Adding to Jims comments when drifting out from the inside of the crankcase you will see two (one either side of the crank) small half round indentations in the crankshaft. If you place your drift in these and onto the bearing inner race then alternate one to the other whilst knocking out it should come easily once heated around the bearing and carrier.
