I own a 78 300 SD w116... I have owned the car for 3 months and just about have it running the way I want it ... My problem,,While trying to shoot Freon ,, I moved the main vacuum pump line. to my horror ,a large peice of the vacuum pump broke off in my hand... Apparently the previous owner JB welded the vacuum pump together... Before this incident my car was running like a top...Now my car won't turn off, and my brakes are stiff.. I called around Houston, my home town and no one has a 3 line vacuum pump.. I have a back up motor , but it has a one line vacuum pump...
Several yards here in Houston have 2 line pumps.. Could I use one of these ,, Or should I try to clean and re-JB Weld the pump back together.... Any ideas as to where I can find a 3 line pump......
Sorry for being so long winded......Thank You ...... Juan

Juan,

Try Mercedesshop PartsShop on this website. If they don't have one, post it here again, and I think I might know where you can get a used one.

The early 617.95 engine vacuum pumps with two diaphragms are driven differently than the later ones. You have to use the type that came on the car or change the injection pump timer to the later type....and that is a real pain. Early pumps were driven by a splined coupler, later ones are driven by an eccentric on the face of the pump timer sprocket.

Regards,
Randy D.
