Lucas,
I'm assuming it is the coupling on the engine side of the driveshaft? If so, then, nope, no biggie.
If you have a screen cover, remove it. Then ensure that the coupling opening and the driveshaft hole are aligned. Tap in the spirol pin far enough so that it sticks out a little bit on each side of the coupling. Replace the screen cover.
If you have a long (about 12") punch, the task of finding your hammer may take you longer than tapping the pin in!
Good Luck!

P.S.
Oops! --- I just hit me you've got a 122 NOT a 123! So,,,, there may be more to it with a gear drive -- I just don't have one to know the difference..... Sorry.
