Hey everybody. I tried posting this on another forum and got no replies. Hopefully someone can help here. I have the crankcase of a 07 400ex split and stripped of all parts. I ordered all new bearings and 2 of the bearings are not smooth at all. They are part #s 91006-hn1-a41 and 91004-hn1-a41. They are sealed on one side and goldish in color. They also have a different center than the others. Anyone that has been in there knows what i mean. They go to the transmission. Anyway, I ordered replacements and the second set does the same thing. The ones I took out of the case were smooth as glass. Only explanation I can think of is they were sitting in oil? I don't want to reuse the old ones. Do these sealed ones loosen up or something? Thanks.
