I guess your machine has been modified from the original- in your Tree diagrams there are/were contactors that pull for forward and reverse which are powered by the step down transformer. Sounds like your setup is different now
Seems like if it ran before on 440 it should run on 220. Are you sure the motor wires and drum switch are configured correctly?
I suspect an issue there, rather than a bad motor. Just tryin' to save you some money

ps what is your 3 phase power from? Do you have actual 3 phase coming in or are you using a VFD or RPC?
have you tried bypassing the drum switch and running power direct just for a test?
