chainslap,

I have not had the need to do this to a 350SD/SDL so I am not certain about this. But on a 220D or a 240D the pin is pressed in from the front of the engine, and it has a threaded hole. I used a stack of washers with the hole bigger than the pin, and a nut on a bolt that threaded into the tapped hole. It worked fine (no room for a "slap hammer" or other impact type puller). Hope this helps, Jim
