Thanks for your trouble with this, it all sounds a bit dangerous. I've done quite a few belts on other cars without problems. I can see the dangers of the belt being in the wrong position on any of the sprockets but if the new belt went back on in the exact position as the old one, ie if the the number of teeth between runs was the same as the original, then would that be ok or does something go out of adjustment just by virtue of taking off the old belt??? Thanks Ray
