ON-ENGINE SPEED DROOP GOVERNOR ADJUSTMENT
Start engine and apply approximately 50 percent load until engine reaches normal operating temperature.
If engine surges during warm-up period, turn speed droop adjusting cap clockwise until surging stops.
When engine has reached operating temperature, position throttle to get full load speed and apply 100 percent load.
Adjust throttle if necessary to obtain satisfactory 100 percent load performance.
Remove load and check for no-load speed. If incorrect, adjust speed droop adjusting cap in small increments (turn
clockwise for increased droop or counterclockwise for less droop). If surging exists when load is removed, turn speed
droop adjusting cap clockwise to eliminate.
When speed droop adjustments are made, throttle position adjustments (WP 0046 00) will also be necessary.
Recheck 100 percent load and no-load performance and readjust as necessary.
