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.

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.
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?
Full set of vacuum lines and fittings that run from the top of the valve cover to the VCV valve on top of the injection pump. Included hard-to-find good multi-pin plug and pins for the 3/2 valves.
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.
