Is your diesel suffering from hard brakes, poor or no engine shut off, climate control problems, or even funky transmission shifting??
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.
FITS ALL 123 chassis cars from 1977 to 1985 and ALL 126 Chassis cars from 1981-1991, both Gasoline and Diesel models! If you are not sure of your application just pop your hood to see if you have one inline on the drivers side of the engine compartment.
Included are instructions for testing the valve as well as removing and replacing it yourself. The valve is located at the back of the fuel injection pump. If working properly it will shut the fuel off inside the pump.
Until now there has been no practical information for the DIYer to know how to test and replace their own vacuum 3/2 valve assemblies. There certainly been no inexpensive hose replacement kits. This new kit by Kent Bergsma solves both those problems.

This is a high quality aftermarket part. Genuine are no longer available. The main line is the same for all U.S. turbo diesels 1981 to 1985. There may be some variation on the small vacuum rubber hose attach points. Here is the arrangement of the vacuum attach points.

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.
Here is a great way to save some money repairing your old Mercedes vacuum door lock actuators. When they go bad it is almost always due to cracks in the rubber diaphragms. These can be easily replaced once you remove your door panels and remove the units.
These five page step-by-step illustrated instructions will walk you through the correct procedure of removing your old worn and cracked door lock rubber diaphragms from the actuator housing and replacing them with new ones. These are procedural instructions only.

This unique kit will allow you to hook up a 30 in HG vacuum gauge between your vacuum control shifting valve (VCV) and your transmission modulator to test the VCV for proper function and to tune it for peak shifting performance.
This is no longer available so we custom make this in our shop. This hard to find 5 way vacuum connector can be used to replace a worn or deteriorated factory connector you as an alternation you can use it to replace 2 - 3 way connectors where needed.
The VCV valve controls the critical shifting patterns of most diesel automatic transmissions from 1978 to 1985. This includes the 1978 to 1985 300SD, the 1980 to 1985 W123 300D, 300CD and 300TD and the 1980 to 1983 240D.
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.
