I did a search and found nothing, so dont blast me about that. I need a break down of the removal of the vacum pump on my 83 300D turbo. I want to rebuild it and want to make sure I do not drop anything into the engine, or mess with the timing chain. Anybody performed this procedure, any tricks or traps I need to know about?

Clean the front of the engine up, remove the vp, rebuild or replace as you see fit and bolt the new one on. Obviously you will have to remove some of the vbelts on the front of the engine to have room. Make sure you have a new gasket and the old gasket surface is clean.

There are two designs ( that I know of ) ... I have great pictures of TCane rebuilding the earlier type ( on my 1980 240d ).... They were designed to be used for the FAQs pages.... I just watched and took pictures ... so I can not provide the proper narrative..... but it was very straight forward ....

It was done in the car without removing the radiator...

Thanks for the pics, I have the piston type vacum pump. It cam off like engatwork discribed. What a difference proper vacum makes on a lot of the systems. Trans shfts better engine shyts off quicker, and the locks are faster. I also cleaned the boost control line and overboost valve, that helped a lot too. Again, thanks for the input as usual this forum works wonders.
