How to remove 90 year old taper pins
  • Do this outside, or in a well-ventilated area.

  • Take a heat gun and blow heat on the part for about two minutes to get it up to maximum temperature.

  • Spray the part with penetrating lubricant. It will smoke slightly, and it won't ignite.

  • If the lubricant evaporates, spray some more on, until the lubricant shows no sign of evaporating anymore, meaning that the temperature of the part has dropped significantly.

  • Repeat the heat - lubricant cycle three more times.

  • The idea is to break the bond between the taper pin and the part, and get some lubricant in the tiny microscopic gap in between.
