Simple to replace, here are some helpful pics, tips and torques. Depend on where you look and what year you have, this might help confuse you. I just torqued mine at 80 ft/lbs.

Front drive gear nut(36mm)

Torque specifications per Haynes manual- gearbox sprocket nut 72-87 ft/lbs. (pg.17)

Thanks again to 5T for the sealant tip on the sprocket and locking washer, to try and avoid additional leaks.
Keep away from the case flange, when using the bench mounted repair of chocking the chain.
