Having trouble getting the new one on. I lined the keyway up and even took off the cap to get a feel for the notch dropping in properly but I can't seem to push it in there. I obviously don't wanna force it or use a hammer. I thought to put the bolts on and crank them down and see if it would suck it down, but again I don't wanna force it. Should it be this tight getting it on, I thought maybe because of the new seal on it?
