OK, next dumb question. Could all the other belts I have bought been put on running in either direction? The reason I ask is because some older belts, maybe 10 years old, have been coming apart at the seam. I just figured it is because the adhesive has failed due to age. I have run them with the seam angled in the direction of rotation and opposite the direction of rotation and it has not made a differernce. These belts are a good quality from a company we all know.
