I went & saw what Digger had posted & I replied to Ralfguy, who I had failed to respond to.
I sure cant fault Serow's idea, put the tire in line & let the belt do what its gotta do. I have been working from the assumption that the wheels would be aligned IF the pulleys were & maybe thats just not so, IDK>
Anyway, here is my post from Technical, & I like that tool Digger has. It looks pretty handy for lining the thing up.
Dang Ralf, I never saw your reply, Im sorry. Let me see if I can make that more clear.
In the oil field, big pumps are belt driven, the belts, if cut & laid out straight, would be around 40 feet long, so the pulleys are very big & the distance from power point to the pump is quite a ways. In order to line the pump up with the drilling rig, we would use a string, held tight across the edge of the power point on the rig, that showed us where we had to get the edge of the pump's pulley, to line the belts up. They used 6 belts, ganged on these big pulleys. I used to toss old gloves in just to watch them get torn to shreds. So, a string, pulled tight, makes a straight line. By using the belt to pinch one end & roll the bike so the belt takes the string to the farthest point forward possible, then pulling the string back & across the rear pulley, all the way across it, not just back to it, then the edge of the rear pulley can be brought to alignment with the edge of the front.
Once the rear is adjusted to satisfy, marking the rear adjusters might be a great idea, because as Digger has pointed out, they arent marked exactly evenly.
