The first roller I take loose when working on the tailgate rollers is what I call the tracking roller. It is the one on the lower back with regular hex head bolts in it and has slots in the frame to adjust belt tracking I think. Once it is out if you need to take the others out the belts will be loose enough. You have to put the tension release pins in before starting any of this.
On the rollers with the countersunk hex head you will probably need an impact wrench with a 1/2 hex socket. I have also had to heat around the bolt with oxy/acetylene torch before some would loose, even with air impact.
The last one I did I used a long rod (about 3/4'' dia) from a roller on a new holland round baler. A length of rebar would even work. I just use the rod as a long punch and drive the bearing holder out and then the bearing. Having a helper for this part is good. The bearings are the type that are made to use with a locking collar, but the collar is not used in this application.
It is possible that the bearing and holder might come out together, if so just press them apart once they are both out. Hope this helps and is not too wordy.
