I take it you wont have a small puller to hand ?

So the easiest way is to get your newspaper off the coffee table and shred it in to small pieces then soak it in a bowl of water then insert the wet paper in to the hole in the end of the crank shaft so its full then with a drift and hammer compress it whilst you keep adding more wet paper eventually this will push the bearing out ! .

Hope that does the job .
