I took a dial apart once. Most probably it is not in the dial at all. Dials don't do much other than try to turn parts that are gummy. You will need to oil every single moving part you can find - trace from the dial all through the machine. Give it oil. Turn it on every side and run it or turn what ever turns. I would use a little denatured alcohol or kerosene to remove dried on grime - keep off the plastic parts with solvents. Then reoil so it doesn't rust.
