Hi Steve,
When I rebuilt my Bosch generator, I used an impact wrench to remove the
bolt that holds the pully on. If memory serves, I may have lightly
clamped the pulled in a vice (it's pretty stout, anyway). I believe it
has the normal right handed threads.
When switching from Marelli to Bosch, I think that you should only need
to change the Generator and the Regulator. I would think that the
starter (and the remaining electrical components) would operate
regardless of the charging system.
If you are at all interested in converting to an alternator, this is the
perfect time. Greg Field (as well as others) did a very nice conversion
on his Eldo. I took some pictures of it at the National rally this year.
Check them out at this URL. I haven't made the switch myself yet, but it
is something I want to do in the future.

| hope everyone had a good christmas. mine went well except for the "little problem" I had with my generator (see posting "bosch gen. parts"). I was hoping to get the engine in and started up over Christmas weekend. I got it in, but after I broke the pulley on the front of the gen. Friday, it put a crimp in my plans and increased my beer consumption over the holiday drastically. Spent a lot of hours on the internet looking up info on Bosch generators that could have gone into much more satisfying wrenching. I'm hoping someone out there will take pity on me and answer a few questions as I try to sort this out. 1) Does anyone have a Bosch Generator they want to sell, or know where to buy one? Working or not. (Bosch generator # 0 101 302 091) . I broke the cast front pulley by knocking the Gen off the workbench onto the concrete floor. Even just the pulley would be nice (pulley is MG part # 1270 0125, Bosch part # 1106602026). 2) I never took a Gen apart before and I'm having a problem figuring out how to remove the nut that holds the pulley on. How do you keep the shaft from turning when you apply torque to the nut? Is it possible this nut could be reverse thread before I spend a lot of time unwittingly tightening it? 3) I have a Marelli Gen on my ambassador and also a spare one that PO said was "good as far as I know". How much of a pain/expense would it be to switch over to the Marelli? Any comments on whether or not that's a good idea? 4) What about alternator conversions? Anyone have any experience with these and pro's and con's of doing them? I'm sure you all know the feeling, after a couple of months of work and prep the thing's about to go together and the bonehead mechanic just broke a vital and seemingly irreplaceable part. Oh well at least the store isn't about to run out of beer. off to work now. Steve |
