Hi JEB, The doors are installed before the final trim is put up, so therefore, you will need to remove the head and side casing as well as the head and side jamb from the "access" side in order to remove the door. The rollers install from only one way, so look up to the track and see which way they should come off. Many times, the installers put these pieces up with screws, instead of nails for future access. You may want to do the same when reinstalling the trim. Slice any caluking around the trim and use a flat pry bar to assist with clean removal of the trim. Good Luck.
