No, apparently where the "male" end of the starter assembly slips into the "female" portion inside, there is a little protective sheath that sits inside the "female" end and the "male" slips into. Well to get to the point, in my efforts to re-seat it, I must have slightly distorted this sheath and I tried to bolt it in anyway - thinking that it would just slip back into place. WRONG!! Oh well, it was a fun learning experience, but I did too have a little trouble with the O-ring when I got my new cover but just a little prying with a blunt object on the O-ring (so I wouldn't cut it) helped that. Oh yeah, the service guy at the cycle shop just smoothed down the portion of the sheath that was affected and no problems after that.
