has anybody ever experienced an armature that drifted in the case causing problems?
I can't get the pulley off (I've never been able to pull one of these off) but I can tell the drift is caused by some sort of circular retainer drifting out of the front of the case (on the inside, drifting toward the center)
I was able to push the retainer back in with the curved arm of pliers for a wedge, but I have no idea how likely the retainer will move again or not.

Just wondering if anyone has ever dealt with this. It's a very nicely chromed case so I don't want to toss it.
