Found out the problem on the 1945 John Deere B

Beatles65 · Jan 13, 2011

I went out to look at the tractor today and started it up. Started fine but then I heard that noise again so I shut it down. I then noticed that the fan blade wasn"t turning so I am guessing that that is the problem. It doesn"t turn at all even when I am spinning the flywheel.
What would cause this?
And, how hard is this to fix?
I was so excited to use this tractor this winter to shovel the driveway and it does a wonderful job at it. It has a 7 foot blade on the front so it just takes 2 passes to get the 200 yard driveway clear. My dad, brother and I used to just shovel the whole thing by hand.
Bummer!!!
Might have to awaken the 1948 John Deere A to do the job with the 7 foot blade thats on the rear.
I hope someone has an answer.
Thanks for everything!

The gears on the gov. and fanshaft are stripped. Probably a bad bearing in the Gov. caused the problem.

Check for ice in radiator.

There is a clutch on the fan, you can see the spring maybe something, maybe a dirt dauber nest, or ice has the fan caught. probably doesn't need a fan this winter.

You will just have to start taking it apart. And there is not much room to get the fan and shaft out without removing the hood and radiator. Maybe someone has a better idea. But oh, while you have it out you can get at the manifold if that needs a new gasket. they did not build those deeres to be easy to work on.

Cowperson, you'll be better off to give advice to the Farmalittle guys!

Years back on my A the fan shaft broke in half inside the tube, only made noise a little while but the fan didnt turn. More than likely its the bevel gears that turn the fan shaft. If I remember right you can take fan shaft assembly out the side. The bevel gears are matched set and after years of use they run together quietly, and should be replaced together. On mine I only replaced with a used fan shaft and gear, can still hear gears whine when alternator is working.

Yeah, help me out here. Something is broke. The flywheel turns but the fan does not. That don't sound like a fan clutch to me. The fan would at least turn some. I guess if it were me I'd grab the fan and see how much resistance there was. And YES, I've had several John Deeres apart. Is there a good way to get the fan shaft out?

There's no super easy way to get at the governor gears, but it's not that hard. Actually removing the sheet metal and radiator goes faster than you would think. If it is the governor gears they were available from Deere at about $600 a set. I know you should replace them as a set, but I have used ones that were in good condition, but not matched and not had any excessive noise. I would not try to use a worn gear with a new one, and I selected used ones that didn't appear to have any wear on them.Maybe I just got lucky.
Also check the right bearing bore in the governor housing as it has a tendency to wear oversize. Deere used to have a kit to rebore them, but I doubt if you could find one now. I have had to sort thru several used governor cases to find a good one. Good luck with it, it can be fixed.
