1020 governor linkage adjustment

[jimmyO]

Hi all;
I have a replacement engine and a rebuilt carb on my 1020.
The governor is not adjusted nearly correctly. I advance the throttle from idle to about midrange until the governor responds, and then it revs up fairly high.
The springs on the governor are loose, and I've been told they should have tension on them at all settings.
I expect I have the linkage to the carb incorrect, maybe?
Does anyone have the adjustment procedure? I don't have access to the manual that might cover that.

As usual, many thanks for all the advice you knowledgeable people have provided!!!
Jim

Adjust the governor-carburetor linkage so that the lever on the carburetor throttle shaft lever hits it's stop in the "wide open" direction JUST BEFORE the governor lever at the other end of the linkage hits it's stop (also in the "wide open" direction).

I hope that's understandable the way I wrote it up!

In other words, the carburetor butterfly must be wide open JUST BEFORE the governor runs out of travel in that direction.

Hi and thanks;
I went to the barn and tried your suggestion. Various settings didn't change the result.
Somehow and somewhy, the governor doesn't smoothly respond to inputs of increasing speed, until about 1/3 or 1/2 throttle, and then the governor responds in a jump to what might be mid-range rpm.
I'm still suspicious that the governor springs aren't set right. OR, heaven forbid, the governor has to be removed again (after paying a lot of $$$ to have all this done!)

Was anything done to the governor?

That being said, in my experience (unless something important WAS changed on the governor) that many "governor issues" turn out to be "carburetor issues".

Was anything done to the carburetor?

Tractor carburetors typically have an "idle circuit", a "transfer circuit", and a "load circuit".

All must work together so there's a smooth transition from flowing fuel in the "idle circuit", to flowing fuel in the "load" circuit, and back to the "idle" circuit as hand throttle settings and load on the engine change.

Engine operation can be REAL erratic if all that doesn't work as designed.

 

[jimmyO]

Yes, I believe the adjustments are the problem. That's why I was wondering if someone could steer me to a procedure.
The carb was completely rebuilt since it wasn't functioning after the engine was replaced. I re-installed it and haven't been able to adjust it properly since.

Was the gov. removed from the tractor? I went thru something like this with a 1520 a year ago. Could not get the settings right and tractor wanted to over speed.I bought the tractor not running. There was a missing washer or the bearing inside the gov. housing.Pulled one out of a parts unit and all was good again.Just something to check. Tom

Why don't you have access to the manuals, service and operator's? Did you buy them after asking about the best ones to get back in the fall of 2017? I bet not. (I'm thinking you have the 3 cylinder 135 gas engine, you didn't say.) There is a John Deere 1020 OEM used service manual (SM2071) on eBay for under $80.00 or a CD for about $65.00, plus others. Pretty inexpensive for what you can get from them.

I don't disagree with looking for free on line, but if they can't be found I believe in purchasing them. Not having manuals after a couple months is just a pet peeve of mine, I consider manuals very important parts to have and make those my first parts purchases when I get a machine. If you don't know about the JD on line parts catalogs you can find your tractor's parts manual to use on line. Here is a link to it, if I got the right 1020: https://partscatalog.deere.com/jdrc/navigation/equipment/75128 .
You can't download it from there but you can print pages from it.

I did check the manuals, hard copies and electronic, I have and don't have one with that engine or I'd look at scanning that section for you, as I think you need to go through the whole set up. The 1020 is not in the 1000 series tractor manual, only the 1010s.

 

[jimmyO]

I agree with you very much about getting the manuals. I still have most manuals for a couple tractors I lost in a fire. I have most manuals for the replacement tractors. But after I bought this 1020 I had to have the engine replaced/rebuilt (didn't see that coming!), and after spending way too much ($10k) and other things going wrong, I don't have cash to put into more manuals. I ordered manuals for the 1020, and thought the service manual was in the batch but I was mistaken. At this point I'm just trying to keep things running. I've also purchased some things through this website for the replacements. When I can I'll get those service manuals. Till then I'm looking for answers.
Thanks.
Jim

I have the John Deere shop manual for the 1000 series tractors for sale. If you are interested shoot me an e-mail.

Not trying to screw the sale but here is a link to an on line copy of SM2033 for the 1000 series tractors for your review. It may work but the description in this one says it is for the 1010 series tractors (4 cylinder engines) as I posted before, That is why I didn't pass it on to you then, sorry if I was wrong about it not being ok for your 1020.

[jimmyO]

Thanks, I appreciate it.
You won't screw the sale if I can afford it. Lots of stuff going on right now, unrelated to the exported virus.

I'll look to see if it has what I need.
Thanks again.

Hmmm. I have the 1020 parts catalog, and the drawings match my tractor. The 1000 series repair manual has a number of governor linkage setups for gassers, but none matches my tractor.

Lots of other things in the repair manual are different as well.

Looks like I have to find the 1020 repair manual specifically. (I already have the parts catalog and the operator's manual.

Yes, you need the right manual for your 1020. The 1000 series (1010 model series) was an all together different engine than the 1020, I didn't think it would help you with your governor for that reason. I haven't found a free manual for the 1020. Do you have a local dealer? You might ask if they will print you a copy of the info to adjust your governor. Most have on line access to the JD manuals if they don't have a hard copy. Worst case would be they say they won't do it. I may be lucky but have been able to get some info from my dealer's service people over the years.

I've found a number of places to download what I hope is the correct manual. I'd rather order a nicely made printed copy (I'm older; my world is still 8 1/2 x 11). Until things loosen up I'll probably have to play and learn on my own. But that's not all bad either is it?
