Many years ago I picked up a book called how to hotrod engines. They built every engine avaiable at that time in doing so they gave tips that couold be used with any engine no mater what the make. This was so bizarre it has stuck with me so here comes the disclaimer ("I have never done this so I don't know if it is true or not!!!!!") but here it goes. If you want to keep your bearing from spining go to the drugstore and get some pure lanolin, as most of you know lanolin come from wool and is very slippery. But like with other things when it gets hot it's chemical make up changes and it becomes a very hard glue which according to the author is capable of helping keep your bearing from spinning. I hope this helps those of you who are pushing the envelope on your engines.
