Doing a rebuild on a 1980 DT175. Cases are split and I tried to install a new main bearing after putting it in the freezer overnight then heating the case with a torch. The bearing went in half way and I hit it all the way in with a rubber mallet. It moves fine but is dry. If it moves OK when I lube it, is it OK? Should I have put lube on before installing it? What lube should I use?
