Lots of different techniques, here is mine. I assume they are tapered roller bearings. 1/ Pry the cage off, all the rollers will fall off too. 2/ gently grind a flat spot on the bearing ring with an angle grinder, you do not want to go too far and hit the steering stem. I always do this on the back side of the triple clamp so you can get good access with the grinder 3/ Hit with a cold chisel, with the blade aligned to the stem axis, and the ring will split 4/ lift it off, it will be quite easy 5/ keep the split bearing ring to use as a drift to fit the new bearing, just reverse it and it gives you a good surface and a snug fit with which to press or tap the new bearing in place cheers Blair
