Rapidly change the position of the output shaft 5 to 15 degrees. The 

controlling rpm should change several rpm, then return slowly towards the 

original controlling rpm at 20 degrees output shaft position. 

5. Turn the needle valve counter-clockwise one turn. The speed should return 

to the original controlling rpm ±3 within 10 seconds. 

6. Adjust the governor to control at 400 rpm, 20 degrees output shaft position. 

 (a) The minimum torque required to force the governor output shaft to 

minimum fuel is 11 lb-ft or 132 lb-in (14.9 Nžm). 

 (b) The minimum torque required to force the governor output shaft to 

maximum fuel is 10 lb-ft or 120 lb-in (13.6 Nžm). 

7. For an output shaft rotation from 2 degrees to 38 degrees, the change in 

rpm must not exceed 3 rpm. Reset the droop slider if a larger speed change 

occurs. 

8. Remove nameplate. Set the high speed stop to the specifications for your 

governor. Place stop lever on serration that allows equal length of stop 

screws. Lock lever in place. 

9. Set the low speed stop to the specifications for your governor. Adjust the 

speed setting indicator (if so equipped) to read “zero” and lock it in place. 

Set the servo stop at 40 degrees and tighten the jam nut. Install nameplate. 

10. Stop governor drive shaft rotation. Depress the shutdown strap several 

times to bleed all governor pressure. Replace test cover with governor 

cover. 

11. Remove the shutdown cover. Adjust the nut on the shutdown strap so the 

governor just begins to shutdown when top of the nut is even with the top 

surface of the cover, then turn the nut one turn clockwise. Replace the 

shutdown cover. 

12. Turn the compensating needle valve clockwise to stop, and then 

counterclockwise 1/2 turn. 

13. The governor must not have any external leaks.
