ABSTRACT:
A turbine disk assembly 20 has an extension including arms 34 and a groove 38. Nut 40 engages the groove and bears against the extension. A square head 48 on the nut fits a standard torque multiplying wrench and arms 34provide a reaction so that no adapter tool is required. Groove 38 permits pulling the disk assembly by use of the nut, and also allows sleeve 50 to hold the nut from loosening.
