Before I had a press and a bearing splitter, I used to remove the snap ring and use a block of wood on the garage floor to protect the splined are of the tailshaft and let the main shaft assembly drop on to the wood a few times. The weight of the first gear and synchro assembly would pop the bearing off quite easily. Be sure to use heavy leather gloves or you WILL pinch your skin when the bearing does let go! No me gusta...
