Is there an upgrade to this please? Norge

Evening all,
More questions re my 2014 Norge GT 8v and apologies if it upsets anyone. :slight_smile:

I have taken the timing cover off to get it cerakoted as it is currently in a terrible state, on removing it I noticed it has a plastic drive wheel for the oil pump, is there an upgrade to a metal one for this please? My old Centauro has had its one changed but not sure if this is the same?
Also when I refit the cover with new gasket, is any sealant like hylomar required? The manual doesn’t state if it should or shouldn’t be used.
Thank you for any help.

Not totally sure but I think mine (1200 Sport) may be metal - need to find more pictures.
