Ha! Brings back memories. I did a timing chain replacement on a friends Bonneville in a parking lot at the University of Minnesota, in the snow, must have been 1977. When we got it apart the nylon gear was completely stripped, and all the teeth were in the pan. No way to get them out. I told him we should pull the pan and clean it, and he said screw it, put it back together. Ran for another year like that before he sold it...
