It should be a 3/16" X 1 3/8" roll pin.

Here's a manual for your 702:

Yup a lovely roll pin that hasn't been moved I bet in quite some time. They do become a little hassle to get out from time to time. After you get it out, spray some PB blaster in the hole. Just because it comes out means you are only half way there. Majority of the time they are stuck to the steering shaft themselves. Be patient and persistent.........you can get it off without doing any damage.

I would find a piece of wire that fits through the center hole and clean out the inside of it, then put some lube in there and let it sit a while. PB Blaster or Acetone/ATF would be good. Kroil if you have it.

I have always had good luck removing steering wheels with a bearing separator.

:wave: Catman! Welcome to GTTalk! We're glad to have you with us! I used my hydraulic press (I actually bought it for this) to get the steering wheel off of my '58 RJ. The pin was also troublesome, but it came out with a little patience and a lot of PB Blaster. I'd love to see some pics of the 702 that you're working on as well as any other tractors you have in your stable at home! Thanks for signing up!

The roll pin holding the steering wheel on is more than likely rusted in so badly that it will be next to impossible to remove it without damaging the steering wheel itself. But there IS hope. Ask yourself why you want to remove the steering wheel from the shaft. If the wheel itself is in need of replacement then damaging it is not an issue. If you need to remove it so you can paint the steering shaft then the fuel tank can be unbolted from the console and the tank and shaft can be removed from the tractor together. The pin that holds the steering gear on the other end of the shaft will probably be much easier to remove so you can get the tank off the shaft. You can then mask off the wheel and paint the visible part of the shaft.
The roll pin is hardened steel that is harder than most drill bits. That means you can't drill it out. It is also very difficult to press it out without damaging the sterring wheel.
If you don't care about damaging the wheel you can remove the plastic that covers the area around the shaft by breaking it off with pliers, cutting it away with a die grinder, etc. then heating the end of the roll pin with a torch (you want as much of the plastic out of the way as possible so it doesn't catch fire). Heating the pin will remove the temper from it and make it easy to drill out. You will probably have to heat the end, drill out a 1/4" or so, reheat the new end, drill that out, etc. until you have gotten through the wheel and shaft. This is how I remove the pins in the early models that don't have plastic arround the steering wheel hubs. If you can find a carbide grit rod saw blade of a small enough diameter you can chuck it into a drill and grind the pin out woithout damaging the wheel. I've done this a couple times but the rod saws I used were over twenty years old and I haven't looked to see if new ones are still being sold. The rod saw needs to be of small enough diameter to go thrugh the center hole of the pin. You have to cut the eyelets off the ends so one end can be chucked into a drill and the other en can go through the hole. Placing a VEY slight bend, more of a light bow, in the saw and running into an out of the hole like a small cylinder hone will help control how it grinds away at the pin. That also keeps the saw from binding in the slit of the pin.
