Perhaps a silly question, but do you have the correct steel ring holding the sprocket in place, with the three slot-headed, stepped shank bolts holding it in place ? The sprocket is not intended to compress the cush rubbers in a static position, and it must be able to rotate slightly in both directions, with the movement being controlled by the three vanes on the back of the sprocket engaging between the three pairs of cush rubbers, and limited by the extent of the three arcuate slots in the sprocket face.
