Governor woes

Ok, long time lurker via Google. I have what I believe is a 46 9n. I'm in the process of changing the governor and the tractor now only has two speeds. Idle and overspeed
overspeed is achieved with one click of the throttle plate . I'm now aware I need to adjust the new governors internal play if you will via shims and the arms need adjusted with a ford governor jig. My question is where does one find this jig? My linkage is not threaded so it cant be adjusted that way. My only options are to bend the linkage or the governor arms, hence why I'm looking for the jig. Also, if i have this right, the shims on the shaft inside the governor are why I'm having engine speed control problems. Is this correct?

PROBLEM SOLVED!!!!!!!!

Firstly, thank you to everyone with their responses and posts. the information you guys put forth was vital in solvng the problem. Thank you so much everyone!

The fix:

First, the shaft shims were not right. it wasnt .220-.230. I added a washer to make it up and get in back in spec.

Second issue:

The fork that rides on the arm shaft....really precise name i made there...WAS UPSIDE DOWN. It was put together improperly from wherever it came from. It fits together that way so I can see how it happened. I actually didnt notice it until I started looking at the old one to see if i could scalp the linkage arms from it. Once I realized that, I switched it and it works perfectly.

Third issue:

The linkage arms were nowhere near in line with my existing carb and throttle linkage. The fix for this would have been to bend my linkage but I would have had to bend my carb linkage into a sharp V and the the throttle linkage wouldnt clear the exhaust manifold. There is a jig you all are aware of that allows you to hammer the arms into the proper alignment. I dont have one nor could I find anyone that has one so....I beat the ever loving snot out of it on an anvil. After much cussing and fitting, I got the arms in the proper postion so I did not have to bend my linkage at all.

Im hoping to do some brush hogging tomorrow if the weather permits. I did have to do some carb adjustments as it was adjusted to compensate for the failing governor. Im sure Ill have to do some more fine tuning to get it going perfectly but by god IT WORKS!

Thanks again everyone. To all who opt for an amazon governor, they do work. just take them apart and assume they are put together improperly. check the shimmable gap and be ready to either swap your old arms into the new unit or get you bfh out.

Suggest look for a reason the fork isn't pulling back the aprox 1/8 inch at idle, like it should. It may have slack up to the fork base, or it may be all the way back hitting the housing. Either one would give the high revs.

Check that the fork isn't pinned on backwards.

I put one on backwards, and it fits on, and puts the arms more twards the carb, than when on correctly. 1/8" punch will drive the tapered pin out, after unscrewing the oil line fitting.

So, are we making the assumption that the aftermarket, nonfunctional governors just need adjustment?

Hi JMOR,I suspect the jig numbers are correct, but measured from the edge of the connector ball, not the middle. Would have been consistant for the book to have given values to the edge. 😃

The 2.450 on the jig with a .020 gasket = 2.47,,, which is the long demension.
My 2.56 isnt too far from spec, and it works, no overspeeding.

Quoting Removed, click Modern View to seeyour 2 9/16 is closer to dimension quoted in manual than number drawn in on picture & I cannot explain that, as those were said to be actual measurements by the owner of that fixture????

I haven't had the pleasure of working on an aftermarket gov, and do not have the tool/ jig.
My great running 8n, with engine off, full throttle, measures 2 9/16 in from the flat spot in the pic, to the small arm.( trying to simulate the jig measurement, with gasket)
If the aftermarket govs small arm is too long in this dimension, seems it would give high rpm. I grinded an old welding rod to fit, then measured the rod.
Not as precise as the jig, but may be helpful.

Quoting Removed, click Modern View to seeThat fixture is a bit over-blown, as all it does is give you flat surfaces to make arm measurements on and to lay arm on to hit with hammer to bend arm into position measured.

Hcooke you're right. The answer is always the same. You shouldn't have bought the aftermarket one. There weren't any remans on Ebay at my time of purchase. The ones I've seen in the past were up to $500. No way in h#ll I'm paying that for something rebuilt that is still a gamble. I'm hoping someone who knows something will chime in eventually.

New 8/9/2N governors have a bad reputation. Go to ebay or some other source and buy a OEM governor and rebuild it.

Same problem / different day.

Nobody ever seems to have the answer to the aftermarket governor problem.

I hope you figure it out and let the rest of us know.
