The o-ring is there to stop the outer race from turning with the inner race. I have left the o-ring out on many occasions and not had an issue. Either way make sure the bushing slides freely before you put your engine back together.

Just some quick questions about JetJoe turbines:
1) What do you look out for regarding the condition of the bearings?

Many thanks,
