A seal assembly is provided that extends along an axial centerline. The seal assembly includes a seal support, a seal housing, a plurality of torque pins and a plurality of stopper collars. The seal housing includes a plurality of slots arranged circumferentially around the centerline. The slots extend axially through the seal housing, and one or more of the slots has a lateral slot width. The torque pins are connected to the seal support. Each of the torque pins respectively extends axially through a uniquely associated one of the slots to a distal pin end. Each of the stopper collars is uniquely associated with and connected to a respective one of the torque pins at the pin end. One or more of the stopper collars has a lateral collar width that is less than the slot width.

1. A seal assembly for a turbine engine, the seal assembly extending along an axial centerline and comprising: an annular seal support;an annular seal housing including a plurality of slots arranged circumferentially around the centerline, wherein the slots extend axially through the seal housing, and a first of the slots has a lateral slot width;a plurality of torque pins connected to the seal support, each respectively extending axially through a uniquely associated one of the plurality of slots to a distal pin end;a plurality of stopper collars, each uniquely associated with and connected to a respective one of the plurality of torque pins at the distal pin end, wherein a first of the stopper collars has a lateral collar width that is less than the lateral slot width;a guide sleeve that laterally engages a side of the first of the slots, wherein a first of the torque pins extends axially through the guide sleeve, and wherein the guide sleeve has a lateral sleeve width that is less than the lateral collar width; andwherein one or more of the stopper collars are adapted to axially engage the seal housing during a first mode, and respectively pass axially through the slots during a second mode. 2. The seal assembly of claim 1, wherein each of the slots has a respective lateral slot width, and each of the stopper collars has a respective lateral collar width that is less than the respective lateral slot width. 3. The seal assembly of claim 1, wherein the first of the collars extends laterally between opposing collar sides;a bore extends axially into the first of the collars, and is substantially centered between the collar sides; anda first of the torque pins is mated with the bore. 4. The seal assembly of claim 1, wherein the first of the collars has a substantially rectangular cross-sectional geometry. 5. The seal assembly of claim 1, wherein the first of the collars has a substantially arcuate cross-sectional geometry. 6. The seal assembly of claim 1, further comprising an annular seal element connected to the seal housing. 7. The seal assembly of claim 6, further comprising an annular second seal element that axially engages the seal element to form a seal therebetween, wherein the second seal element rotates about the centerline relative to the seal element. 8. The seal assembly of claim 7, wherein the seal element comprises a face seal, and the second seal element comprises a face seal land. 9. The seal assembly of claim 1, further comprising a plurality of springs that are arranged circumferentially around the centerline, and extend axially between the seal support and the seal housing. 10. A seal assembly for arranging between a stator and a rotor, the assembly extending along an axial centerline and comprising: a stator seal support;a stator seal housing including a plurality of slots arranged circumferentially around the centerline, wherein the slots extend axially through the seal housing, and a first of the slots has a lateral width;a plurality of torque pins connected to the seal support, each respectively extending axially through a uniquely associated one of the plurality of slots to a distal pin end;a plurality of stopper collars, each uniquely associated with and connected to a respective one of the plurality of torque pins at the distal pin end, wherein a first of the stopper collars has a lateral width that is less than the slot lateral width of the first of the slots;a guide sleeve that laterally engages a side of the first of the slots, wherein a first of the torque pins extends axially through the guide sleeve, and wherein a portion of the first of the stopper collars projects laterally out from the guide sleeve; anda stator seal element connected to the seal housing,wherein one or more of the stopper collars are adapted to axially engage the seal housing during a first mode, and respectively pass axially through the slots during a second mode. 11. The seal assembly of claim 10, further comprising a rotor seal element that axially engages the stator seal element. 12. The seal assembly of claim 11, wherein the stator seal element comprises a face seal, and the rotor seal element comprises a face seal land. 13. The seal assembly of claim 10, wherein the first of the collars extends laterally between opposing collar sides;a bore extends axially into the first of the collars, and is substantially centered between the collar sides; anda first of the torque pins is mated with the bore. 14. The seal assembly of claim 10, wherein the first of the collars has a substantially rectangular cross-sectional geometry. 15. The seal assembly of claim 10, wherein the first of the collars has a substantially arcuate cross-sectional geometry. 16. The seal assembly of claim 10, further comprising a plurality of springs that are arranged circumferentially around the centerline and axially between the seal support and the seal housing, wherein the springs bias the stator seal element against the rotor seal element. 17. The seal assembly of claim 10, wherein the portion of the first of the stopper collars is adapted to laterally overlap and axially engage a portion of the stator seal housing.
