I've got the steering sector off the tractor. The reason for this is it wouldn't turn anymore. I've taken the sector completely apart. There was no metal shavings or broke parts, however the bearing that sets in the bottom of the gear sector was misplaced against the side of the box. I cleaned everything and put it back together. The steering sector worked, then when i picked it up off the bench this morning to show my wife it wouldn't turn . Does any one have some info for me I don't have four hundred dollars for a new one and don't see where I need one.
