I am working on a D311 power unit, it had been run without fuel filters possible till it quit. I have made missing parts and installed new filters. removed fuel pump and cleaned as best I could. Cleaned governor, fuel lines and removed injectors. Dose anyone have a croes section drawing of a9f4113 injector, and information on cleaning or rebuilding them. Thanks Steve

Throw them away and get new. Nothing you can do if flushing clean fuel through them with an injector tester and cleaning the discharge opening with a tiny drill doesn’t fix them.
I’ll

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄
