Cam bearings | V-Twin ForumBarney Biker~~~ The reason there are two.....simply because if you are referencing the bearings that relate to holding the inner journal of the cam, ie· inner cam bearings....B168'.s in your case.....remember you own a ".TWIN CAM". ie· two cams with two journals = with each having a bearing thus = two inner cam ".needle". bearings....B168 to be replaced with two Torrington/Timken B168 bearings.
