Mine is exactly like the diagram. What I mean is, it seems that the direction of force on the pulley (created by the belt tension) would be an
average of the belts approach angle and departure angle. In diagram one (on the left) - that average is nearly vertical. In the diagram on the right, the averaged angle of force is closer to a 45 degree angle, sloping down as it goes from left to right. Does this conjecture make sense?
In talking with one of the mechanical engineers I work with, he said that he wouldn't be too concerned about the changes - they are negligible HE said some results could be negative, and some positive - less stress on the belt, because of one less switchback being a positve. Also, less cumulative stretch is possible with a shorter belt...and the tensioner spring may actually work MORE effectively when it is more directly in line with the force it is fighting. He did bring up a couple points - one - make sure that the tensioner still has some travel left in it and is providing adequate pull. Two is that the tensioner spring may change force if it is more or less compressed than intended. The second concern doesn't seem to be an issue, as the tensioner appears to be almost in the same place as with the old belt...
anyway...
