I’m replacing the rear housing bearings on my sons machine. I got all the parts and when I put in the new bearing cups, bearings and seal in the new housing there is room between the bearing and seal. Should this be like this or should I have only gone part way with the new cups so the cup, bearing and seal are all snug? I would think you should drive the cup all the way to the lip inside the housing but this room has me wondering. Any advice would be great!
