Started the new bearing by placing the old one on top of it and going around with a standard 2lb claw hammer knocking it a little at a time. Finished using 1-1/16 socket and a 49oz dead blow rubber mallet. If I kept using the old bearing it might've gotten stuck in the pulley with the new one. Though the image shows the drive side of the socket being up, i flipped it for hammering, placing the drive side against the bearing. Seemed flatter/safer
