Are they the spline drive cranks with the SD sprocket combo? If so, only way to get it off is a rubber mallet and lots of hitting. I really hoped you used enough grease and the correct way to install SD sprockets.

You should really use tons of grease for SD honestly.

Possible I suppose, but you might have just got it seized on there. It's always a good idea to grease anywhere that metal comes in contact with metal. Can't really say yes or no without actually seeing it though
