I'm afraid the motor company is at it again folks. They switched from the tapered Timken that they have used since 1955 to a caged roller on the sprocket shaft bearing on all big twins and sportsters and they started this in 2003. The information that I have read is that it speeds up production because the new bearing does not require end play set up.(trying to save a buck! but at who's expense?) The info also stated that several failures have occured in high-output engines but stock engines seem to be just fine. There seems to be some concern about the new screaming eagle engines because the engines that have failed are close to the dyno numbers of the 103!
