Guys- removed rhs engine cover and there's a large (14mm) bolt in front of the water pump seal. I've tried to remove it (carefully with a piece of alu bar between the cogs on the water pump gear and the clutch cogs. Assume this is an anti clockwise thread and I just have to give it a bit more muscle?

Cheers for any comments

Found the seal? Next question is.......what's the best way to remove this seal without damaging the RHS cover (looks like pushing from behind is best) and where's the best place to buy these? Another question is can you recommend supplier of clutch holding tool for the Yam SY 250 engine? Thanks for all your top tips to date! Greg
