HD dosen't give a rats *** about your trouble, knowing they know there is big problem with both bearing.. i wrote in this fourm way back and explained issues as to what to look for. as to the failure of mainshaft bearing i'm still at wits as to why they fail.. the primary bearing it's explained why. i even connect *** bearing corp. that makes mainshaft bearing for HD . they don't give a crap either. so to sevice my memory right, look up in this forums search 6 speed transmission failure or mainshaft failure. or something like. it explains what i personally had repaired 4 harley mainshaft bearing on 4 different bikes all 6 speed and the failure of bearing wear pattern are all the same.. if u read that one u found right article.
