I mean, you will not have enough room to get the bearings out, so if you unbould the liftcylinders, push up the middle section of mast then cross(as far as possible) the 2 liftcyliders and then lower the section, that should give you enough room for the bearings.
To take of the bearings you need a hammer and a tyre lever, push on one side and slam on the other side(hard if needed) Whatch out for the spacers (adjusting rings), you have to put them back again.
