Ducati Cam Pullet Tool for Pantah and other two (2) valve belt drives, as well as four (4) valve 916 belt drives. May fit other models, please check our bike! These tools allow you to hold the camshaft timing pulley from rotating, and the socket tool to loosen the cam pulley retaining ring nut, as well as retightening with a 1/2 inch drive wrench. This set replaces factory tools 88713.0138 (Pulley Holder), 88713.0139 (T-Bar Nut Tool), and 88700.5644 (Holder and Nut Socket Tool). The holding tool will fit pulleys with the holes on the part for the tool, not the earlier models that have two protrusions for a tool with notches cut out. Not for late belt drives with the three socket head screws in the face of the pulley and no holes to fit this tool. Tools come with black oxide finish preventing corrosion to assure many years of service. This tool is not made in China or Hong Kong. It is professionally made in the USA on the state of the art CNC equipment with 100% quality inspection.
