In general, a jam nut is a locking nut, typically thinner than a standard nut, that is tightened against another nut or against a mating surface to resist loosening under vibration. Its exact dimensions, material and any thread specification are not stated in the catalog record and should be checked against the catalog or the equipment before use.
Part number 0219791 is the number to reference when ordering this jam nut. The catalog associates it with a 3406B drive group-pump listing with recorded serial and configuration conditions, so confirm those conditions match your machine before ordering.
