So today I was forced to install the new 19000 rpm bearing.
The last replacement from NAPA burned to a molten glob today.
Strange thing is I was pulling in to a parking lot when it seized, so it was not even working hard.

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?
