Crank Removal for Park Tools

Park bicycle tools are instantly identifiable by their blue handles. On the tool board at the local bike shop or in the hands of a dedicated do-it-yourself cyclist, Park tools offer durability and value. As bicycle components have become increasing specialized, Park has met the demand for maintenance tools. Crank tools are largely divided into square shafts or spline shafts, and shops or home mechanics will often need both types.

Self-Extracting Cranks
- Some cranks are equipped with a self-extracting bolt assembly, with a retaining ring that looks like a dust cover installed into the arm. Do not remove the retaining ring. Simply turn the bolt out counterclockwise with an 8 mm or 10 mm hex tool to remove the crank. These cranks are offered by Shimano, SRAM, Truvativ, FSA and Race Face.
Park CCP-22 for Square Taper Cranks
- Remove the crank dustcap to reach the bolt. These bolts are usually 14 mm and must be removed with a socket wrench. Be sure to remove the washer under the bolt, then thread the CCP-22 in place. Be sure to turn the center extractor fully counterclockwise so the outer body will thread fully into the crank. Tighten the body snugly, then turn the extractor bolt clockwise to remove the crank. Once it engages, the crank will usually come off in two or three revolutions.
Park CCP-44 for Splined Cranks
- The Park CCP-44 is designed for use with Shimano cranks that do not have a self-extracting mechanism. In use, it is similar to the square crank extractor. Remove the center bolt and thread the tool into the arm. Tighten it snugly, then turn the handle clockwise to remove the crank. It normally takes two or three turns before the arm will come loose.
Park CWP-7 Universal Puller for Square and Splined Cranks
- The Park CWP-7 universal puller does not have an integral handle like the CCP-22 and the CCP-44. In use, it will require a large wrench to insert the tool and extract the crank. This all-in-one tool may be a good alternative for the home mechanic needing a crank extractor for occasional use.
Park Repair Help
- Park offers educational information on their website. The tutorials are detailed, highly informative and include some videos. This is an excellent introduction to bicycle mechanics for the beginner and an equally good information resource for experienced mechanics.
