Okay let me be clear, it was the (my) "estimated" distance to the right of "D" range (when facing the engine) and the 2-3x was just the measure I used to describe that a little movement seen on the indicator may translate to be more when measured on the opposite side (pulley). I did not mean it to be the actual calculation. Exhibit A was the FB photo I saw that had no belt at all. Again, from my previous post up to this point, I was just stating my opinion that a small change on the indicator isn't necessarily equal to the movement at the pulley. The photos I posted a few days ago suggest that as the temp goes higher or running the engine longer, either the belt is shrinking or the pulley tightening up. Either way doesn't make sense to me.
Hah okay just wanted to make sure.
As for what happens to the belt as temperatures increases most materials will deform/stretch, the tensioner would be calibrated to operate at a variety
of ranges so it is likely applying more tension to the pulley as engine speeds/temps rise to prevent the belt from slipping.
My $0.02 on the matter at least, I'm sure Avedis will correct/elaborate on anything I missed/got wrong.
