MF 35 govenor how to test - doesn't seem to work - details?

tysmobiletractor · Oct 17, 2019

Massey Ferguson TO 35 gas. Owner has complained govenor quit working. Throttle tends to run off higher on its own occasionally.

I've done numerous likage adjustments, following the book and tweaked the set screw in the timing cover back and forth 1/2 turn at a time.
Haven't got the govenor to kick in at any time.
Lock the brakes, in high range 3rd low idle, slowly let out clutch.

So

At what point do I need to replace govenor with new internal components?

I don't like to throw parts at something hoping it will help.

But I think that's about where its at.

Is there anything else I should look at first? Or just rebuild govenor and be done with it..?...

Thanks

Sounds like a common problem with these.
If anyone has experience with this please let me know.
Thanks

I've struggled to get mine set right. It works OK, but it's not as good as it should be. I recently found the instructions at the link below.

I'd post the file but I can't figure out how to do it.

tysmobiletractor · Oct 17, 2019

ok thanks
I think I have done all that already
But I'll double check

What tends to happen is the sheet metal cage that holds the metal balls in breaks (around the area indicated by the red lines in the picture). Those pieces along with the metal balls fall into the oil pan. You maybe able to fish out all the parts through the oil drain plug in the old pan, but the front axle support has to come off so you can remove the crank pulley, and the front cover on the engine to replace it.

Before taking it apart drain the engine oil, and see if those parts are laying in the bottom of the oil pan. You should be able to fish them out with a magnet.

tysmobiletractor · Oct 18, 2019

Thanks much
That makes perfect sense.

tysmobiletractor · Oct 18, 2019

I ll check into the oil and repost my findings.

tysmobiletractor · Dec 3, 2019

Decided to order the governor kit and get replace it.
Tore it down and found the original one in better condition than I thought. All the ball bearings stayed together as I removed them.
Replaced everything with the new parts.
Back together, and same symptoms as at the start.

I've tried numerous linkage adjustments.

I have yet to get the governor linkage to kick in and move enough to show me that it even works.

Currently, the high rpm is wild, and wants to rev way above pto range. It was doing something similar originally.

It runs great at low rpm and idle.

Any similar experience? Let me know your thoughts on best procedure. This is a great little tractor. Just needs some tweaking of some sort.
Thanks

So, the umbrella in the govenor kit has a square metal tab that sticks out, kit I purchased from external link, and in the video from external link showing this installation, you are told the tab needs to be at 8:00
Sounds simple enough.
However the instructions that come with the kit from Steiner say the arrow on this umbrella needs to be in the UP position to the engine. 1st off, there is no arrow on the umbrella. So, do they mean the tab is to be in the up position? I would guess so from the picture. But that is far from 8:00!

I installed mine at 8:00, mostly because it was very specific. Of course, mine is not working. Just adds to the confusion.

Is it up?
Or 8:00?

Looking at the cover, and the position is makes contact in the cover, looks like UP if I had to guess.

I may need to take mine back off a 2nd time. That's why I want to know.

tysmobiletractor · Dec 3, 2019

The govenor kit I ordered from external link had instructions saying the umbrella had an arrow on it that needs to be in UP position or top of motor. Except there is not arrow on the umbrella. Do they mean the small tab that sticks out?...
I think so, but adding to the controversy, a Steiner video on the installation says the tab has to be at 8:00. Thats far from UP!
So, I called Steiner, a tech said the tab should be installed so it contacts the stop inside the cover. To me, that looks like about 12:00.

So, if I installed mine at 8:00, which I did, what are the consequences?

Mine is not working. I may likely take it off again and reposition it. Just trying to understand what is really going on before I do any more.

tysmobiletractor · Dec 4, 2019

Is this working?

tysmobiletractor · Dec 4, 2019

Very irritating. I wrote 3 responses with additional info. and none of them ever showed up!

tysmobiletractor · Dec 4, 2019

The govenor kit from external link that I purchased and installed said the umbrella installed needs to have the arrow in the UP position or top of motor. But there is no arrow on this umbrella. It looks from the picture this may be the metal tab that sticks out?...
The Steiner video on the instalation says the tab has to be at 8:00 or it will break off when started up. Far from UP or 12:00 !
So, I installed it at 8:00 because mostly it was very defined, of course mine is not working. !!! So....
Is that why? Not conclusive, It would be great to know the truth.

brooktre · Dec 4, 2019

Hang in there tysmobiletractor - I don't think it's you. I can see your other posts in "classic view", but not "modern view". I don't know why this happens but I've seen it on other threads on this site. It's a real problem because people can't see the entire conversation and this leads to some confusion.

