What part do you need?  There are just a few wires for electricity and then all the speaker wires.
Also what radio do you have?

They sell some harnesses also.

You will need a 27mm socket. I would recommend a deep socket and a short extension.

I would add some light weight oil via the plug holes and let it sit for a while before trying to crank it. You would need to do a fluids before starting anyhow.

For starters you need to remove all the plugs so you're not fighting compression.  You need a long wrench as well.  Turn clockwise facing the engine.  There is a large nut on the crank pulley for which you need correct socket and extensions as the nut sits pretty deep.

Mechanicals / How to manually crank engine

Last post by sbetts - 13 April 2024, 05:16 PM

Hello,

I have a 1974 450SEL than has not been driven in over 20 years. I want to see if the engine will move, but have never cranked an engine with a wrench. How do I? It looks like there is a plastic white cover over the crankshaft end, but before I pry it away I figured I'd check with you all to make sure that is the correct place to do this, and to hear other suggestions. What size socket would I need?

The picture clearly shows an 6.9 Engine.
The screenshot is directly from the 6.9 section in the service manual it is also the only engine where this is mentioned.
I would translate the text but it only says that this switch disconnects the vacum advance above 90 C engine temperature , sadly i was not able to find a part number for this exact switch only 1 with 63 C but without the vent hole.

Maybe because in australia there was no legal way to drive > 110 constantly ?

The photo depicts a V8 with K jetronic..so that limits the scope.
The arrows point to the distributor  port that ordinarily connects to the vacuum valve on the firewall to increase the advance when the a/con is switched on.

I cannot see what the other arrow is indicating. I cannot read German so it's a bit hard !
but the gizmo /temp control sender seems unique.I've not come across this before.

Why they need to do this seems crazy coz if ever a car was going to run hot at hi speed it would have to be Australia and they are not fitted to 6.9's at least !
The article you are referencing appears to be a full service manual extract..ie .it is not a "bulletin amendment?"

Let's see what else presents!
