Anybody have an illustrated parts breakdown on the mandrel itself?

I was mulching leaves when I heard this awful squealing, metal on metal sound coming from the mower deck. I thought it would probably be the bearing in the idler that dried up and gave up. I was wrong. The pulley on the outboard spindle mandrel is loose on the shaft and I found a woodruff key that looks like it ran into a grinding wheel on multiple locations on this key.

I need to know how this mandrel is assembled. Help please!

Thanks, Steve with a boat-load of leaves ready for mulching and a broken mower deck.
