Hi,

What method should I use to extract the guide rail pins when I do the head gasket job.

Are these pins threaded so a slide hammer can be attached or are they dowel type pins?

Thanks

Martin,

If they are anything like the pins in my 16V, they are a simple pressed fit, dowel pin type.

I clamped mine with a pair of vice grips and used a pry bar with a small piece of wood, working around the pin, to leverage them off.

They have threaded holes, MB makes a little extractor tool to pull them out. A slide hammer would work if you have the clearance, but usually you don't have the room. There is a small screw-in plug you need to remove to get to it.

Thanks,

There are several types of guide pin pullers that are listed for the
Mercedes.

Here is a picture of one type. Is this the one that is used on the M104 engines? Is the Pin Extractor 6mm?

There is also one type from Sir Tools with a small sliding hammer. Will that type work also.


Thanks

Looks more like this one, but it doesn't seem to apply to a 104 motor.

I don't know if a 104 pin is like a 103 pin. If it's similar, what I did was use a piece of metal that rested against the head on either side of the rail such that plain old bolt and washers used as an extractor tool did not put pressure on the plastic frame of the rail.

If this doesn't make sense to you then the 104 arrengement is probably different from a 103.
