You're going to need a good pair of snap ring plyers. The bearings will can off with a bearing puller. Don't polish to make installation easier. The bearings are not difficult to install. You're going to have to make a dummy shaft to re-install to countershaft. Buy the small parts kit so you can replace all the bearings and snap rings. The snap ring that holds the input shaft bearing on is not included. That bearing part number is D8UZ-7064-A and can be found on e-bay. It's a unique bearing because of its thickness and it doesn't come in the small parts kit. Good luck, If you need the repair manual to help you, I can send you a *.pdf file to help you.
