Abstract: A disk gang assembly constructed in such fashion as to eliminate the long center tie bolt. An arrangement is provided comprising a plurality of like disks spaced axially apart on a common axis and held in spaced apart relation by a plurality of interspaced spacers. Each spacer is provided at opposite ends with radial flanges to receive and sandwich disks respectively therebetween. The disks and flanges have notching bolt holes through which sets of bolts or the like are passed to secure the disks and spacers together as a rigid axial unit. The spacers are mutually axially piloted on each other and opposite ends to maintain the coaxial status and each pilot includes an annular shoulder for receiving a complementary central circular opening in each disk. End spools are also provided for carrying bearings for mounting the assembly in a supporting frame.
