Bosch VE Injection Pump Gasket Kit Dodge Cummins DGK121

The 20mm drive shaft is standard on the Bosch VE pumps used in Dodge Cummins 5.9L 12-valve engines (1989–1998) and many Case tractor and industrial applications. If you're rebuilding the pump off a Cummins 5.9L 12V, DGK121 is the correct kit. If you're unsure, measure the diameter of the pump drive shaft or call (818) 261-3896 with your vehicle and pump details.

This is a complete reseal gasket kit — it covers all O-rings, gaskets, and drive shaft seals needed to stop leaks and reseal the pump housing. It does not include internal mechanical components like delivery valves, advance pistons, or governor springs. For a complete mechanical overhaul you'd need additional internal parts; for stopping leaks and resealing the pump externally, DGK121 is all you need.

Yes. The Bosch VE rotary injection pump was used across many diesel applications beyond the Cummins — including Case tractors and other agricultural/industrial equipment. As long as your pump is a Bosch VE design with a 20mm drive shaft, this gasket kit is correct regardless of what vehicle or machine it's installed in.
