I just put a TKO rear bearing and a fresh front bearing in a 7 port I am rebuilding and now when I put the crank in it is a little hard to turn. The rear bearing seems to be seated all the way back. Is it possible I messed up the race? It spins freely without the crank in. This was the first time I replaced a rear bearing. I heated the motor and used a wooden dowel and a small hammer to tap in the bearing. It did not go in easy. (new case) Any suggestions?
