Wacker Neuson 5100017158 Locknut

The Wacker Neuson 5100017158 is a genuine OEM Locknut designed for DPU80, DPU90, and DPU110 series reversible vibratory plate compactors and BS62 and BS68 series gasoline vibratory rammers. As a factory-sourced component, part 5100017158 meets the exact material and dimensional specifications set by Wacker Neuson for these machines. Fitment spans a wide range of DPU80, DPU90, and DPU110 variants — including Lec, Lem, Lekc, and reverse-drum configurations — as well as multiple BS62 and BS68 rammer models. Verifying your machine model against the compatibility list before ordering ensures a correct, hassle-free installation.

Key Features

• Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's exact torque and thread-engagement specifications, ensuring the locknut holds secure under the high-vibration operating conditions of compactors and rammers.
• Direct Drop-In Replacement — Matches the original fastener profile and thread pitch, seating correctly in the same position as the factory-installed unit without modification.
• Broad DPU Series Coverage — Fits DPU80, DPU90, and DPU110 reversible vibratory plate compactors across Lec, Lem, Lekc, and reverse-drum (r) variants, including US-market and KMAT configurations.
• BS Rammer Compatibility — Also fits BS62 and BS68 gasoline vibratory rammers, including standard, lb, and Sunbelt rental-fleet variants, making this a versatile fastener across your equipment lineup.
• Vibration-Resistant Locking Design — A properly functioning locknut prevents critical fastened joints from backing off during operation; a missing or worn locknut risks loosening of key assemblies, leading to component damage or unsafe machine behavior.

A locknut is a fastener engineered to resist loosening under sustained vibration — a critical requirement in compaction equipment and rammers, where mechanical vibration is continuous during operation. Unlike a standard nut, a locknut incorporates a locking feature (such as a nylon insert, distorted thread, or prevailing-torque design) that maintains clamping force even as the machine vibrates. When a locknut fails, backs off, or is incorrectly replaced with a standard nut, the joint it secures can loosen progressively, potentially allowing components to shift, wear unevenly, or detach entirely during use.
