Yeah thanks for that but i've got it all timed up mint just need the tensioner to play abll then she'll be running.

Inicdently i've got the bottom cover off as i knocked the little plate off the bottom of the tensioner arm which sits on top of the plunger so had to take the bottom cover off to try and fish it out, luckily i could see it and i got it out with some long nosed pliars.

But, it'll be easier to refit the bottom cover if i remove the bottom pulley [as i've just undone all the 10mm's and swang the cover around] got any tips how i can remove it? i've got the bolt out but the pulley is siezed on, tried hitting it/levering it but it's not having it and my three legged puller is too big.

I'm thinking just using silcone around the edges and slide the cover round, do it up and hope for the best.
