Analysis found that visually, the press ring was moving freely along the shaft.The press ring is not likely to completely detach from the assembly due to the handle at one end, and the shaft radius and balloon at the other.The balloon assembly should be installed until it stops at the handle, it was 0.147¿ away from the handle which is out of specification.The balloon assembly stopped just distal to the high point on the probe shaft.The probe shaft diameter at this high point shall be 0.1660¿ / +-0.0005¿.The minimal wall thickness of the balloon material shall be 0.0090¿ per side which may be reduced after being assembled onto the shaft diameter.The measurement over the balloon material and high point of the shaft was 0.177¿ which is where the press ring should be seated.The press ring inside diameter shall be 0.180¿ / +-0.001¿; the press ring was forced over the balloon and removed to measure the inside diameter; the ring slid freely along a 0.1813¿ pin which indicates an out of specification condition.If information is provided in the future, a supplemental report will be issued.
