Servicing a Shimano HB-M756 front hub. I have a set of 13/15/17mm Park Tools SCW cone wrenchs. Two out of the three fit the cone and jam nut (don't remember which.) However, the wrench is too thick to fit the cone nut when reassembling the hub. That makes no sense to me. Any suggestions on a cone wrench that will fit? (I have googled and read every possible post...)
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Some Shimano hubs have the cone and it's wrench flats below flush with the dust seals on one side. So, if you remove that locknut, the flats stick up enough to unthread the cone but not far enough to take the cone wrench when the locknut is tightened down. You may have to disassemble the other end of the axle, replace and tighten the cone and locknut on the first side and then readjust and tighten from the other end.
