Thank you 4Salt, DrifterWA and Chuck S !

Plan now is to buy a new liner (wear ring) and a puller , or couple of pry bars. Heat the impeller shaft and pry off the impeller...

Still not too sure about the grates. I put Liquid Wrench in the holes and let it soak for half an hour then pounded pretty damn hard with a fairly heavy hammer with no luck. Thinking about taking it to a pro to have them get the pins out....

We want to do as much of this as we can ourselves, mainly so we learn how to do it in the future.

Thanks again for all your help guys, I really appreciate it....
Dave
