3. Rod. 4. Washered nut. 5. Jam nut. 7. Actuator.5. Install actuator (7) in governor housing opening (1).6. Move the governor control to the high idle position and hold or fasten the governor control in this position.7. Extend the actuator rod (3), by loosening the washered nut (4), to achieve a minimum dial indicator reading of 2.0 mm (.08 in.) less than the desired low power fuel setting.EXAMPLE: If the low power rack adjustment specification is 3.0 mm (.12 in.), the actuator rod (3) must be adjusted to obtain a dial indicator reading of 1.0 mm (.04 in.).8. Tighten the washered nut (4), to retract the actuator rod (3) and increase the dial indicator reading to the specified low power fuel setting.For the correct fuel setting specifications, see the Engine Information Plate or the FUEL SETTING AND RELATED INFORMATION FICHE.9. If the low power fuel setting is exceeded, repeat steps 7 and 8.10. Tighten the jam nut (5) on the actuator rod (3) and install the dust cover (6).3304 SMFS Air Only Actuator

Rack Adjustment For Engines With Sleeve Metering Fuel System (SMFS)
1. Remove the variable power actuator (1) from the rear of the governor (2).2. Use the fuel setting procedure in the service manual and adjust the high power fuel setting screw.For the correct fuel setting specifications, see the Engine Information Plate or the FUEL SETTING AND RELATED INFORMATION FICHE.3. Install the variable power actuator (1).4. Remove the back cover (6) from the actuator (1) to expose the adjustment pin (5).5. Move the governor control shaft to the high idle position.6. Turn the adjustment pin (5) clockwise to adjust the variable power control rod (8) to the fully EXTENDED position.7. To adjust the low power setting, turn the adjustment pin (5) counterclockwise to retract rod (8). Retract the rod (8) until the rack setting is decreased to the specified setting.For the correct fuel setting specifications, see the Engine Information Plate or the FUEL SETTING AND RELATED INFORMATION FICHE.8. Replace cover (6) on the variable power actuator (6).
