Help adjusting droop on John Deere 4045

[Bergz22]

Electronic governors are not necessarily electronic engines either. On a Stanadyne pump like that they just replace the top cover with one that contains a governor actuator, which is just a device that manipulates the shutdown linkage directly. Then you set the mechanical governor higher, up and out of the way so to speak, and the electronic governor pulls it back down to 1800 on the button. Electronic is nice but mechanical is nice in its own way.

You are right. I meant full electronic engines. But they come with their own problems. This one does have a 12v solenoid on the injection pump. It has one switch. Flip up, it cranks and then runs by itself with a Murphy shutdown system.

All ya gotta do is follow my instructions on pg 1..
“I” wouldn’t touch that adjustment screw on the lever.. not until u removed the top cover n got the coils started correctly.!!!

I will follow your instructions. They were not that clear.

Ok. Here’s what I see when I open the cover. I didn’t see the internal screw unless I’m missing it.

Back out the droop knob until u have 7 coils of spring on the end of the knob

Would the knob be the black piece in the middle of the spring?

 

[thepumpguysc]

Yes

 

[Bergz22]

Yes

Counting 7 coils on the end of the knob, the droop screw is out as far as it will go if I have it correct.

Or like this?

The 1st pic is correct...
But now.. u have to take the small “hat” and screw it till it JUST TOUCHES THE SPRING..
All his is usually done w/o the throttle shaft in the way..
Just move the throttle to the low idle position inorder to get to the hat that the throttle lever is pushing on..
The bottom pic is probably where you’ll end up at..tho.

Which picture is the correct one? The one posted at 3:00 or 3:02?

 

[thepumpguysc]
