Are you using the correct outer washer and nut ?  We have seen a number of failures from using the wrong outer washer and nut which may interfere with the chain and sprocket.. I would suggest putting it together and taking a hard look at it to ensure that it is running clean, free of interference… rotate it by hand and I think you will see the problem. We have run 11t drivers with great success.
