A gas turbine engine turbine section comprising: an inner diameter structure; a turbine exhaust case surrounding the inner diameter structure and having an outer ring and an inner ring in concentric and radially spaced relationship and a plurality of circumferentially spaced hollow struts interconnecting and supporting said inner ring and said outer ring to each other; an outer casing surrounding said outer ring ; and a plurality of tie rod assemblies (120; 300; 400) interconnecting said inner diameter structure and said outer casing , each of said tie rod assemblies (120; 300; 400) comprising: a tie rod having: an inner diameter end ; an outer diameter end ; and an eyelet of an outer diameter spherical bearing formed at the outer diameter end ; at least a first clevis (172; 320; 420) carrying a spherical ball between arms of said clevis (172; 320; 420), said spherical ball captured by the outer diameter spherical bearing eyelet , a shank (193; 322; 422A, 422B) of said clevis (172; 320; 420) extending to an outer diameter (OD) end of said clevis (172; 320; 420); and a tensioning bolt mated to a threaded opening formed in said outer diameter end of said clevis (172; 320; 420) whereby tightening said bolt applies a tension to said tie rod relative to the outer casing , characterised in that : a radial span (L 2 ) between a center of the outer diameter spherical bearing and an inner diameter surface of the outer casing is at least 50% greater than a radial span (L 3 ) between an outer diameter (OD) surface of the outer ring and the center of the spherical bearing. an inner diameter structure; a turbine exhaust case surrounding the inner diameter structure and having an outer ring and an inner ring in concentric and radially spaced relationship and a plurality of circumferentially spaced hollow struts interconnecting and supporting said inner ring and said outer ring to each other; an outer casing surrounding said outer ring ; and a plurality of tie rod assemblies (120; 300; 400) interconnecting said inner diameter structure and said outer casing , each of said tie rod assemblies (120; 300; 400) comprising: a tie rod having: an inner diameter end ; an outer diameter end ; and an eyelet of an outer diameter spherical bearing formed at the outer diameter end ; at least a first clevis (172; 320; 420) carrying a spherical ball between arms of said clevis (172; 320; 420), said spherical ball captured by the outer diameter spherical bearing eyelet , a shank (193; 322; 422A, 422B) of said clevis (172; 320; 420) extending to an outer diameter (OD) end of said clevis (172; 320; 420); and a tensioning bolt mated to a threaded opening formed in said outer diameter end of said clevis (172; 320; 420) whereby tightening said bolt applies a tension to said tie rod relative to the outer casing , a tie rod having: an inner diameter end ; an outer diameter end ; and an eyelet of an outer diameter spherical bearing formed at the outer diameter end ; an inner diameter end ; an outer diameter end ; and an eyelet of an outer diameter spherical bearing formed at the outer diameter end ; at least a first clevis (172; 320; 420) carrying a spherical ball between arms of said clevis (172; 320; 420), said spherical ball captured by the outer diameter spherical bearing eyelet , a shank (193; 322; 422A, 422B) of said clevis (172; 320; 420) extending to an outer diameter (OD) end of said clevis (172; 320; 420); and a tensioning bolt mated to a threaded opening formed in said outer diameter end of said clevis (172; 320; 420) whereby tightening said bolt applies a tension to said tie rod relative to the outer casing , characterised in that : a radial span (L 2 ) between a center of the outer diameter spherical bearing and an inner diameter surface of the outer casing is at least 50% greater than a radial span (L 3 ) between an outer diameter (OD) surface of the outer ring and the center of the spherical bearing. <EOS>
