Why Choose Broken Tractor:

  • ✅ Kit number and pump number both listed — Cat sells this as kit 397-5683 with pump 380-2002 inside — search either and you land here.
  • ✅ Engine-matched, not model-matched — We name the 3054C pump so E-series owners do not order the C4.4 part.
  • ✅ ready to ship from our U.S. warehouses — Louisiana and Ohio.
