Last summer I was riding my John Deere 1959 530 around my neighborhood in lower gear (why I don’t know) when my tractor stalled and white smoke came out of the muffler and it looked like other places but it happened so fast I don’t remember. I did NOT try to turn the engine over at that time. Also, just after this happened, I spent two months in hospital and I have not been able to work on the tractor until now. I thought I had blown a head gasket but upon checking the compression I found I have around 150 on a cold engine. I assume the head gasket is good. I, being a novice at repairing John Deere tractors did notice when cranking the engine that the fan was not turning. So my question is “is the fan to turn when the engine is turning”?

I removed the governor and found that the governor shaft, part #B3781 R, is broken.
Do I buy a new shaft and have the bearings pressed on or buy a used governor?

Thanks.

I would

fix the one you have. Purchase a used one and you have a new unknown. Fix the one you have and you will know what you have with less worries.


Just what I would do.

I talked to a company yesterday about my governor. They said the governor and fan assembly need to match and they want $2500 to do the job. I MUST check other sources.

I would recommend getting a service manual for your tractor if one exists. Not sure if Deere ever printed one for the 530 or just relied on the "50" series manual to cover the 520/530 tractors too. The procedure for gov. and fan shaft repair and set up should be well explained in the manual. I have no experience with a 530, but think the gov./fan assemblies are similar to the late B tractor. The gov. gear to fan shaft gear mesh is very critical for longevity and minimal noise. If you can get a good used gov. shaft assembly, you would want at least the mating fan shaft gear from the same tractor. Or if the gov. gear you have is not damaged, it should be assembled to the new/used gov. shaft to match the original fan shaft gear mesh. The fan shaft assembly gets shimmed to adjust the mesh and gear backlash to the gov. assembly. A brand new gear set, if available, requires the same setup and shimming, but will not have a worn surface to contend with. Clear as mud, yes? lol
Check out Antique John Deere Parts replacement by Davenport Tractor for manuals, as well as Deere.

Do you have any pictures of the broken shaft? Was there any other damage? Could there be any broken pieces that have fallen into the crankcase?
Good luck with the repair. Sure would like to own a 530!

Hopefully I was able to attach some pictures of the broken shaft and of my tractor on general. The shaft break was clean.
I found one half of a snap ring when I took the governor off. I don't know where the other half might be. I see where one tooth of one gear is chi DSCN0940.JPG ped and the gears are worn.

Thank you for your help guys.
I do not feel up to repairing it due to health reasons.
Watch for it on Ebay soon. I don't know if whole or in parts.

Sorry to hear you don't feel well enough to continue. You gave it a good try though in finding the problem. Hope you can get healthy again.

tommyhawk-- All is not lost. I found the part. I do not know when I will get it back together. I am trying to figure out what caused the shaft to break. Oh, and I do have all three John Deere manuals.
Thank you for your encouragement.

The live hydraulic tractors are so much more complicated than an old B. I did have to rebuild the governor assembly because of bad bearings on our B. The fan shaft was also bad on the fan end. It was a labor intensive repair for me with very limited tools to do the job. Had to make spring compressor and puller parts, no press to work with.
I really don't know enough to help on the 530, but if the pump is directly driven by the gov. shaft, instead of directly from the cam shaft, you might investigate for problems there.
The 530 is a tractor I have always coveted but have never even sat on, except as a kid, at the dealer's lot. Got to run a 520 some as a teenager, but the 530 was one none of our neighbors owned.
Keep us posted!

Also on my 530 the manual steering is very hard. While my tractor is so far apart I thought I would Look into the problem. Any ideas as to the removal of the gear that is attached to the steering spindle? So far I have been unable to separate the two.

Pin between governor and powr troll.

There is a pin that fits in the governor case and I think it is supposed to hit something in the powr trol case. My question, is this pin has a groove on one end but not the other. Does the grove go into the governor case first or last?

Maybe this will help. I am not sure to what you are referring.

Thank you RandyM. To the best of my knowledge the pin does not show on either diagrams. I don't know how else to describe the pin and how it relates to both cases other than what I posted in the above post. I have the same diagrams as you but the governor diagram is for governors without a powr trol . It could also be someone forgot to but the pin in the diagram years ago. Hopefully someone else can help. Thanks again.

Todd, you are now in the territory of me asking for a picture of the pin and where it is supposed to go. Can you provide it? I am sure others would like the same info to be able to help you as well. You are possibly correct, an error in the publication. Sorry, just trying to set the ground work for someone that knows what you are talking about, for I know nothing of your machine. :mocking:

I found the pin on your diagram of the powr trol pump. It is item #8. Thank you for your help.
It was mentioned in the John Deere Shop Manuel.
