I remember a discussion on another forum years ago relating to bearing roller size, and the steps of measuring the shaft & housing , and using machinist's handbook to calculate the o/s bearing size... I am not a machinist,
but I do have a nos scout drive shaft (.875) and the housing which according to sources was 1.375 I.D. new.
Based on that, what is the theoretical maximum I.D. allowable on the drive housing before oversize rollers are no longer an option?
