I took this video today while checking out someones 300cd (I just finished working on his 116 sd).


Poor guy, bought it in san fran. The PO told him he replaced all the filters and such. We were going over the car after this clip was shot he asked what about air filter, do i need one? We opened it up and it was GONE. No air filter. Poor guy drove the car from San Fransisco without an air filter, didnt even know it.


The vacuum pump is shot on the car. I told him I can rebuild it for him if he orders the kit. What kit is it, I know theres a later style pump and early style, one is a diaphram pump one is a piston pump. I know my 84 has a piston style pump. His looks a little diffrerent, is it the diaphram pump?


what does he need to order? http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=2CT05TC9L2CT05TJJA&year=1978&make=MB&model=300-CD-001&category=D&part=Vacuum+Pump+Repair+Kit&appEngines=_any
I see the check valves and the diaphram.




I came to the conclusion because his pump gives about 3 inches or mercury, with all orifices blocked and with the brake booster dc'ed and blocked off with a finger. I inspected the vacuum line and it is fine. Someone who has done this before needs to help me out, I told him id email him with the info on what to order. Thanks guys (and girls)
