Our Inner Cam Bearing tool kit is a shop grade tool set that both removes & installs inner cam bearings easily, quickly, and accurately in 07-later H-D Twin Cam engines (also incl 06 Dyna). It features a heavy duty, tool steel plate which attaches directly to the engine cases with 4 thumb screws. The collet is used to extract bearings from the case, and the driver is utilized to install the inner cam bearings perfectly straight and to the proper depth. Replacing inner cam bearings on your H-D engine has never been easier.
