Good day, I think you might have a torque problem, or your pulley is not thick enough for the pulley nut to firmly clamp down on the pulley. Most of the time I see this, it is improper torque of the pully nut. And double check the thickness of your pulley to make sure that the nut is providing good clamping force. We make a lot of alternators with out woodruff keys all together, just need to be torqued correctly. If you are in the UK, we have a tech service rep there, his name is Neil Jepson and you can get him at njepson@prestolite.com Thanks
