4C-8753 Extended Collet     1    
6V-3075 Dial Indicator     1    
5P-7263 Indicator Contact Point     1    
8T-2684 Rack Synchronization Gauge     1    Refer to Special Instruction, SEHS9278 for the instructions on the use of the 4C-8753 Extended Collet .Fuel setting is the adjustment of the fuel setting screw to a specified position. The fuel setting screw limits the power output of the engine by setting the maximum travel of all the fuel injector racks.

Refer to Testing And Adjusting, "Fuel Injector Synchronization". After the injectors are synchronized correctly, leave the synchronization pin in place for the procedure that follows.
Put 6V-3075 Dial Indicator (2) with 5P-7263 Indicator Contact Point Contact Point (4) in 4C-8753 Extended Collet (3). Remove the plug from the right side of fuel setting cover (8) .

Checking fuel setting (typical example) (2) 6V-3075 Dial Indicator (5) Synchronization pin (8) Fuel setting cover
Unscrew synchronization pin (5) by 25 mm (1 inch) or remove synchronization pin (5). Slowly move the governor or the actuator terminal shaft toward the fuel ON position until the flat face of the fuel stop lever is against the end of the fuel setting screw. The dial indicator reading will be the present fuel setting when the linkage is held in this position.Note: Refer to the TMI (Technical Marketing Information) for the correct fuel setting.
If the fuel setting is correct, remove the dial indicator and the synchronization pin. Install the two plugs, and install the synchronization pin back into cover (8) .
If the fuel setting needs adjustment, see "Fuel Setting Adjustment".
A mechanic with governor and fuel setting training is the ONLY one to make adjustments to the engine fuel setting.
Fuel Setting Adjustment
Cut the seal wire and remove fuel setting cover (8) and the gasket. Loosen locknut (7). Hold the fuel stop lever against the end of the fuel setting screw. Turn the fuel setting screw clockwise or counterclockwise until the correct reading is on the dial indicator.
