Most just hammer them on and go, I have used loc-tite and have just hammered them on, didn't make any difference either way. Clean and smooth the yoke seal surface best you can, the smoother it is, the better the sleeve will go on. I've had to buy two sleeves when the first one got stuck 1/2 way, a press would be good to have or threaded rod, washers, and a couple nuts to press it into place. Some go on pretty easy, some will fight you.
