It won't matter if it is used straight on. The sprocket gets pressure from the chain pulling so me using an impact driver dead straight to the sprocket won't damage anything as the force is sideways just like the pressure of the chain, as impact drivers rotate just like the chain does... The force of the impact driver is used to rotate the impact driver, it won't damage the output shaft because it doesn't put pressure against the output shaft.
If it's broken, it's not fixed.
