Please could anyone tell me if this requires replacement? There is a clear lip on the inside circle.
The face shown is the bearing face and it’s from a 948.
Many thanks

If there is a lip I would recommend that you replace the plate.
For general information and regarding camshaft end float:-
The fore and aft movement of the camshaft should be 0.007".
The fore and aft movement of the camshaft can only be adjusted by machining the camshaft gear.
To increase the movement machine here:-
