If you have an early 300SD and your vacuum pump fails, you could find yourself “up the creek without a paddle.” The actual mechanism of the pump is very robust and it hardly ever fails, but not so with the rubber diaphragms inside the pump.
FITS THE FOLLOWING: 115, 116, 123, and 126 chassis. Here is a diesel item I have put together that every Mercedes diesel owner should have.
Is your diesel suffering from hard brakes, poor or no engine shut off, climate control problems, or even funky transmission shifting??
Note: Works only on models that have two vacuum lines coming of the pump cover. I am seeing lots of vacuum pump problems with the older diesels. They are reaching that age regardless of mileage where the pumps are failing right and left.
FITS THE FOLLOWING: ALL 123 and 126 chassis 240D, 300D, 300TD, 300CD, and 300SD 1980 to 1985 with later style vacuum pump (only one line coming out of top). In 1980 Mercedes changed the design of their diesel vacuum pumps.
Fits late model 123 sedans ONLY from 1981 to 1985, such as the 300D. Be sure your gas door lock actuator matches this before ordering! This is a new plastic sealed unit as used on the later models.
If your diesel engine is starting to shut off very slowly or maybe not at all and you know your vacuum system is ok, it may be time to replace the vacuum fuel shutoff valve located at the rear of the injection pump.
When was the last time you knocked one of your vacuum lines off around the oil filter housing, only to discover when you tried to reattached it that the fittings or hose were swollen and would just not stay connected?
This vacuum line is white and is 4 mm in size. It is used on all 107 108 109 110 111 113 114 115 116 123 124 126 chassis. You can use it to replace any hard vacuum line on the engine.
Here is an easy DIY tip to repair a broken vacuum hose nipple on your main vacuum line running from the vacuum pump to the brake booster on the older diesel engines. $2TIP
Kent opened this up to make sure the diaphragm was in good condtion. Check valves appear to be almost new with no oil contamination, so we suspect this is a low time pump or had a kit installed when they were available.
1978 to 1985 Diesel VCV ( Vacuum Control Valve ) Internal Inspection and Service Instructions - On Demand Video
Kent delivers a very detailed 24 minute video on understanding how this valve works and how to fix it if possible. You will learn how to recognize a valve that is just too worn out to repair. No bleeder valve repair parts are available and there is not way to DIY fix one if it is badly damaged.
Maybe your non-turbo automatic shifts just a little too early or a little too late? Maybe your turbo diesel transmission jerks a little too much or flares during shifts?
Kent will explain the theory of operation in simple terms, why it is so important for proper transmission shifting performance, and how to test it hooked up to the engine's vacuum system with the engine running.
If your early door lock actuators do not have any cracks in the rubber diaphragms, but they just won't hold vacuum - it may be possible to fix them by taking them apart and cleaning and resealing the outer lip of each diaphragm.
These instructions will walk you through removing and reinstalling your pump from the engine, inspecting and opening the pump, mounting the pump, removing, inspecting and reinstalling the pump piston, installing new seals, check valves and cover plate.
