F-12 WHEEL SPOKES

[xsurveyor]

Would anyone know why 3 of the spokes on the steel wheels of an F-12 be longer than the others and have a hole nearer to the axle?
Also should these spokes be mounted toward the inside or the outside? Thanks.

I don't concerning which way the wheels go on if the hubs are outside or inside but I have them mounted to the outside on my F14 and I can't narrow up the wheel enough for my plow. Someday I've got to turn them around.

Not sure if spokes are replaceable if damaged, such as being bent. I would presume they would be. Maybe was replaced with a spoke from a different wheel that was longer. An extra hole was drilled to accommodate the rivet, and spoke was not cut off, and just left long. Just a guess, or there might be some other reason.
The wheels can be mounted either way. Clamps in or clamps out. Wheel width can be made wider with clamps mounted inward. Wheel width can be made narrower with clamps mounted outward. Me personally, I don't like the looks of the wheels when they are dished out and clamps are on the inside. So unless I needed the extra wheel width, I would not mount em like that. On another note, if axel load is an issue, the closer the clamps are to the axel tube, the less strain their is on the axel. But it is rare for someone to find themself in an axel load situation.

The parts book is interesting. For tractors FS 501 to FS3750 there are 16 short spokes and 16 long spokes to the wheels (half each). For tractors FS 3757 to FS 81597 there were 26 short spokes and 6 long spokes (i.e 3 per wheel). For tractors FS 81598 up there were 32 spokes (I presume all short).
It might be interesting to see some implement manuals to see if there was anything connected to the inner end of the long spokes. Unfortunately the only ones I have are for the 215-H cultivator and the 12 mower and they do not show anything.

the three long spokes are for a sprocket that is used to lift the mounted plow. They are on the inside to lift the plow.

Well, not sure how many different models of mounted plows there were for the F-12 and F-14, but here is how my mounted plow lift drives:

My F-14 has those extensions on the rims as well. I always thought there were for mounting wheel weights. I don't know that for sure, but that was my assumption on them. I bought my F-14 from the original owner's estate, and those were facing outwards. Not sure that means anything, but that is how I got it.

Looking at the pictures more, I guess I can see how the drive sprocket could bolt up to those. It has 3 legs on it. Seems a bit restrictive to me, as the wheel base would have to be set and left to correctly line up the chain. However, that doesn't mean it wasn't used for that. It would definitely be a narrow wheel base if that's what it was used for........

I absolutely don't know for sure, just sharing thoughts and observations.

Hi Tom:
Thanks for your reply. I think your answer to the question makes the most sense of all the replies but it has me thinking
that these flat spokes would not work for heavy equipment like a plow lift due to the weight , etc. That is probably why your's appear
to be made of heavier cast iron.But it has given me the idea that possibly some type of chain drive gear attachment to drive maybe a corn
grinder or fanning mill or such lighter equipment with the rear of the F-12 elevated off the ground. Like you I am just speculating until
that one guy that really knows informs us. Thanks again ! (P.S - do you have any tips for me on this money pit I am working on?)

Hi Plowboy:
Thanks for your reply! Do you actually use these extended spokes for lifting a plow? As in my response to Jim I wonder if these flat spokes
would be heavy enough for such heavy lifting.Take a look at his plow lifting attachment made apparently of cast iron. Still not sure but
any answers are welcome. Thanks . Rich.

Look in PO-2 plow Parts Catalog at the No 90 tractor plow.
it lists 3 sprockets to lift the plow.
PO-1850A sprocket is for the tractor with forged steel hub and 3 long spokes.
There is a picture of it on page 153.

Thanks Jim. Like I said, I was not sure, and I have only seen the setup that I have with the cast iron sprocket and axle hub.

Good stuff. Learn something everyday!
