The Wacker Neuson Locknut is a genuine OEM component designed for the DPU 100-70, DPU 100-70Le, and DPU 100-70Les reversible vibratory plate compactors. As a direct factory part, the is manufactured to the exact thread pitch and torque retention specification required for these heavy-duty diesel-powered machines. It fits all three variants in the DPU 100-70 family, making it a straightforward match when servicing any model in that series. Keep this fastener on hand to avoid interruptions during routine maintenance or drivetrain work.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact thread form and locking torque spec for the DPU 100-70 drivetrain, ensuring the nut seats and holds as intended under compaction loads.
- Drop-In Replacement — Threads directly onto the existing stud or shaft position with no reworking of mating hardware required.
- Broad DPU 100-70 Family Coverage — A single part number covers the DPU 100-70, DPU 100-70Le, and DPU 100-70Les reversible vibratory plate variants.
- Maintains Clamping Force Under Vibration — Locknut design resists self-loosening caused by the continuous vibration cycles inherent to reversible plate compactor operation.
- Critical Fastener for Drivetrain Security — A loose or failed locknut can allow shaft or pulley movement, leading to misalignment and accelerated wear on surrounding components.
A locknut is a prevailing-torque fastener engineered to resist loosening under dynamic loads and vibration — conditions that are constant during plate compactor operation. On the DPU 100-70 series, locknuts are used at key retention points in the drivetrain and exciter assembly, where maintaining a fixed clamping force is essential to keeping rotating components aligned and secure. When a locknut loses its locking ability or is overtorqued and damaged during service, it can allow connected components to shift, causing vibration imbalance, premature bearing wear, or full component separation if left unaddressed.
