<><><><><><><><><><> <><><><><><><><><><> Shane, Greg, Those are both great ideas on other ways to remove and install bearings. Thanks for sharing them with me and the list. Shane, one thing you didn't mention in your post is how hot you make the oven. When I use heat and cold I usually don't go over spit hot which is pretty close to 212 degrees F. For cold, well, the colder the better. And don't mess around with either piece when you grab them. Be ready to assemble immediately. A friend of mine does most of the sleeving of cylinders for shops in this area. He uses dry ice to pack a sleeve and a hot plate to heat the cylinder. (This is a very basic description) When he puts a sleeve into a cylinder he has about 10 seconds to make sure it's right and then it locks in place. The only way to fix an error is to cut out the sleeve and install a new one. Thanks again for your ideas and comment. I sure appreciate them.
