do u have to drill out the old one or does it tap out?
Depends on which pin. The roll pin (spring pin) is hollow and can be drifted out. The sensing pin is solid, some are drilled thru and can be drifted, others are in a blind hole. The blind hole pin usually has enough to grab with vise grips and can be gripped and pried up. If it is flush, you have a major problem. Centering and drilling it out has to be done with a lot of caution on a machine to prevent damaging the hole. You may want to just replace the torsion spring retainer and springs as they weaken with time. Most likely why the pin broke. Normally I've seen them bent from spring weakness.
