Woodward UG-8 Governor
Adjustments
Only competent personnel should attempt to adjust fuel rack settings and the governor. The low and high idle RPM, and rack setting dimension for these engines are listed in the RACK SETTING INFORMATION.
Adjusting Low or High Idle Speed
Check the engine LOW or HIGH IDLE speed with a hand tachometer at the tachometer drive connection. The tach drive rotates at one half engine RPM.1. Set the load limit control knob (3) at 5 to prevent the engine from getting excessive fuel and from accelerating too rapidly.2. Start the engine and gradually increase the amount of fuel. When the engine has reached operating temperature, turn the load limit control slowly from 5 to 10. Use the synchronizer knob to adjust the engine speed; then, check the low or high idle stop.3. If the low or high idle stop does not permit the desired speed, adjustment is necessary. Remove the dial plate.4. Loosen the setscrew on the synchronizer indicator knob (7), drive out the tapered pin, if so fitted and remove the knob.5. Pull gear (6) out of mesh with gear (2).6. When setting the high idle speed, turn synchronizer control knob (5) clockwise until the desired high idle speed is reached. Turn counterclockwise for low idle.7. Set the high idle speed stop by turning gear (6) clockwise (counterclockwise for low idle) until the gear pin contacts idler gear (2). Mesh the gears.8. After setting the idle speed stop, turn the synchronizer control knob to change the engine speed. Return it to the desired position and recheck the idle speed. Reset if necessary.
GOVERNOR ADJUSTMENTS (Typical Example)
1-Terminal lever. 2-Idler gear. 3-Load limit control. 4-Linkage. 5-Synchronizer control knob. 6-Gear. 7-Synchronizer indicator knob. The synchronizer indicator pointer disc may be reset, if necessary. With the engine running at high idle, stop the engine by turning load limit control (3) to zero. Pry off the synchronizer indicator pointer disc and reinstall at an indication such as 12 to indicate high idle.9. Install the synchronizer indicator knob and the dial plate.Fuel Rack Setting
9S240 Rack Positioning Tool Group.
RACK POSITIONING TOOLS
1-9S227 Bracket Group. 2-8S2283 Dial Indicator. 3- 8S3675 .125 in. (3,18 mm) Contact Point.1. Remove eyebolt (4), cover (5), plug and O-ring.
EYEBOLT AND COVER
4-Eyebolt. 5-Cover.2. Install bracket (1) to fuel pump housing.
BRACKET INSTALLED
1-Bracket.3. With the governor in shut-off position, place spacer (6) of the bracket group between the shoulder on the rod in bracket (1) and the bracket. Apply pressure toward the fuel pump housing to hold the spacer snug.
DIAL INDICATOR INSTALLED
1-Bracket. 2-Dial indicator. 6-Spacer.4. Install and zero indicator (2), then tighten the bracket screw and remove spacer (6).
COVER FOR RACK ADJUSTING SCREW
7-Lock wire. 8-Cover.5. Set the governor load limit control knob on 10. Using the lever on the governor terminal shaft, move the fuel rack from the FUEL OFF position toward the FUEL ON position until contact is made with adjusting stop screw and read the rack setting gauge. Compare the rack travel value with that listed in the RACK SETTING INFORMATION.
Do not force the engine linkage toward increased fuel without first turning the load limit knob to 10.
6. If the full rack travel is not the value listed in the RACK SETTING INFORMATION, cut lock wire (7), remove cover (8), loosen the adjusting screw locknut and disengage the lock so the adjusting screw can be turned freely.7. Turn the adjusting screw counterclockwise to increase the fuel rack travel or clockwise to decrease the rack travel. When the fuel rack is correctly adjusted, lower the lock into the nearest notch, tighten the locknut and install cover.8. Install lock wire and seal.Compensating Adjustment
Although the governor may appear to be operating satisfactorily at no load, high overspeeds and underspeeds after load changes and slow return to normal speed are the results of incorrect compensation adjustments.Make compensating adjustments after the temperature of the engine and the oil in the governor have reached normal operating values and with the engine running at no load conditions.1. Loosen nut (1) and set compensation adjusting pointer (2) at MAX.2. Remove plug (3) and, use a screwdriver to open the compensating needle valve three or more turns.3. Allow the engine to surge for about 1-1/2minutes to bleed trapped air from the governor oil passages, then turn compensating needle valve until surging stops. The needle valve must be approximately 1/8 turn open.
COMPENSATING ADJUSTMENT
1-Nut. 2-Compensating adjusting pointer. 3-Plug.4. Lower the pointer to two points above MIN.5. Move the governor terminal shaft manually to increase engine RPM, then let go and let the governor stabilize. If it takes too long to stabilize, move the pointer toward MAX two more points. Continue until the governor stabilizes, without too much over and under speed.Governor Linkage Adjustment
