Yeah I'm pretty tired, apologies if that didn't make sense, with some dinner in me lets see if I can do better.
There are actually 2 differences in the new alt vs the old one. The shaft is longer and the mounting arms mount it farther back. The first is a problem because the pulley won't meet the key and the nut won't catch the pulley. The latter is obviously an issue because the pulley doesn't line up with the other pulleys. Fixing the latter issue halfway fixes the former so I took my spacers, one went under the alternator fan (which was too close on this alt anyway), the other just above the fan. That got the pulley pretty well situated, then I added some washers between the pulley and the nut which made up the other. Cranked it down with the impact gun (how did I ever get by without one?) and she's all good. -Curt Date: Fri, 28 Dec 2012 16:59:36 -0700 From: Craig <diese...@pisquared.net> To: mercedes@okiebenz.com Subject: Re: [MBZ] Wooo boy!

It's not entirely clear from your description that this modification puts the pulley on the new one the same distance from the alternator mounting bracket as it was on the old one. Is it?
