1972 220D w/240D engine - SVO conversion

The instructions that come with the STC 100 kit are written for and photographed when installing kits in 116, 123 and early 126 300SD diesels. The kit can be installed in other models but you will have to deal with some “issues” and modify the instructions to fit your application. The specific “issues” for each chassis are listed below:

115 CHASSIS SEDANS 1968 to 1976: This is one of the more challenging diesels to convert primarily due to the location of the battery. It takes up the ideal space where you could mount the SVO components near the injection pump. Even if you mount the filter in the trunk there is still hardly enough room to mount the BMFM on the left side of the engine. The best solution is to move the battery to the trunk. That will require running a very heavy battery cable back up to the starter inside/under the vehicle. Even with the battery in the trunk you will need to modify the brackets of the BMFM and may need to remove the filter from the plate and mount it alongside. No instructions are available specifically for the 110 and 115 chassis and you will need to do some drilling and fabrication on your own . Please remember the picture manuals are for the 123/126 diesels and will require interpolation on your part. Basic fuel routing and hookup is of course the same. If you do not want to move the battery you can mount the components on the right side of the engine but this will require a long fuel hose run to the injection pump with the potential for cooling off of the oil during migration. You could offset this some some by insulation your fuel hoses. You will be on your own when dealing with these remote mount issues. For this type of conversion above average mechanical skills are a MUST.
