3rd method. Freeze bearing and after cleaning and deburing the swing arm bearing socket heat the bearing socket with a torch. Use a wide flame and heat through and through. Not too hot but heat soaked through not just the metals surface. Take clean, cold soaked bearing and slip into the arm with fingers no tools involved. This has worked for me every time so far. The combo of heat and freeze is enough to get the bearing well smaller that the clean de-burred bearing socket.

When I rebuild electric motors for work I use freeze/fry method to install bearings. Almost all manufactures make the interference difference between the bearing and the shaft or socket to the bearing makers recommended requirements. This is a small enough delta that freeze/fry will more than equal the difference. To make it tighter will deform the bearing outer or inner race.
Dead clean and de-burred is very important. I clean and then hit the shaft or socket with 400 grit cloth to be sure there are no little bumps or crud that will hang up the install. Have the puller ready in case of a stuck bearing but if you prepare well they slide right in or on every time.
