How to Remove a Shimano Crankset


Powered by the legs, a bicycle crank transmits motion to the chain, which in turn rotates the rear wheel, propelling the bicycle forward. A Shimano crankset includes a pair of crank arms, one on either side of the bicycle. With the standard Shimano Octalink design, the arms are mated onto the ends of a rotating spindle and held in place by crank bolts.

Things You'll Need

  • Bicycle work stand (optional)
  • 8 mm Allen key
  • Pin spanner
  • Crank puller
  • Adjustable wrench
  • Secure the bike in a bicycle work stand. Otherwise lean the non-drive side of the bike against a sturdy surface such as wall. To prevent marring the bike, use a smooth surface.

  • Locate the dust cover ring around the crank arm bolt on the right, or drive-side, of the bicycle. The dust cover contains a set of small divots called "pin holes".

  • Insert the tips of the pin spanner into two of the pin holes. Rotate the pin spanner counter-clockwise to loosen the dust cover. Remove the dust cover.

  • Use the 8 mm Allen wrench, and turn the crank arm bolt clockwise. Use the opposite Shimano crank arm as leverage when loosening the bolt. Remove the bolt.

  • Thread the end of the crank puller tool into the center of the Shimano crank. Use an adjustable wrench to fully tighten the crank puller.

  • Turn the handle of the crank puller clockwise until the tip of the crank puller contacts the spindle. Continue to turn the handle. As the handle is turned, the crank arm will begin to separate from the spindle.

  • Use the adjustable wrench to loosen and remove the end of the crank puller tool from the crank.

  • Pull the loosened drive-side crank arm from the bicycle. Turn the bike around, and repeat the steps to remove the second crank arm.
