I never had my old SMC 135/2.5 lens apart but I know that in many other Pentax lenses if the rear end is re-assembled incorrectly it can prevent the aperture from working. Does the aperture actuator lever pivot ( so that it doesn't maintain a 90 degree angle to the rear mounting flange) or does it remain rigid and just rotate around the mount?
