I'm servicing the hub on my MC28SP. I've found some issue with parts on this. In the Japanese service manual and a VFR400 English service manual, it shows a collar in between the double roller bearing and the outer dust seal. I don't have this in my hub and as I've owned this bike for over 20 years, I doubt the hub has been apart.

Also, it shows an inner dust seal on the needle bearing side. Its definitely inside my hub. My Honda MC28 Japanese parts list shows neither of these parts. Anyone have insight on this? Much thanks, Scott
