No problem. Not just secure, but adjusted so the belt is riding in a dead horizontal position vis a vis the pulley and the platter. If the pulley is sitting either high or low on the shaft depending on exactly how the suspsension is set up (ie. a little higher or lower), my thought is that the tension induced in that situation by the pulley either on the high or low side of the belt, might be contributing to that "belt shedding".
What I do in setup is place an average record on the platter with clamp, loosen the tension on the set/securing screw on the pulley, then manually rotate the platter a bit. This will move the pulley and essentially self adjust it into the proper position on the shaft so the belt is dead horizontal when playing and the pulley can then be tightened down and secured in the right position.
