Ford 800 governor malfunction

Ravgardner · Jun 20, 2022

Friend just got a Ford 800. The throttle does not respond like it should. Not a positive speed up or idle. Never experienced this with a tractor before. So Im thinking it might be a problem with the governor. Anyone have so ideas to give?

Could be as simple as a linkage problem. Make sure all the linkage moves as it should when not running. Then with it running and throttle set at idle grab the gov. to carb rod and try to open up the throttle with it and see if the gov. tries to fight you

Assume this is a gas engine...

To check the governor, begin with the engine off.

Dash lever set to idle, the carb should be fully closed against the idle stop.

Dash lever set for fast, the throttle should be in the wide open position.

Inspect the linkage and throttle shaft. There should not be excess wear in any of the pivot points, nothing touching the linkage, binding, rubbing, etc.

Start the engine, again the throttle should be held against the idle stop when the dash lever is at idle, not the governor holding it at idle. If the governor is holding it at idle it will be prone to surge and not idle consistently.

Bring the RPM up to full governed speed. Manually push the throttle closed at the carb. When the engine idles down, release the throttle. It should instantly spring wide open and modulate down to the governed speed.

If it is surging, try richening the mixture.

Keep in mind, the governor's sole purpose is to maintain the selected engine speed. It can only work as well as the engine allows. If the engine does not respond to throttle position, the governor doesn't care, it just positions the throttle.

would you be able to post a picture of the linkage... I've owned mine for years and it's never worked properly. The springs are bent up and cobbled to where it really doesnt govern... I have to work the throttle up over small hills etc to maintain rpms

There is compensating spring you can get new. Also, get your 600-800 Owner's Manual and I&T F0-20 Manual. May need to get into the PROOFMETER section as well.

It is most likely the linkage There is a step by step procedure in the owners manual for setting it.

Thanks. I think with new springs I should be able to set it. Thanks foe the reply
