1994-1998 Cummins P7100 Injection Pump Drive Shaft Nut (2413318001)

The 2413318001 is the OEM-spec drive shaft retaining nut for the Bosch P7100 mechanical injection pump used on the 1994-1998 5.9L 12V Cummins. It's the nut that secures the pump gear to the drive shaft — critical hardware that should be replaced any time the P7100 pump gear is removed (rebuild, inspection, gear replacement, KDP service, or timing-cover R&R).

Pair this with the matching lock washer (CU-3920922) for a complete gear-retention rebuild. Both are one-time-use parts.
