Yes everything to do with that - here's part of an email that I received today from Tim Gauntt, Kelly's Director of Warranty and Tech Support
The looseness of the case is a mechanical issue on all the Ford style alternators. The way the housings are fitted to the stator allows for movement after the alternator is heated up and run with a load, something which we cannot duplicate in production testing. This is why you found the housing bolts loose but still safety wired. We currently affix a decal to the housing and recommend the through bolts be re-torqued after the 1st 10 hours of operation and then each 100 hours thereafter. It’s been my experience the 1st 10 hour re-torque and the 1st 100 hour inspection will be all that’s needed.
Here's a picture, sent to me by John Miller, a South African editor. It shows what happens if the bolts aren't torqued.
So if you have a Ford style alternator, make sure that you get the torque of the bolts checked as per Kelly's suggestions
