As always takes longer than you hoped. I tried a repair using the plastic weld abut it would not take. Even got a washer made at work and tried to use an epoxy whilst in a vice. This did not work as the cog would not grip the rod. I could have glued this to the rod but decided to source a new cog
I ordered a new cog from a bloke in Germany pretty sure he gets them from America.

Part arrived and I fitted it the other week. Finally got it into the car on Monday night.
Note the blob of epoxy to make sure it stays on.
and working :-)
