Abstract: An assembly includes a case structure, a seal interfacing with the case structure, a first pin, and a main pin hole on one of the seal and the case structure. The first pin extends through the main pin hole and is fixed relative to the other of the seal and the case structure. The assembly also includes a second pin and a secondary pin hole on one of the seal and the case structure. The second pin extends through the secondary pin hole. A cross-sectional gap area between the second pin and the secondary pin hole is greater than a cross-sectional gap area between the first pin and the main pin hole. Also included is a bolt hole on one of the seal and the case structure. The bolt hole is circumferentially located between the main pin hole and the secondary pin hole.
