The only time I have had any trouble with this is in poor corn and the feederchain was too slack. Once the chain was tensioned properly I have not had this occur again. I recently changed the sprockets on the top shaft with loewen sprockets and these have timing marks that are suppose to be in alignment when installed. I don't know if factory sprockets have these marks or whether the three sprockets are always in time. The only other thing I could think of is that the top shaft is twisted.
