Just be careful whacking the pedal arm pins. They tend to mushroom the threads. Heat and give a little tap on the non threaded end to break it loose. Not too hard o that end or you can get it more stuck. Also give the pedal a little wiggle before hitting it on the thread side. Hit a couple, another wiggle, hit again, another wiggle. Repeat until it comes out. Worst case it isnt budging. You smash the bolt out but mushroomed the tip. Just get a new pin to replace it. Double check measurements as there are a few sizes of these.
