Park Tool CCP-44 Spline Crank Puller The CCP-44 Crank Puller by Park Tools is specifically designed to remove crank arms from splined Shimano(R) Octalink and ISIS Drive(R) bottom bracket spindles that do not use a "One Key Release" system. It uses a long, comfortable handle and a fine thread for the leverage needed to remove tight crank arms. Now with a stronger rotating tip system to ensure smooth operation and long life. Note: The CCP-4 will not work on crank arms that fit standard square, tapered bottom bracket spindles. NOTE: The CCP-44 is used on cranks using crank bolts larger then 8mm. ISIS Drive and Shimano Octalink may use either 12mm or 15mm bolt thread. "Power Spline" cranks use an 8mm bolt and use the CCP-22 for removal. features Related Articles: CRANK REMOVAL AND INSTALLATION: THREE PIECE CHAIN TENSION FOR TANDEM FRONT ENDManufacturer's Part No: CCP-44UPC: 763477001276 | Park Tool | Ccp-44 Spline Crank Puller Park Ccp-44 Spline Crank Puller
