Well I got the engine pulled for the clutch on the tractor. It has a s 2 speed like a cast iron automatic on the back of it that hooks to the transmission with 2 sprockets and a chain coupler once it is in the frame. Those parts were worn so I got 2 new sprockets and chain to replace. I found it has a spanner nut holding the one on the 2 speed and the other on the input floats. I had to order the spanner nut and seals with a socket this morning. They said they have the parts and will go out UPS Monday so I am on hold till Tuesday when they arrive.
