Trying to remove the rusty needle bearings from my rg arm but they won’t budge I’m using a sliding hammer as hard as I dare the arm is flimsy and really light and I don’t want to damage it any tips?

I tried a slide hammer with my rgv bearings without any joy
Had to use a puller in the end

When I replaced the bearings on my f2 swing arm I had the same problem I got round it by hack sawing gently through bearing casing two cuts did it, came out with no problem after

It’s stepped there is a gap off about 10mm behind the bearings to get a puller in ,i might be able to grind them out

One method of removal would be to remove the bearing internals so that you only have the outside bearing case still stuck in the arm. If you spot weld on the inside of the bearing case it will cause the case to deform and shrink making it easier to remove.

Heat and lots of it. Heat will break the rusted in seal. Let it cool down. If the slide hammer puller doesn't budge it then try a bit more heat. If it still doesn't move support the thing on some wooden blocks and drive it out from the far side. A normal hammer is no use you need a proper lump hammer.

We always remove the inner bits, then run a mig welder around the inside of the outer case. This will shrink the case for easy removal.
Usually works on all bearings.
