As you have seen my bad luck & clumsiness in the regulator swap case - rather an easy job badly done I'm to admit, do you think I would be sane & wise to try dismantling the whole lot when I'm told by some skillful big boys that it's rather fiddly?!The replacement alt looks like new! Seems a waste not to fit those new bearings to the old one. Especially if you have no immediate need for it. Have you tried to get them off?
