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?
 
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.
 
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.

hat 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.

This is perfect! Exactly what I was
hoping to see. I will do.some tinkering
this weekend to see if I can get close
 
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.

our 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????
 
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.
 
(quoted from post at 23:16:03 06/19/20) So, are we making the assumption that the aftermarket, nonfunctional governors just need adjustment?
'm not. But maybe I will learn something?
 
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.

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.
 
Way to go Putt_Putt !!!!

Thats great news you got to beat the
snot out of your gov, and he/ she
finally came around!

Hope it works properly in your test.
Post pics if you can.
