A long time fan favorite, if you are replacing the timing cover bushing on your 36-69 Big Twin with a new bushing, then it needs to be reamed.

This tool will do the job, and leave the correct diametrical clearance and finish in the process.

These are made by hand, for you, in Milwaukee. 

Works on either needle bearing or bushed cases.
