Hub cone compatibility-cone profile.
I was taught that when selecting a replacement hub cone the profile/curve of the replacement cone has to be identical as well as all the other fit issues. There are situations when a replacement cone with a different profile can be installed. The only reason that I can think of for suggesting never using a cone with a different profile is that it would lead to premature bearing failure. Can anyone confirm this and explain why or offer a different reason? Is it related to scuffing? Has anyone tried installing cones with a different profile and had good luck?
