I'm not 100% sure but i believe the 2014 models, besides having different motor mounts, fixed the binding issue by removing the unnecsary 3rd bearing that holds the motor shaft coupler in place. By not having the 3rd bearing it avoids any binding from slight misalignment in the assembly. If you are still using a 2013 model, it may help to remove this bearing by pushing it out of the housing, removing the clip holding it in place with the shaft coupler, and seperating it from the shaft coupler. Then reasamble without the bearing. It may help with binding issues.
