Default longer timing belt for ZVH

Does anybody happen to know if anybody supplies a slightly longer timing belt (with an extra tooth or two) for a ZVH engine?

I have a slight problem whereby the timing belt is exceptionally tight even at its loosest setting. I'm sure I remember that once you were able to get a timing belt with more teeth.

Many thanks

Mine was always fine on a cvh belt, did you use the smaller tensioner from the 1.3?

Yes indeed I have.

This is a black-top zetec bottom end. I didn't drill and tap the holes for the tensioner myself, but it seems that because of the block, one of tensioner holes has to be in a location that makes it quite tight before you even tension it.

My previous bottom end (silver top) was fairly tight, but okay

Can the tensioner be modified to five some more slack?

Hello,

Here is a picture of my spare tensioner and the other one fitted on the engine.

Looking at it now, I don't think it is too tight, as you can twist it 90 degrees. But it would be better if there was a bit more adjustment. As you can see, it is about as loose at it can go.
