Took my rim to the shop today to get a tire put on. They also replaced the bearings on the rim, not the ones on the sprocket housing. When I put the cush drive back together and tightened everything back up the nut went beyond the holes for the cotter key before tightening up. This isn't the first time I changed tires like this and the nut has never went this far in. I took the wheel back off and everything seems to be ok. Ifanyone else has ran into this any help would be appreciated. Thanks in advance.
