Bearing info provided here
The plain spherical bearing for the lower rear-shock bearing for a Pampera 2-stroke (125/250/280) is a GE12C/K4; mine is a KML brand.
The inserts levered out ok, after which the bearing removal/insertion was mostly BAU.
The only thing you can't do with a spherical bearing (unlike a std 2D round bearing) is to use the old one to drive in the new one. This is because the inner bearing (drilled-through sphere) would impact with the same on the new bearing, so you don't want to bash on that and damage the bearing surface.
The bearing is PTFE coated and 'self-lubricating'.
I used a hex socket (18mm) to drive out and squeeze back in (using a vice) the bearing as this was the biggest socket that fitted into the tube in the bottom of the shock, and gave good contact with the outer bearing surface.
Hopefully the reassembly will be uneventful and I'll be rolling again v soon, without the 'slop' in the rear end.
The movement in the bearing was only a few mm, but the effect of leverage means that the back end of the bike moved a couple of inches.
Ride safe and good luck spannering.
