Sean,you need to flip disc over.The raised side goes toward pressure plate.You can use driveshaft to align disc and then tighten bolts.Those springs can be hooked and then pull bearing up over fork.Then slide driveshaft thru bearing and into coupling on trans.If coupling stayed on shaft,pull it off and put on trans because it won't go thru bearing.Sometimes the bearing will try to slip off forks when you are putting tractor back together,so keep an eye on it until shaft starts into pressure plate.Good Luck and take care.These tractors may be small,but they can still hurt you.
