How to Remove a Clevis Pin


Clevis pins provide a strong joint between two or more pieces of equipment while allowing the joint to pivot. One end of a clevis pin has a flat head and the other has a taper. The tapered end aligns the holes in parts as you drive the pin into the parts. A hole in the tapered end of the pin holds a cotter pin. This keeps the clevis pin from falling out of the pivot joint. However, corrosion and pressure often make it difficult to remove a clevis pin from secured parts.

Things You'll Need

  • Penetrating oil
  • Needle nose pliers
  • Pry bar
  • Drift pin
  • Hammer
  • Self-locking pliers
  • Spray penetrating oil on the visible length of the clevis pin. Allow the penetrating oil to sit on the pin for five to six hours.

  • Grasp the circular end of the cotter pin (located on the tapered side of the clevis pin) with a pair of needle nose pliers. Pull the cotter pin away from the shaft of the clevis pin. Set the cotter pin aside.

  • Insert the flat end of a pry bar under the lowest part of the pivot joint. Push on the end of the pry bar to release pressure from the clevis pin shaft.

  • Align the tapered end of a drift pin with the tapered end of the clevis pin. Hit the flat end of the drift pin with a hammer to drive the drift pin against the clevis pin. Continue hitting the end of the drift pin until the clevis pin pops from the secured parts.

  • Grasp the flat head of the clevis pin with self-locking pliers. Pull the clevis pin away from the part while twisting the pin in a circular motion.
