Overtightened accessories belt damaged crankshaft&bearings ?

IS it likely for an overtightened belt to damage the crankshaft bearings, I ask because I've heard grinding during acceleration always below 20 mph from a cold start and felt shaking when sitting idle half a dozen times in the 5 months since the belt was overtightened.
I ask now because i just noticed the main seal on the crankshaft is leaking and the grinding sounded like little ball bearings being ground down by a big metal bar.

Seems to me the alternator/starter pulleys would of dealt with the brunt of the added resistance, not the crankcase. For all I know, the seal on it has been leaking for the last decade. dont even have a check engine light just the grinding sound irks me.

No, the rubber belt won't be able to apply enough force to the crank to damage it. I think the leak is a coincidence, and the sound is more than likely a failed timing chain tensioner.

That being said, the last clutch job I did (a '97 Ford Escort with of all things, a failed pilot bearing), the puller tool didn't fit very well through the bearing race. I had to basically pack the bore with grease, then use a wooden dowel that just fit the inside diameter to pop it out.
