folks,here is a way that you can get those stuck pins out: mapp gas and bee's wax! you can get mapp gas at home depot and bee's wax at craft store's in candle form.for some reason bee's wax has a "wicking" effect.i use it on frozen pinion drives that are in the food processing machines i service. found out about it when i was working for a major engine rebuilder back in the 80's. at the time we were tearing down 140 motors a day and the guys pulling out crankshafts used it for frozen main cap and rod bolts.check it out. good luck
