Some one tell me how to remove and replace the crankshaft bearings on a 31cc Ryobi?

I have a Dake ratcheting arbor press. Press the crank shaft out then the front bearing and seal I use a bar or a socket from the rear to press the front out. Bearings need to go in the same way. There is a small diameter difference and if you press both bearings in from the same direction you will have issues as the bore changes in the snout.
