Hi NaderIts quite difficult to do yourself actually. There is a steel sleeve in the top of the bell that is press fit in. That is what the one way holds on to on the outside and the pinion on the inside of it.
You'll have to get this sleeve out, then drill and tap the bell walls for set screws and put flat spots on the sleeve for the setscrews to hold on to. When you press the sleeve back it in needs to line up with the holes you made for the setscrews.
Its a little bit of a job, you may be better off to have MA do it for you. Sorry I don't really have pictures of it handy, but all you see is two setscrews on the side of the bell about centered with the one way after the job is done.
Hope this helps.
