I have a 6T 590 cummins in a case 888 excavator, it runs good but the fuel is in the oil. I changed the lift pump but the fuel is still in the oil. What should I do???? Is there a seal in the injection pump that can be changed without having the injection pump rebuilt?
Yes the shaft seal in the injection pump can be changed without rebuilding the pump, actually pretty common, not a job you want to do yourself if you don't have the knowledge though, in some cases it takes a special tool to align and compress the seal upon installation, and if you get in there and remove the pump without a clue and get it out of time you have basically shot yourself in the foot
