Farmall C Front Hole Size

Postby T-Mo » Wed Oct 14, 2020 5:58 am

Does anyone know what size the 3 holes (on both sides) in front on a Farmall C? I believe they're probably 3/4-10 UNC, but if anyone can confirm that I appreciate it. I want to add tie downs using a couple of these holes. See image below.

I just installed the factory snow plow on my SC and looking at the manual it says 3/4" x 2.5" (it was such a PITA to put on that I don't want to pull a bolt to verify)

Just try a 3/4" bolt and see if it fits!

I understand - when I removed the cultivators from this C last week - I was thinking, they're not going back on again unless they stay on permanently. I'm sure they're 3/4-10 thread - I'm asking here because I want to order some lifting hooks from McMaster Carr and it would be a good thing if I order the right size.

Thanks, everyone.

Now to a more pressing question. The seat pivot bolt was shot on this C. I bought a new one from JP's. Is there a trick to get the new bolt "squeezed" enough to fit between the seat mount? I'm sure it's supposed to be a tight fit, but getting it in between the seat mount isn't happening.

Doesn't that bolt go through some rubber bushings? If so, they may have been oiled and as a result swelled. If so they may need replaced, or possibly some rubber lube such as is used mounting tires applied to make the bolt slide through easier.
If you are not part of the solution,
you are part of the problem!!!

Yes, the pivot bolt is made up of two bushings, one on each end, a washer with the outside knurled, two bolts and lock washers, and a center section with both ends having female threads. The one that came with the tractor, the bushings were completely gone and the seat was just flopping around. I did get the new bolt in - I lube the bushings with a lot of oil and just forced the bolt in place. To be honest, the bolt isn't really a bolt, but the whole assembly is called a seat pivot bolt.

I picked up a new aftermarket steering wheel from JP's for $25, a better seat, a pivot bolt, and a throttle control lever from them. I will be making another trip down there once I get the necessities taken care of. Oh, and both rear tires are shot, one holds air, the other will go flat in a few days. JP didn't have any 11.2-36s, but I did find a free 11.2-36 on a rim, that was off of a 200. And it's in really good shape. That will be going on next.

I got part of the rear rockshaft with the tractor, but one of the mounting bolts is broken off in the rear frame. My first feeble attempt to remove it didn't go so well, so that will have to be address before I can mount the rear rockshaft.

In one week I got a free tire on rim and a free No. 8 Little Genius 2-12 plow. As the old saying goes, nothing is really free since I had to drive a bit to get them, plus the plow will need two tires.
