	The design of 5-cell elliptical 650 MHz β=0.9 cavities to accelerate H⁻ beam of 1 mA average current in the range 467-3000 MeV for the Project X Linac is currently under development at Fermilab. A new design of the Helium Vessel (HV) was developed for these cavities with the main goal of optimizing the frequency sensitivity df/dP by keeping the cavity stiffness reasonably small. We also present a design of the new lever tuner system. The HV in the new design is equipped with the tuner located at the end of the cavity instead of the initially proposed blade tuner located in the middle. We will present mechanical design results and ANSYS analyses for both the slow and fast tuners.
