Swing arm needle bearing removal?

I went allt the way back to the archives in my quest to find a method for this. But to no avail. So how do you remove the needle bearings in the swing arm of a 3CL? It’s puzzling (in the league of putting a model sail ship into a glas bottle). A 17 mm socket fits inside and can bee used force the bearing out unevenly or a hacksaw blade to cut a longitudal gap may be another option? But I hope there’s a better way….?

God fortsättning!

I read that thread, are they still belting them out, using the cut down washers? I've done many (but not Laverda) with a bit of penetrating oil, some heat and the cut washers, sockets, etc, but use all-thread. Good for pressing back in too as shown on my old Norton/Matchless. I may be completely off base and missed something, it happens on occasion (err, daily).

Hello. Regarding the disassembly of needle bearings in the Swingarm, I weld a bushing in the bearings, and then you can take a dorm and knock it out, very easy
 
I 'enjoyed' removing the bearings from my RGA Sprint's swinging arm. Trying to use proprietary pullers, heat, drifts resulted in a lot of frustration, but no movement. In the end I stripped the bearing internals out, and then ran a bead of weld around the inside of the bearing race to shrink the races and along with a lot of lubrication, made it easy to drift them out.
