I just rebuilt both my front and rear hubs with new bearings etc, after I was done I noticed that in one of the three books I have it says to "put the small end in first" or down I don't remember. When talking about thar tube spacer that you push aside to get the bearing out. I am puzzeled because I don't remember one end being smaller than the other. The factory 850 manual doesn't say this and the one that does is the old Chiltons 750/850 pre MKIII. Did I just not see that one end was smaller in some way or is that book mixing info on years. It was in the section for "Cush drive"??? I'm hoping I don't need to take it apart again to check!!!
