Cam Wheel Lock Tool - $40
Cam wheel lock tool holds intake cam wheel in place during cam belt installation. Essential tool for cam belt replacement/valve adjustment operations on all 4-valve Ducatis. Select the proper tool for your application. I recommend purchasing the cam wheel rotation/holder for rotating the intake cam. It can be done by hand, but it is very difficult. NOTE: The tool only locks the intake cam in place. The exhaust cam needs to be able to rotate slightly when installing the belts. The tool is only necessary on the vertical (rear) cylinder.