Unfortunately I don't know the answer to your tractor question. The governor on my MF-202 tractor works, but it's not adjusted correctly. I'm hoping to look at it more closely, but have't yet found the time. Right now it has a miss and its' too cold to even work on that.

tysmobiletractor · Dec 4, 2019

Ok
Thanks.
At least I know I m not losing my mind.
I ll look at classic view when I have a chance.

I sent this post earlier. But it is mixed up in the order. Resneding:

Details are what I need to verify this.......
Any thoughts?...

Thanks
This info looks similar to other settings info for the linkage I've done already.
But for sure I will double check everything.

My biggest question is the umbrella that sits in front of the governor under the cover.
I'm suspicious that mine is installed incorectly and is causing the issue?
But I don't want to take it apart again unless I know specifics about its installation.

Does the tab on the umbrella go at 8:00?
Or UP?

I've heard if its wrong the tab breaks off and the govenor does not work!

What is the correct placement for this?

tysmobiletractor · Dec 9, 2019

Here is a pic of the umbrella as it sits in front of the govenor.
This was how I installed it.

The second pic is installation instructions that came with the new govenor. Problem is, there s no arrow to put in the UP position.

Any Thoughts on this. ?????

tysmobiletractor · Dec 9, 2019

Reason tells me to take it apart and move that tab to the UP position. But, I also thought I had it right the 1st time.

Any thoughts?

If the tab in UP is correct, why does the instalation video for this part from the selling company say it should be at 8:00?...
That is what's holding me back from doing it.

tysmobiletractor · Dec 10, 2019

Based on the pic from BIGRED showing #5 bumper stop, I think the tab at 8:00 should be fine. That tab should contact the bumber stop on its buttom side and hold the umbrella in the correct place.

Can anyone verify this?

brooktre · Dec 10, 2019

Both of my manuals say 8:00 o'clock is correct.

tysmobiletractor · Dec 10, 2019

Ok
Thanks! Very pertinent information for me on this.
So, now I move on to other details.

tysmobiletractor · Dec 11, 2019

Someone mentioned the bumper spring metal tab that is attached to the inside of the cover ( see #5 on earlier pic ) can be bent and cause problem...
Anyone have experience with this?

Thanks

tysmobiletractor · Dec 24, 2019

Here is a copy of paragraph from the manual submitted by brooktre:

RECHECKING GOVERNOR ACTION If no external binding is present and the governor is still in operative at 1000 RPM, the difficulty probably results from the governor bumper spring extending too far away from the cover assembly. This can be checked by disconnecting the governor lever spring from the governor lever assembly and pushing the governor lever assembly to the idle position. If while in this position, a spring action is noted, the governor bumper spring extends out too far and must be bent in towards the cover. This will require removing the front governor cover.

My govenor is still inoperable - I think this is the only thing left - remove the cover and adjust the bumper spring.
Anyone have this issue?

tysmobiletractor · Dec 27, 2019

OK, so I removed the cover and adjusted the bumper spring. It was about 5/16 away from the cover. I got it moved to about 1/8". Did not have any information to go on other than the manual says " must be bent in towards the cover ".

All, back together. Got it warmed up, and the same as before.
I have never seen the govenor lever move yet on its own.
I pulled the pin connecting the govenor control arm and carburator, and I can idle down the tractor, rev it up, and the governor arm never moves.

I can go back to adjusting all the linkages, but it seems to me that the governor is not functioning.

tysmobiletractor · Dec 27, 2019

Did a run of linkage adjustments again.
Govenor is definitely not working.
Tractor starts and idles nice. If you give it throttle it races up in rpm like crazy, govenor isn't engaging to compensate.
Linkage looks good, don't see any issues.

tysmobiletractor · Dec 29, 2019

Found the following info:

"Also, check to make sure there isn t too much play in the governor shaft. Too much wear in the shaft bearing can change the centrifugal force action of the governor. This causes it to compensate too slowly when fast response is required.

Replace the bushing or bearing if necessary. If additional internal repair or inspection is required, follow the instructions in your repair manual for governor removal, overhaul, or adjustment."

Anyone have an issue with the bearing or anything related to that, causing govenor problem?
Thanks

brooktre · Dec 29, 2019

Do you have a Massey dealer near you? You might try and talk to the service manager and see if they have a mechanic that knows these tractors. Or they may know another dealer where there is a resource you could talk to.

It seems like you ve narrowed your problem to the governor itself, but other than the manual I wouldn t know what to try.
