 5000208903 — sourced directly through the Wacker Neuson parts network, so you receive the identical component supplied at original equipment build.
A locknut is a specialized fastener designed to resist self-loosening under dynamic loads — particularly the intense cyclical vibration generated by reversible vibratory plate compactors like the DPU 100-70 series. Unlike a standard nut, a locknut incorporates a locking mechanism (such as a prevailing-torque collar or nylon insert) that maintains clamping force even as the machine vibrates through continuous compaction cycles. When a locknut wears out, deforms, or is lost during service, the joint it secures can gradually loosen, leading to misalignment, accelerated wear on surrounding components, or mechanical failure during operation. Replacing it promptly with the correct OEM-specified part keeps the assembly tight and the machine performing as intended.
