i had trouble with one too. i heated it to temp and froze the cam didn't slide on either. i heated it with the rosebud tip and still had to drive it on. runout was w/in specs so i am running it. been fine for over a year. the net one i took to the machine shop and let them do it for $10. :rolleyes: it was a lot less stressful and i will live w/out the 10.
