Yes. It also requires you to "stab" the distributor into the engine with the rotor at the correct position so that as it seats itself the rotor ends up in the right position. It meshes with another spiral-cut gear as it is pushed in, so the rotor turns when it is either taken out or put back in. If you were to take the old one out, it would be important to note where the rotor is exactly, both in the seated distributor position and just as the gears disengage when withdrawing it. Sharpie markers can help.

It also helps to have the engine at top dead center in case you screw that first part up. Then you have to sort of play around with it so that the rotor is pointing to where the #1 cylinder's spark plug wire connects to the distributor cap. Don't ask how I know that...
