Setting rack(4) Setting governor (setting maximum speed )(a) While applying the full load to the engine, hold the speed control lever in the specified maximum speed position.(b) Adjust the governor setting bolt (maximum speed setting bolt) to the specified speed position, and set it there.
Setting governor(5) Setting torque spring (optional specification)Set the speed control lever at the maximum speed, and apply the load to the engine. Turn the torque spring adjusting screw until the engine delivers the specified output at the specified speed. Fix the screw with the locknut, and install a cap to the lock nut.
Setting torque spring(6) Measuring speed variationMeasurement of speed variation at removal of load.(a) Operate the speed control to set the engine at the rated output and speed.(b) From this condition, instantaneously remove the load to put the engine into the no-load condition. Operate the engine with the speed control lever fixed.(c) The engine speed temporarily jumps up then lowers and stabilizes. Record the momentary maximum speed, stabilized speed, and time from the removal of the load to the stabilization of the speed.Measurement of speed variation at application of load.From the no-load condition, instantaneously apply the specified load to the engine. Record the momentary maximum speed, stabilized speed, and time from the application of the load to the stabilization of the speed.Calculation of speed variationCalculate the speed variation from the measured results. When the speed variation falls outside specified limits, adjust the governor notches.
Measuring speed variation(7) Adjusting speed variation (adjusting governor notches)(a) Adjust the speed variation by turning the adjusting screw of the swivel lever.(b) Remove the plug at the top of the governor, and set the speed control lever to the low idle speed position. The swivel lever turns up to reveal the head of the adjusting screw. Turn the adjusting screw with a flat-head screwdriver.(c) The speed variation decreases as the adjusting screw is tightened and increases as the adjusting screw is loosened. One notch equals a quarter turn of the adjusting screw and changes the engine speed by three to five revolutions.(d) Turning the adjusting screw changes the governor spring tension and hence the maximum speed. Readjust the governor setting bolt.(e) The maximum speed increases as the adjusting screw is tightened and decreases as the adjusting screw is loosened.
The adjusting screw can be loosened by 20 notches (or five turns) from the position where it is fully tightened. It is dangerous if the adjusting screw is loosened more.
Adjusting speed variation(8) SealingSeal each setting bolt.Break-in Operation
When the engine is overhauled, it should be mounted on a dynamometer and operated for break-in and inspection.Starting Up
(1) Before starting the engine, check the levels of coolant, engine oil and fuel, and bleed the fuel and cooling system.(2) With the fuel supply cut off, operate the starter and crank the engine for about 15 seconds to circulate engine oil.(3) Move the speed control lever slightly in the direction for increased fuel (do not move it to "full injection" position), and then turn the starter switch
