I'm pretty sure of my terminology (per Google anyway). The worm gear I mentioned is "a shaft with a spiral groove meant to engage a gear" turned by the motor. The worm gear turned a large round gear that turned the furler extrusion. Mine are Leroy Somer MVA gearboxes.
I definitely agree with your lip seal comments. I'm not sure I can get mine out without disassembly. Are you able to remove them similiar to the C-Drive prop shaft lip seals? Using two smaller ones makes sense.
