Your crankset isn't a press fit if it is a Force, at least according to the Sram install sheet. I just changed out my 2013 Sram Apex for a 2013 Sram Force crankset, the Apex used the press fit the Force doesn't. The Apex comes off by loosening the 10mm hex on the drive side, the chain rings/crank arm come off along with a plastic (approx. 1/2") spacer, the NDS arm and shaft then pull out. On the NDS there is a tension adjuster. The Force installs from the dive side, opposite of the Apex, the Force uses shims and a wave washer to set the tension on the NDS.
