Great video! I never saw inside a Roll-O-Matic. Your repair of the bad threads was a good idea!

Yes, I had never seen the inside of a roll o magic. So I figured there would be others out there in KZbin land who hasn't seen the way they operate either.

If you get the Roll-O-Matic reassembled correctly, both sides will stop contacting the positive stop at the maximum roll. If they are one tooth off, one side will not travel far enough to contact the positive stop. If mine ever had a punch mark, it was very light and got worn away over the 50 + years of hard farming, so I had to experiment a little.

I totally understand what you're saying. Without the "timing" marks it would be really hard to tell if you've got them installed correctly.

FYI: another trick to getting g broken off bolts & caps is to buy a set of quality HSS or Colbalt left had drill bits. Also if you have access to a mill, take a small carbide endmill to flatten the tap surface, then slowly begin drilling counter clockwise

I've heard of people doing that. But I think the only way to drill out a tap would be to use solid carbide. In my video where I got my 830 running I show how I made a drill guide to use a hand drill and a carbide twist drill bit to remove a broken HSS drill bit while on tractor.

Your model A, I believe, is a model AN. If it were me, I would keep the Roll-O-Matic front end on only long enough to get the narrow front fixed to keep the integrity of the AN, seeing that they’re comparatively rare. But it’s your tractor so do with it what you will, just a suggestion

I've always liked the single front ends. I'm sure I'll put it back on. I'm interested to see if there is any difference in drivability with the roll-o-matic. Primarily when it comes to steering (steering my tractor with the single front tire is very hard) and front end bouncing up and down in a rough field. Also, when driving with the single front tire, you can not see the tire at all, so the double tires will be different. Like I said...it will just be fun to have the roll-o-matic. Kinda like getting a new tractor for a tiny fraction of the cost and effort. Ha!

They do make tap extractors. For removing broken taps. They don’t always work but it might get that tap out with some heat from a torch. I have used a chisel to break them apart but I used a torch to get it real hot first. A torch might not be such a good idea on old cast iron like that though

I have never seen a tap extractor successfully remove a broken tap. The little tangs always seem to just break off.

Where are you ordering your front tires from? I like to replace mine on my 1951 JD "B"

I bought mine on eBay. Seller's name is tiresave. They are actually a little cheaper now. www.ebay.com/itm/171829260232?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=kWHGx30GSla&sssrc=2349624&ssuid=N-yBO4m-Tam&var=&widget_ver=artemis&media=COPY
