you need a drift,something smaller than the pivot shaft you feed it through the opposite bearing then tap the other bearing out, aim to tap the internal part of the bearing a bit at a time 12 oclock 6 oclock 3 oclock 9 oclock
tip tap not bish bash a wooden dowel should do take youre time if you hit one side too much you might jam the bearing.One of mine had siezed on the shaft :roll: so grease the bearing seats (metal to metal contacts)when installing the new ones
