Engine drive chain sprocket

[Dream two]

Cleaning engine (on bench) inside right cover I noticed that my sprocket was kinda loose.
It was held on by a lock washer fastened with 2 bolts into the sprocket.
I undid these bolts and removed the sprocket, there appears to be nothing that can tighten up sprocket. Now I can't line up lock washer and replace sprocket, Anyone??
Thank you in advance.

1.Slip the sprocket on shaft.
2. Slip the lock on the shaft until it is in line with the groove.
3. THEN turn the lock into the groove to line up the hole in the lock to the sprocket.
4. Install bolts.

Figured it out in the meantime. So the lockwasher stops it from sliding of the splines. Now it is still loose. Can slide side ways a bit. This is to make sure the sprocket always lines up with the rear sprocket? If that's the case than this is the first time I've seen that. Cool.
