I have a 10" Delta Rockwell Unisaw.  The model # is 83-631 if thats important.  The saw has been running great but was in storage for the past 8 months.  When I recently tried to use it I noticed the arbor seemed to have play in it and I noticed that the blade also was cutting a wider cut than normal.  I've made a  faint attempt to remove the arbor to replace the bearings, but before I did any damage I wanted to ask if anyone had any suggestions for me to remedy this problem.
