Bearing on Belt Tension Arm Roller, Vermeer 554xl

Bearing is out on the belt tension arm roller. From what I can tell, the bolt goes into the roller from the outside of the arm, so not much space between the baler wall and arm/bolt, does anyone know how I access it? I have read that for some balers you can take the belts loose and then the tension arm can be raised up high enough (with a hoist or front loader) to access the bolts on the end of the roller, is this true for the 554xl? Any tips on breaking it loose or this process?

I am 60 miles from the shop, so I would prefer to change this myself, or at least just carry the roller to them once removed.

Thanks in advance for the help.
