Found a 9637D cast iron shift knob

Yooper Farmall · Feb 19, 2015

I recently bid on a rear wheel weight for $25, went to go pick it up and the parts dealer had 3 more. I picked up 4 in total for $25 each. I walked around the 2 Farmall H's he was parting out and saw a pto delete plate which I hadn't seen before, and also noticed one had a cast iron shift knob. It is stamped with 9637D but I can't make out an old IHC logo. I understand at some point during the war when rubber was in short supply they made cast iron instead. From a Google search, I have seen 1944's, 1945's, and 1946's with cast iron. I imagine not all came with them. It appears the knob is threaded onto the shift lever, I can't un-thread it by hand, I'll try some WD-40 and a wrench. I'm wondering if the rubber replacements are threaded or pressed on. If I did get the cast knob off, would I even be able to put it on my current shift lever?

I don't know how the cast iron knob is attached, but if you have the entire shift lever, why not just swap it out with what is on your tractor now?

I might just swap out the entire lever, I think only one pin holds in on. I need to find the measurements and see if this lever has any wear.
I think I would paint the knob black, but thinking they probably came from the factory red.

Don't take sand to the beach, I would paint the knob black,the rest red, and install it. Nice find! PS you better go back and give him so more money for the weights!

Rubber replacements just press on. I have a 43 H with the rubber knob and a 43 M with steel knob.

Seems like I remember that knob is threaded. Think at one time IH parts system listed it as a alternate that would work on a unthreaded lever if the lever was threaded.
Found in my note book some research done on M shifters. Best I could tell that knob and shifter could be on M factory tractors serial 60129 to 128006. Not the only shifter that could be used though. IH had a alternate shifter or two also.

Makes me think that folks are finally realizing that wheel weights are NOT made of gold.

I have a 1945 IH I-6 that has the cast iron shifter knob. I think it is threaded onto the shift lever. Never had it off.

The cast knob was screwed on. I have only seen one that was loose enough to unscrew.

There is a guy about 45 minutes away selling 2 weights for $75. I was going to drive to his place that same day until I found the 4 for $25 each.

There are two guys within 15 minutes with 2 weights they are advertising for $150.

And those guys wanting to sell 2 weights for $150 have probably been tripping over them for several years now.
