rebuilding heater blower motor

[GoMangoBoys]

Our blower motor for the heater does not work at all.  It reads as an open circuit.  I have the bolts out, but it is a little rusty.  I am hitting it with PB Blaster.  I tried tapping it apart with a punch in the indentations on the sides, but it did not come and I did not want to get too aggressive with hitting it.  Any suggestions on getting it apart?
Thanks

Send it to Topher McGinnis. He has mine right now. Very reasonable and will look and work like new.
