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
