It appears that part 8603, the pulley, just slides back and forth and wobbles around on the shaft.
If it slides back and forth, either the hub assembly is not bolted together properly or the spindle bearing is bad.
As you can see in this illustration, the fan bolt goes through the blade, the hub cover, the spindle bearing and the hub. The bolts are secured by the 4 fan bolt retainers.
If it is bolted together properly and it still wobbles, the spindle bearing (#21A-8626) is bad. I went through this recently and found that there are zero spindle bearings available anywhere. I located a used fan assembly from a local guy, it was the last one he had. About that time I saw a couple of used fan assemblies sold on ebay, with the shipping they were close to $100.00

Harleymsn, you are so right! I did not have the retaining backing plates! You would not believe how many answers I got from so many supplier experts! I cranked, I bent the pulley so I need to find a complete minus fan. If you find one, please send link to it.
