Cam sprocket plate

[Fogdevil]

Have picked up on some posts that people have or have not got a thin metal plate between cam sprocket and the knock bolts.
My knock bolts were not flanged so I wonder if it was a way to spread the loading from the knock bolt to the cam sprocket. [ Guests cannot view attachments ]

I don't have the plate on mine,  haven't even seen one before.   I always threadlock those bolts in place.  All hell would break loose if one came undone.

I have the plate on mine. Maybe it's a mod on later models, mine being a late 1978.

Threadlocked mine too Mike.
Julie,mine is a very early '77 f2.
My sprocket is solid(as in the shop manual) but I have seen 'holed' sprockets(as in parts list)??
