Hi guys, I need to remove my front sprocket, but for the life of me can not get the nut off the output shaft. I have tried a wrench with a long (>3') pipe on it. I have tried heating the nut with a torch. And I have tried combining both. I don't have an impact wrench, and the nut is a square nut, so I don't have a socket that would fit it anyway. Does anyone have any advice about how to get this thing off?
