Century motor replacement

Hi,  I am trying to replace a Century B2748 motor on a PacFab/Purex Triton UltraFlow Pump System. I am at lost on how to remove the seal plate, almond from the motor mounting flange.I am expecting to see studs on the seal plate going through the through holes on the mounting flange. What I think I see is studs instead on the motor mounting flange. So whats holding the seal plate to the motor flange? I have hammered on the studs and the seal plate but nothings coming apart.

I am unable to load photos and not sure why it’s not uploading. I can send them if you can instruct me on the procedure or if theres another option, Thank You, Pat
