My Ender 3 had a broken part so I replaced all the plastic above the extruder motor.

After learning how to safely take off the pressure-fitted hobbed gear, I installed a new one that could be replaced more easily. Now the teeth of the gear are too low to reach the PLA. The rest looks fine, I've tried flipping it upside down (the squeezy handle won't fit) and I've tried moving it as high up as I can. Do I have to buy a new motor with a longer rod? (sorry I don't know the names of these things)

As previously mentioned, the gear has already been replaced. It's not stuck and I now have one with screws (its the one in the picture)

So, as mentioned, you could get a new stepper motor. As an alernative, have you tried flipping the hobbed gear around (as shown in this picture)?

The question Problems with stock gear with no screw on Ender 3 pro, more specifically this answer and this answer describe that after changing the gear, the shaft is too short. It is advised to just buy a replacement stepper or tap the shaft from the bottom of the stepper to extend the shaft. First option is probably the easiest solution.
