Well many hours later and a trip to Advance for a pulley remover, I have the shaft separated from the lower wheel. Reading Ethan's post I tried to find bearings with z or zz and I am having no luck.
The bearing numbers to get started on the lower wheel shaft are 87506 and 87505. The bearings on the shaft seem to be in good shape but since I'm in the middle of all this surgery, I might as well put new bearings in the saw.
My big challenge will be finding a retaining nut to hold the shaft in place in the front. I can't believe the person who took it apart forgot to put it back in?? The cost of the part new is unreasonably expensive. Maybe he thought the heck with it and we'll see if this works.
I would like to get the part some way.
Any recommendations are appreciated. I am having a little search frustration trying to find the used parts section of the OWWM site. I'll have to work on that tomorrow.
Here is a photo of the trunnion that hold the shaft that the lower wheel is attached to. On the back of the shaft is the large pulley driven by the motor. Its very hard to see but there is threading at the very beginning of the opening. The bearing sits in the little shelf and is stopped by the next step. To keep it from coming out while in motion there needs to be a large nut that screws in the threads.
The photo below is how I spent my day. Snug the pulley, tap the head of the compression bolt resnug the compression bolt. The whole time praying you don't crack the aluminum wheel.
I have had some horror stories doing old Peugot brake drums but this one is the gold medal winner. What a pain in the a$$
The puller would not do the job without tapping on the long bolt several times than tightening with a wrench to move it 1/32
Its done and I am on my way to get some ice and Dr Dickel.
