James,

Do you have the crankshaft out of the top housing(point side)?

The top crank side should be 20mm shaft and if so the top bearing will be correct.

As to getting out the top bearing you need the crankshaft out then you get a drift to drive the bearing towards the centre as you will see in this drawing.
