<VV> Mysterious Loosening Generator Pulley Nut

[cwiland at zzz.com]

This has happened twice to my Spyder's generator. This last time I had  
about 200 miles on the engine/generator. Both times I installed a new  
key, cleaned the armature threads with acetone and installed the  
pulley with Loctite on the left-hand nut threads. When everything is  
secured I can feel a slight amount of play between the armature shaft  
and drive end ball bearing race. Could this set a vibration and work  
the nut loose? Anyone else have this problem and solve it? The  
generator has about 14000 miles on it since I rebuilt it with new  
bearings and brushes and it has the correct fan/pulley for a Spyder.
