My 79 300SD had that type of pump I think? It was different from the pump on my '83 300D. Jabba was able to get me a rebuild kit at the time, that was at least 5 years ago though.

Re: [MBZ] Vacuum leak no booster no shut off.
I replaced a booster on the TD and that seemed to help a lot with vacuum. There were still some leaks somewhere that bled down the vac but while it was running it was OK. It's kinda a PITA job with lots of contortions to get the nuts off the booster up above the break petal but other than that not too bad. --FT On 5/10/19 12:17 PM, Curley McLain via Mercedes wrote: absolutely.

Re: [MBZ] Vacuum leak no booster no shut off.
If the vac pump had gone bad, you would have shut off, brake booster problem, and tranny shift problem. I've had this before on a 617. It sounds like you also may have moved the little linkage pieces on the shut off valve on top of the IP as well as knocked off the vac line. Those vac lines are a PITA, especially compared to the 300SD where the lines are not in the way. I'm always extremely careful when I change the oil filter on my 83 300D because of the tight vac line clearance. Hope this helps. Roger Roger Hale Dinnerware Classics, Inc.

If you have no vacuum at the booster, then take off the big line at the vac pump, and see if you have vac there.

Re: [MBZ] Vacuum leak no booster no shut off.
I did some research and it seems that the 80-85 cars utilize a piston type pump with piston rings and internal check valves instead of a rubber diaphragm and rebuild kits are no longer readily available for these newer pumps. I did see a kit or two on eBay but not sure I trust them. The entire pump is available as an OEM rebuild though from fcpeuro, autohausaz etc for a pretty penny.

I moved them away in order to replace the filter as I usually do, started the car and it wouldn’t shut off. I managed to locate and re-connect the disrupted vacuum line and all was well. Later on in the day, I noticed that I lost the boost to my power brakes and that the car would not shut off again. I searched but could not find any more disconnected vacuum lines! Any thoughts here? I’m starting to get very frustrated!

Re: [MBZ] Vacuum Leak Under Dash
The black tube is not connected to anything under the dash, so maybe it's the atmospheric vent. Green tube will not sustain any vacuum. Found some printouts from Marshalls time which state that I'll probably have to pull the dash and replace a vacuum unit of which there are five. I'll replace all five since pulling the dash was not much fun the first time I did it. Thanks John, Jim, Gerry - From: "Jim Cathey" I'd need to check, but it could be an atmospheric vent... Green is HVAC. -- Jim - From: "John Reames" I'd need to check, but it could be an atmospheric vent... John W Reames - The green tube with a white stripe which comes out of the firewall into the engine compartment in my '83 300D will not hold vacuum on the Mityvac. I'm guessing it goes to the climate control units under the dash. Can the climate control vacuum units be checked without removing the dash?

Re: [MBZ] Vacuum leak
Gerry asks: 2. Do you have to remove the ignition switch in order to replace the vacuum switch that shuts off the fuel to the injector pump. No, I think you can work through the instrument cluster hole to do this. -- Jim __ Ah, thanks Jim. After looking under the dash, that sounds better.

[MBZ] Vacuum leak
Hi Reid, (also my grandson's name) When a diesel will not shut down there's usually 2 possibilities - the vacuum line from the ign switch to the rear of the injection pump where it attaches to the vacuum shutoff actuator and the vacuum shutoff valve itself., If you have a vacuum leak in the passenger area - door locks for instance, - it usually doesn;t affect the engine shutdown. While the vac shutoff actuator is not very expensive (<$30) it can be tricky to install. It has a arm on it that must engage a lever inside the injection pump. If the arm is not properly engaged the engine will run a top speed until it destroys itself. The ignition switch can also be at fault, but more often the vacuum line will break where it attaches to the ign switch. If you end up replacing any vacuum hose, make sure you buy hose rated for vacuum service otherwise the hose will collapse when a vacuum is applied. To check the vacuum actuator - with the engine running, remove the vacuum hose leaving it attached to the rear of the injection pump - suck on the hose and the engine should shutdown. If it doesn't, the actuator is bad, if it does the problem is elsewhere -- Hope this helps --- - Good luck - Larry T (66 MGB, 74 911, 91 300D) www.youroil.net for Oil Analysis and Weber Parts Test Results http://members.rennlist.com/oil PORSCHE POSTERS! youroil.net 800-583-8601 Weber Carb Info http://members.rennlist.com/webercarbs ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
