MG Midget and Sprite Technical - Armature sundries

I could buy a NOS C 40 dynamo armature for my toasted one on E-bay. It was toasted for several reasons:
Corroded screw connector on the control box
Bigger demand (headlamp relay�s and 2,5 mm2 wiring)
High RPM during hours
Lat but not least, the open ring on the pulley side of the armature was gone (photo). I suppose that too much torque on the pulley nut forced the open ring out of its grove. So the armature scuffled against the dynamo and several wirings were interrupted.

Question:
Is the open ring in the armature enough to withstand the torque of the pulley nut? Or do I need another closed ring over the open one to prevent it to be pushed out of its groove?
