The timing tools in the pictures go into a Plug that you remove from the side of the Governor Housing.

On my 84 I used the one in the left picture. (Note: The timing is done 15 degrees After Top Dead Center.)

You most likely need the one in the right hand picture.

It would be best if you could post a pic of your Fuel Injection Pump so I could see what type of Plug you have on the side of your Governor Housing.

To the OP, there is a bit in the FSM that SOME pumps are offset by 3 teeth due to a problem from the bosch factory.

The FSM? Is the FSM you are referencing applicable to a '79 240D?

I have not read instructions on how to use it but I bet it is the same 15 degrees ATDC after the Compression stroke just like the later models. That is the same timing degrees that the RIV,AB light references to.

If he happend to have one of the IPs that needed the 3 tooth offset it would still flow time at the normal range of degrees.

That does not mean one should not use it. Good call.

While using the Timing Pin does not compensate for wear inside of the Fuel Injection Pump it does compensate for Timing Chain/Gear stretch/wear.

I am glad to hear that....since that IS the specified way to set it in the FSM... LOL

I wonder if Whunter has or would do a video on it.. ? Or anyone else that wanted to... ?

The guy who rebuilt my engine put something together wrong, so that even though everything is actually working correctly, the marks will never line up properly for the purpose of timing the engine.

"It turns out that a number of IPs made in 1982 were mismarked, so that you actually have to set the driven element so that the wide mark is 3 splines PAST the timing mark. If you've done this, the pump works like any other. This information is clearly set forth in the OM617 engine manual, proving yet again that, even if you know how to do a job, RTFM first."
