Runaway

Dad"s 130 is running away. I can manually tug the linkage to the carb and get it to settle down but as soon as I throttle up she won"t come back. Two questions for the wise: I"ve disconnected said linkage. Should the bit off the governor return towards the operator when I pull back the throttle? And when I take off the governor after supper is anything going to fall apart?

I"ve got the 140 sitting next to it, it"s running like a top but I"m a little unsure of what he action in the governor is supposed to be. At mid throttle position there is about three quarters of an inch towards the front of the tractor and it is quite heavily sprung. But the action back to the operator is very soft on both tractors. But non existent in the 130. I can"t actually see what"s doing on the 140 because the alternator is partially in the way

Hopefully the situation makes sense. I think I know what"s up but looking for feedback before I open the governor.
 
Could be several things inside of the gov. Thrust bearing is froze on the shaft and the spring that holds the gov gear in place on the gov shaft broke or stuck spring binding. Is the input shaft loose from side to side. Is the linkage going to the carb free to find that out you will need to remove the clevis pin on the out-put lever to see if it travels free. Dont remove the gear that drives the gov or you will be out of time. If you need to remove it carefully mark where the gear meshes as it does drive the dist.
 
Thanks. Don't think it's ice because we just went through a nice thaw and I had the heat on all day in the shop.

I've got the linkage to the carb apart. Just not sure what the action on the output side of the governor should be when I pull throttle back.

Is there any point to making the linkage to the carb longer. Could that save me opening the governor?
 
Just went thru the same thing on a 100. Would start and idle fine but when you gave it some throttle it would go wide open and then some. The linkage on the rod from the governor to the carb had lost the pin through the hole that holds it in all the way and even though it was still connected it would back out just enough to bind and nit let it work. when you worked it by hand it would do fine. May nit be your problem but something you might check before going into the governor. Mine was loose on the carb end.
 
S MacKay; When I saw your name as poster I thought "that's Hughies son Sandy." I miss your dad's postings on this board. Good to hear you call it 'supper'! Please greet you mom and family; hope all is well. Good luck with your project and post back your results.

No. The carburetor and the governor must be properly "timed" for proper operation. Making it longer will just change the position of the throttle lever when it runs away on you.

Taking the governor off is no big deal. I've done it a few times on a Super C which is the same engine.

You just need three different 1/2" (IIRC) wrenches to get at the various bolts. Shallow well socket, deep well socket, and combination end wrench.

Keep track of where the bolts come from.

Nothing is going to fall out, except maybe broken pieces of spring if that's the problem.

Usually the problem is either the thrust washer on the shaft, or the spring inside the housing. Just to be safe replace both.

To time the gov. and carb., TRACTOR OFF, unhook the clevis from the rod going to the carb. Push the throttle lever to full. Now adjust the carb rod until the pin will slide through the clevis and governor arm easily, with the carburetor pulled to wide-open throttle.

If it worked before you shouldn't have to adjust it much if any. If you have to adjust it a lot, STOP. Something is wrong, or you're doing something wrong.
 
Yes and yes. Got it apart, not much wrong except way too much water and chunkies and perhaps needle bearings the assembly rolls on are trash. The neoprene sleeve between the bearing and the gear is shredded on the gear end. I'm saying the thing was frozen pretty good. It was pretty flipping cold last week.

Anywho, my diagnosis: not enough oil changes.

Thanks for the advice all.
 
Is this Sandy of the famous MacKay family? My wife and I stopped to see you and your mother in Sept 2011. Your mother"s cookies are the best!
Please say "Hi!" to her for us and we hope all is well with you and yours.
I am glad to hear you are enjoying & working on your dad"s tractors. Are you on this board often?

Had a similar issue on a BN one time. Ended up being the arm on the end of the carburator butterfly throttle valve shaft being loose.
 
Hi Lowell, it is I. I don"t spend enough time here. When you have a problem with an old farmall this is the place to go. Hope you are well.
 
I recommend that you replace the thrust bearing and the spring while you're in there whether you were planning to or not. I had to take the governor apart an extra time because we only replaced the spring.

I said it wasn't difficult. Never said I enjoyed doing it...
