Tapping the Back of Crank
I was wondering what is the process when a builder hits the back of a crank with say a small hand-held type sludge hammer. Just wondering because I've seen this act more than once and was just wondering what exactly what this was accomplishying.
If you are a little lost, the short block is built, then the builder hits the crank a few times. Does this help the parts settle better or something?
I know silly question, but I had to ask. I've seen my builder put a 2-3" long steel sleeve on the end of the crank and wack it a few times along the outer edge (diameter) of the sleeve. I have also seen an iron block tapped on the back a few times.
