Well, my 990 Case is 40 years old and the tank leaked and after epoxying the bottom water was entering the defective fuel sender unit so I sealed it with epoxy also. Had the injector pump rebuilt and a new lift pump will be installed once I fabricate a new push rod out of drill rod as the old one was concave on the cam side and the fuel pump lever had made a groove in that side, I can only imagine what the camshaft looks like. I think the push rod is 36MM long??? I'm making an injector adjusting device using an old but good bottle jack, just need a few more pieces so I can adjust the injectors to 1750 PSI if that is correct??? I had to rewire the whole system except now the key will not energize the starter solenoid. Maybe I need another switch as water could have gotten inside the old one and you know the story. I'll have to wait till the tractor is running to determine if the radiator will need some work as the cores look like they have calcium buildup from what I can see from the raditor cap opening. Can anyone help me with the length of the push rod and the set pressure of the injectors?
