First time servicing a rear hub for me. I disassembled and cleaned my Shimano FH-M510 rear hub, removing the nut, washers and cone only from the left side of the axle. When I went to insert new bearings and grease I noticed a silver ring, and i don't understand where i have to put it (you can see it near the old freehub body).
Did I put that ring with axle's parts by mistake? I just remember to have cleaned it from grease. Can someone help me? Thanks
