300SD part id and how remove
 

I am attempting to r an r the shut off diaphram. There is an electrical attatchment right next to the shut of diaphram (toward the front and I need to remove it so I can get at the inside 10mm bolt and remove and replace the new diaphram. Seems as if that would have to be removed before unscrewing the ALDA.

New Subject: Where should the alda be set, I unscrewed the adjustment by accident and would rather set it now than sneak under there to adjust it with the manifold on...
1993 300SD....thanks

I've replaced the shutoff diaphram in my SD. I don't recall anything being in the way at all.

Woops, you have a 603; different IP.

Michael, note that it's a 93 300SD.
