Its been a long time, but I think you only need to remove the collar if you want to replace the bearing or if the collar has a groove worn in it, which is often the case. After draining some of the differential oil and removing the 4 bolts from the PTO housing you should be able to pull out the shaft and PTO housing. By removing the retaining ring, the shaft and bearing should come out of the housing. The seal should be in the housing and you should be able to use a hammer and punch to drive it out. If you do need to remove the collar, by having the shaft so there is a support under the collar, use a cold chisel as if you are trying to cut a groove along the length of the collar. This should swell the collar so it can be removed. The new collar must be heated with a torch, not quite to being red, so it can be installed. Before installing, check the outside diameter of the new collar to see if it is the same as the old one. This is true of the seal inside diameter also.
