Loosen the locknuts on the governor rod assembly (2). Adjust the rod to the minimum length.
Remove the plugs at locations (Y) and (Z) from control housing (3).
Remove the synchronizing pin (1) from the storage location.
Install synchronizing pin (1) in location (Z) without the washer.

Turn the actuator terminal shaft to the "FUEL ON" position until the Surface "A" of the fuel stop lever (9) contacts the synchronizing pin (1). This is the synchronizing position or zero reference point. Hold the control linkage in this position when the injectors are adjusted. Note: You must exert a firm, steady force on the linkage while you make adjustments. The 1U-9361 Governor Torque Arm is used to apply the correct amount of force on the shaft. This shaft connects to the Woodward Governor (3161).
Remove the valve covers.

Gauge In Position On The Fuel Injector Rack
(6) Fuel control rod (right side)
(11) 6V-9057 Rack Synchronizing Gauge
Use a screwdriver in order to pull up on each fuel control rod (6). This will ensure that the rods and the fuel injector racks are free.
Put 6V-9057 Rack Synchronizing Gauge (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. Note: The trim screw is provided on the injectors in order to adjust the rack's zero point. Do not adjust the trim screw. 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.
If the correct adjustment cannot be obtained by adjusting fuel control rod (6), loosen the locknuts on rod assembly (7), and adjust the rod assembly until the correct adjustment can be obtained.

This is an Illustration of the adjustment procedure for the 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 (11) is in the position that is specified in Step 8, use a screwdriver and make an adjustment of control rod (6). Turn the screw on control rod (6) slowly. This should be done until the rack synchronizing gauge (11) just fits between the fuel injector body and the shoulder at the end of the rack. Remove the screwdriver from control rod (6). This will ensure that no pressure is on the linkage while the setting is checked with the 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 (11). Move the linkage in order to ensure that the linkage is free and move the linkage in order to ensure that the linkage is giving the correct setting. Check the setting again. Note: If the rod assembly (6) can not be adjusted, proceed to Step 12 and Step 13.
Use the rack synchronizing gauge (11) in order to adjust the remaining fuel injector racks on the right side of the engine. Recheck the fuel injector racks. Adjust the racks, if necessary. Proceed to Step 14.
Loosen the locknuts on the rod assembly (7). On the 3612 Engine, set the adjustment for the fuel control rod (6) on cylinder number 11. On the 3616 Engine, set the adjustment for the fuel control rod (6) for cylinder number 15. Set the adjustment of these rods to the midpoint of the adjustment range.
Adjust the linkage rod assembly (7) until the fuel injector rack is approximately positioned with the 6V-9057 Rack Synchronizing Gauge. The gauge must be installed on the fuel injector of the right rear cylinder (number 11 or number 15). Tighten the locknuts on each end of the linkage rod assembly (7). Repeat Step 10 and Step 11.
Put the 6V-9057 Rack Synchronizing Gauge (8) in position on the rack on one of the fuel injectors on the left side of the engine. Follow the procedure in Step 17. If the fuel injector on the left bank can not be synchronized, complete Step 15 and Step 16.
Loosen the locknuts at each end of the crossover rod (
