Hi BB,

The clutch sprocket is the top one mate. wink
It is past its used-by date and IMO is unserviceable. wink

The lower ones are the cutter sprockets (2 in one, primary to secondary) are serviceable; the secondary drive sprocket is also serviceable.....I can take comfort that you will only have to purchase a new top sprocket and all should be well, if regular maintenance is carried out, chains replaced as necessary and regularly greased with a good quality grease. wink
cheers
