The front sprocket has a splined washer that goes on the outside of the sprocket. The splines on the washer don't line up with the splines on the sprocket, so when everything is tight, the sprocket actually has some free play towards and from the tranny, because the splined washer ends up riding in a groove in the sprocket shaft. Is this normal? I can't see any other way it's supposed to be, but don't remember it being like that last time I had the sprocket off (long time ago). Thanks.
