Hope this new version lasts longer.

Also during replacement I noticed that the pulley appears to be slightly out of round. No vibration and the bolt is tight so I do not know what is going on there. (Jerry?)
I am also trying a slightly longer belt.

Just to be safe orders a backup bearing - it is very nice to have the spare in the garage.

So what is everyones experiences with the new 19k bearings? How are they holding up?
