The Wacker Neuson Jam Nut is a genuine OEM component designed for the G70, G100, and G120 series mobile generators. As a direct OEM replacement sourced through authorized channels, this part meets the exact specifications of the original hardware. It fits a wide range of G100 and G120 configurations including cold weather, Tier 4i, Hertz, and Transport Canada variants, as well as the G70 mobile generator. Confirm your model and machine number before ordering to ensure correct application.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to the exact thread pitch, dimensional tolerance, and material grade of the original Wacker Neuson jam nut — no guesswork on fitment.
- Broad G-Series Generator Coverage: — Fits G70, G100, and G120 series mobile generators across standard, cold weather, Hertz, Tier 4i, and Transport Canada configurations.
- Direct Drop-In Replacement: — Threaded to match the original fastener position; installs using standard hand tools with no reworking of the mounting point.
- Locking Integrity Restored: — A properly torqued jam nut holds critical assemblies in position under vibration and load; a worn or missing jam nut allows unwanted movement that can lead to component misalignment or loosening over time.
- Verified Part Number: — Part number 5200000319 is the active Wacker Neuson OEM reference, replacing earlier part numbers across multiple G100 and G120 build variants.
A jam nut is a thin secondary nut threaded onto the same fastener as a primary nut or adjustment screw, then tightened against it to lock both in position. On Wacker Neuson G-series generators, jam nuts are used to secure adjustable components — such as linkages, threaded rods, or bracket hardware — preventing them from backing off under the vibration generated during operation. When a jam nut is missing, damaged, or has lost its clamping force, the primary fastener can work loose over time, potentially causing misalignment, abnormal wear, or loss of adjustment on the affected assembly. Replacing a compromised jam nut promptly keeps the generator's mechanical connections tight and correctly set.
