Actuator Installation - Woodward EG-3P Installation Manual

Installing EG-3P on Detroit Diesel I-71 Engine
See Figures 1 and 2 to install the EG-3P actuator on the engine.
1. Remove the SG governor from the engine.
2, Install hold down studs (10) in the actuator pad.
3. Install drain adapter gasket (13) and the EG-3P actuator on the hold down
studs.
4. Install boot adapter assembly (9), boot (8), jam nut (6), and rod end (5) on
new fuel rod (7).
5. Attach fuel rod (7) to the engine fuel rack. Use cotter pin (14).
6. Install the actuator on the engine. The linkage must move freely.
7. Attach the terminal lever to the actuator, and adjust travel.
WARNING—MINIMUM/MAXIMUM FUEL POSITIONS
Be sure to allow sufficient undertravel at the min-fuel position so the
governor can create a shutdown, and also 3 to 4 degrees overtravel between
full load and maximum fuel to ensure better transient performance.
Adjustment of the fuel linkage must provide for control of fuel from
SHUTDOWN to FULL FUEL within the limits of the 42 degrees of governor
output shaft travel. It must also provide for approximately 28 degrees output
shaft travel between NO LOAD and FULL LOAD. Adjust the linkage so the
maximum stop of the actuator will prevent the fuel rack from traveling
beyond the full fuel position. The fuel injectors must move freely.
8. Install the oil line from the oil reservoir to either of two 1/8" pipe tapped inlet
holes of the actuator. A minimum of 5 psi (34 kPa) oil supply pressure is
recommended. The supply should be filtered engine oil.
9. Include overspeed shutdown equipment separate from the speed control
governor.
