Correct location for gauge on the rack for the fuel injector (6) Fuel control rod (11) 6V-9057 Rack Synchronizing Gauge
Put 6V-9057 Rack Synchronizing Gauge Block (11) in position on one of the injectors. This gauge sits on the round part of the injector rack bar between the trim screw and the end of the rack bar. The gauge block should make complete contact with the trim screw and the surface of the rack bar. The trim screw is provided on the injectors in order to adjust the rack's zero point. This should be done AT THE FACTORY ONLY. If a unit injector has a loose trim screw, the unit injector must be replaced with a calibrated unit injector. If a trim screw has been moved, the unit injector must be replaced with a calibrated unit injector. The fuel injector cannot be synchronized if the trim screw has been moved.Note: If the correct adjustment cannot be obtained by adjusting fuel control rod (6), loosen the locknuts on rod assembly (8), and adjust the rod assembly until the correct adjustment can be obtained.
Use a screwdriver in order to pull up on each fuel control rod (4). This will ensure that the rods and the fuel injector racks are free.

Adjusting fuel control rod (typical example) (11) 6V-9057 Rack Synchronizing Gauge
While the fuel stop lever is against the synchronizing pin and the 6V-9057 Rack Synchronizing Gauge is in the position that is specified in Step 5, use a screwdriver and make an adjustment of fuel control rod (6). Slowly turn the screw on fuel control rod (6) until rack synchronizing gauge (11) fits between the fuel injector body and the shoulder at the end of the rack. Remove the screwdriver from fuel control rod (6). This will ensure that no pressure is on the linkage while the setting is checked with rack synchronizing gauge (11 ). Any pressure on the linkage by the screwdriver will not give a correct indication when the setting is checked with the rack synchronizing gauge. Move the linkage in order to ensure that the linkage is free. This will also ensure that the linkage is giving the correct setting. After you move the linkage, check the setting again.
Repeat Steps 6 and 8 for the remaining racks.
Put the 6V-3075 Dial Indicator with 5P-7263 Indicator Contact Point in 5P-4814 Collet Clamp. Install the dial indicator and the collet clamp in the threaded hole at location (Y). When the 5P-7263 Indicator Contact Point seats against fuel stop lever (10), slide the dial indicator inward or slide the dial indicator outward until the indicator reads zero. Tighten the 5P-4814 Collet Clamp enough to hold the indicator in position.
Remove synchronizing pin (2) from location (Z) .
Rotate the governor terminal shaft to the minimum fuel
