Not sure what car you have, but it's a little more complicated than that. Also, for the 350sdl, you have to set it to 15ATDC. -- remember that it will hit that spot on two different rotations. I WOULD STRONGLY RECOMMEND THAT YOU DON'T DO THIS UNTIL YOU BUY AN A-B TEST LIGHT!

I've got a 350sdl and removed several of them. By the way, for a little more than $1000, you can get a new one (parts of it may be remanufactured) and I bet you will spend about that to have yours redone. Anyway, that's the route I went. Comes from Germany so you have to be patient if you do that.

You have to take the front of the engine apart including the vacuum pump. (get a new gasket). Then you remove the cruise control actuator which is behind the pump and will keep you from pulling it back.

After that you need to remove the fuel lines. The one between the IP and block is a bugger - I just remove the hose from the fuel filter and then remove the other end when the IP is loose. (get new sealing washers for the hose ends). The diesel fuel will leak out, so plug them up.

You have to remove two hoses from the IP and one from the fuel pump. Then the individual

Then the electrical connectors. One on top of the IP (has a locking device that you have to turn before it will release). Then the electrical plug at the rear of the pump.

You have to insert a small metal basket into the vacuum pump opening to keep the chain in place. When this is in, you can remove the three bolts holding the IP in place. There is also a center bolt that you have to remove -- THIS IS A LEFT HAND THREAD.

After these are off, there are two bolts on the rear of the pump to the block.

Then the pump can be pulled back and out.

To put back in, you should get the pump locking device and lock it in place, put it back in - THEN REMOVE THE LOCKING DEVICE BEFORE TURNING THE ENGINE!!!!!!

Once the IP is back in, use the A-B light to get it right. Even if you used the locking device, it still won't be right and you need the A-B light to get the timing. Once you get the timing, you put everything back together and make sure you fill up the fuel filter with fuel and have your batter charged and it will start after a few long tries.

There is a little more to it, but that's pretty much the basics
