Lucile, good advice above. I have found that if its stubborn do like Denny says, just keep stepping up the bit size until its out. Youc can get roll pins at the local auto parts or even a good Ace Hardware store. Drill it out and put in one a little bigger.
I know I'm getting ahead of the plan here but when you start on the brass bushings I usually see it they will come out easy and if not I stick a hacksaw blade through the hole and cut the little bushing into then peel it out.
When you put the new ones in set them in the Freezer overnight and then the new ones will press in with thumb or palm pressure. If you try to drive them in you will most likely ruin them.
ALSO, most of the bronze/brass bushings come a bit oversize to make up for any possible wear on the shaft itself. So, odds are you will likely have to ream them out. That in itself can be tedious. I took mine to my nephew to hone out on his honing machine but he was to aggressive pushing it on the honing stones and it actualy spun in the pedal arm.....lessoned learned! Hope yours goes OK.
