The Wacker Neuson Jam Nut 14mm is a genuine OEM fastener designed for the DS70 and DS720 diesel vibratory rammer series. As a direct Wacker Neuson OEM component, part is manufactured to the exact thread pitch, hardness, and dimensional tolerances required for proper installation and secure retention. This nut is confirmed to fit multiple DS70 and DS720 configurations, including 11-inch and 13-inch shoe variants across both EPA-compliant and standard models. Keeping the correct fastener in place is critical to maintaining the structural integrity of the rammer's working components, so having the right part on hand matters.
Key Features
- OEM Thread and Hardness Specification — Manufactured to the exact 14mm thread specification required for secure locking in DS-series rammer assemblies, preventing loosening under sustained vibration loads.
- Drop-In Installation — Matches the original fastener profile for direct installation with no reworking of threads or mating hardware.
- Broad DS70 and DS720 Fitment — Compatible across DS70 and DS720 diesel vibratory rammer variants, including 280mm/11-inch and 330mm/13-inch shoe configurations and EPA-rated models.
- Vibration-Resistant Locking Design — Jam nuts are specifically engineered to resist loosening under high-cycle vibration — the exact operating condition of a diesel rammer — protecting downstream components from fastener failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, ensuring the part number 5000155337 matches your machine's original build specification without substitution.
A jam nut is a thin, secondary nut threaded onto a bolt or stud and tightened against a primary nut or surface to lock both in place and prevent unintentional loosening. In a diesel vibratory rammer like the DS70 or DS720, components are subjected to continuous, high-frequency impact forces that can work standard fasteners loose over time. The jam nut counteracts this by creating a clamping force between itself and the adjoining hardware, maintaining tension throughout operation. When a jam nut wears, strips, or goes missing, the primary fastener it secures can back off, leading to component misalignment, accelerated wear, or mechanical failure in the rammer's working assembly.
