Abstract
The sole support for the rear disk rim side plate of the 1st turbine stage is the seal extending between the 1st and 2nd stage turbines. The fir tree broach on the side plate fits into the broached rim of the turbine disk which is extended axially to radially restrain each side plate. This configuration eliminates the heretofore used bolts and nuts or rivets.
