3. Rod. 4. Washered nut. 5. Jam nut. 6. Dust cover.4. Remove the dust cover (6) from the variable power actuator. Loosen the jam nut (5) on the rod (3). Tighten the washered nut (4) to put rod (3) in the fully retracted position.
Governor And Actuator
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
