Massey Ferguson 31 sickle mower wobble box removal

[Flyman59]

I have a MF 31 sickle mower and the bearing behind the pulley on the wobble box is shot. I may have access to a parts mower with a good wobble box. How hard is it to change out the wobble box versus changing the bearing if the bearing is even available? I haven't had a chance to look at it closely yet to see if the box is removable. Thanks in advance for any help.
