IH 91 sprockets for Soys

According to my notes, you need:

6104444R1 = 43 TOOTH

610934R1 = 35 TOOTH

610935R1 = 51 TOOTH

I think this will give you a cylinder speed of 578. Not sure on that.

The locations are listed in you owners manual. Otherwise, you can figure out what goes where by using the pitch diameter of the sprockets, and which are the driven, driver, and idler.

You will most likely have to purchase some "blank" sprockets with the correct number of teeth, and then bore them to size, and drill the bolt hole pattern. I looked for all of the above mentioned sprockets years ago, and all were NLA. Maybe a few have turned up since then.

Best of luck.
