Message: [QUOTE="Ol'89r, post: 1249239, member: 17212"] Why would you not heat the cases? When you drive your bearings out of the cases without using heat, it removes a little bit of aluminum from the bearing boss. After you do that a few times, your cases become junk. Go the your local hardware store and buy a butane or propane plumbers torch. They are very inexpensive. Heat your cases to about 350 degrees or until you can sizzle a drop of water or spit on the cases. THEN, remove or install your bearings. If you seal your bearing in a plastic bag and then put it in the freezer for a couple of hours, the bearing will fall into the bearing boss without having to beat it with a hammer. The heat expands the case and the freezer shrinks the bearing. Do it right. :cool: [/QUOTE]
