This owner put off replacing the vacuum pump FOUR years.
The timing chain is intact but damaged, and must be replaced. There are more pictures here. 1992 300D vacuum pump failure pictures by whunter - Photobucket . |

Makes me all the more reassured that my preventative replacement on my 601 was worthwhile. Old pump looked fine, but I don't like the looks of the exposed bearings. Just an accident waiting to happen.

In the second picture, if that's the vacuum pump under the radiator hose, it looks like it has screws holding down the cover. It might be one of those oddball mid-series pumps with an open bearing but screws holding down the cover. There was a listing of such a beast on eBay a few years ago. For the cost of a gasket and an hour's work, check to be sure!

Well according to service records it sounded like my 300D had vacuum issues for about 50,000 miles before I got it.
I pulled my vacuum pump to replace my injection pump and realized my open bearings were a little lonely. Opened up my oil drain plug, got a big magnet drug it around the bottom of the oil pan and... I put in an updated pump around 180,000 miles, but I think the old pump fell apart around 130-140k.

What was the date code on the failed pump? (See photo below for secret decoder ring). Also, as Sixto mentioned, did the pump have the Torx screws on the front?
