Hi Blsd 49,
Many thanks for your help, I have tried Joblot auto and unfortunatley they are out of stockof these gears, they were very helpfull but say that these original parts are very rare and they dont manage to get hold of them nery often.
My pump has the ten gear option and it looks like I will have to get one machined over here and as it has ther distributer drive inside its going to no doubt be very expensive.
Regards
Bob
