Early style john deere B fan -

rockyridgefarm · Jan 21, 2015

I just got done taking apart my B to remove and repair the radiator.

I'm looking at the parts breakdown for a B and the parts from my B. They aren't near the same. Mine has a riveted housing filled with rubber. Looks like it used to be fused to an internally splined shaft. It now isn't and can be slid on and off that shaft with no effort. It slid forward and gouged a ring of holes into my radiator. Would I have any luck trying to re-glue it, or should I try to find another fan?

I am contemplating soldering or brazing the radiator's holes. The radiator core is in very good to excellent condition otherwise. Am I gonna have luck, or should I pop for a new $300 core??? I only paid 900 for the tractor...

This is a common thing to happen as the rubber hub degrades and fails. You can buy the friction drive style fan shaft and convert yours

If your are a competent solderer, you could
certainly fix it, or send it to a radiator
repair shop.

And even if you put in a new radiator, that
$900 B is now a $1200 one. At some point,
every old tractor needs a repair that may cost
as much as the tractor is worth. So what?

If you enjoy working with the old girl, that
shouldn't matter. And odds are you won't buy a
new tractor, or even a replacement, for less
than the radiator repair.

Thanks for the replies. I'm gonna try to solder the holes. If not, I'll get a new core. The little B ain't pretty, but it runs NICE.

Is there any way to re-glue the fan to the fan shaft? I'd be fine with replacing the whole fanshaft assembly if necessary (they're not expensive), but if I could reglue it, it'd save me some work. I don't want to try if I have zero chance at success.

Mine came off also and cut the radiatior. I had a guy fix the
holes at a radiatior shop. Get you a friction disc fan and put it
on your shaft. That's what I did. I bought mine on eBay.

I'm sure there is a space age adhesive out there somewhere that will hold but you are working with old deteriorated rubber that has gone soft and will give way again. If you do want to keep it original with a rubber hub you will have to get lucky finding a good used one unless there is a reproduction rubber one out there somewhere.
