1023-70 Cam bushing line reamer tool

Achieving perfect alignment between the cam cover bushing and the inner cam bearing is critical for engine longevity. This JIMS cam bushing line reamer is designed to ream the bushing to the exact size required, working through the inner cam bearing to ensure a perfectly straight path. This process requires the cases to be disassembled for proper access. It fits 1970 to 1999 Big Twin models, excluding Twin Cam engines. For the most accurate results, this tool should be used in conjunction with the JIMS cam bushing and bearing alignment test tool, part number 978293, to verify your work before final assembly.
