I have long threatened to convert my '89 RRC to a Bosch alternator, and this weekend the Lucas alternator broke again (third time in two years, but a month past the 12 month warranty this time). I'm converting using the advice on http://rangerovers.net/rrupgrades/electrical/boschalternator.html. I picked up the alternator this morning on the way to work, and it looks like a good one. I scrounged the two-wire connector off my parts Saab. I have my fasteners ready.
I'm stuck with getting the pulley off the Bosch unit. Has anyone here made the conversion? If so, how did you get your ribbed pulley off? I can't see how to get enough purchase on that slick pulley to stop it turning when I put my breaker bar on the nut.
I got it off, and easily too. I used my bench vise. This is my "new" vise that I've only had for <ahem> ten years. It has a rotating head with pipe grippers underneath. I'd never used them before, and forgot all about them, until I saw them quietly waiting under there, minding their own business. I gripped the OEM pulley with those pipe grippers and the nut came right off. Too easy.
