Fuel Setting on the 3116 is checked by reading the maximum fuel rack travel.
The Cat tool kit provides a long pin on a handle that inserts through the Governor link pin which has a drilled hole through the center.
Then a fork shaped tool is wedged between the head and the pin to eliminate any Governor movement.
The digital dial indicator arm is placed on the end of the injector rack pin on #1 injector.
The injector is manually put into no fuel position, the dial indicator is set to zero then rack is released. This measures the maximum fuel rack movement.
The Maximum fuel setting specification is on the top of the valve cover.
