The dowel in the front of my drive shaft broke the other day. I was looking all over for a 1/4" x 1 1/2" dowel.My lousy local Cub dealer had nothing and didn't even know if he could get one, and neither of my local hardware stores had anything. I bought a grade 8 1/4" bolt and went home to see what I could do. I found what looks like the remains of a brass door hinge pin under the tractor where it stopped driving (luckily just outside and up hill of the barn door) and some more of it om the pan under the drive shaft.

The shaft and cup are worn enough that I was able to get the 1/4" bolt ib there and put a nut on it.

The tractor drives OK now but I know that there are some parts that have to be replaced. The drive cup and flywheel have a bunch of play in them. Click on the picture for a video.
What parts do I need here and how involved a job is this gonna be? I figure that I will need the drive plate, flywheel drive, maybe a flywheel, and drive shaft? I am not clear on how I would get to these parts either. Split the tractor? Remove the engine? Please let me know what I an getting into here.
Thanks
