Group, I finally got around to getting the High grade Idler pully bearings which won't wear out as fast. These are the ones used in special application alternators and other things. We call them Blue Seal,EMQ. The normal Black seal we have talked about several times wearing out to fast. Well try these. Walt, I'm sure can appreciate them. They are on the front page of the web site. John hervey http://www.specialtauto.com/
