Do you know the 0231402008 distributor ?

Hi Norbert,

Great info. I will log on the bosch archive site.

Hi Volker,

you are right there is only a single vaccum hose connected for retard.
May be the distributor have been refurbished or modified sometime in the car history.
I will go with the 0 231 402 001 settings.

The bosch archive is very detailed.

dust protection cover
Primary cable 880 mm long with coaxial connector
shutdown speed 6650 min

Hi Sylvain,

you have to be careful when appending attachments from 3rd parties. Copyright laws forbid that unfortunately and some lawyers make a stupid business out of it.

OK
thank you for removing it.

this is not Mercedes-Benz but Bosch knowledge. The 0 231 402 008 has same rpm curve as 0 231 402 001. But it has a double vacuum with retard and advance. So you have 2 connectors from throttle body to ignition distributor. That is surprising as the old M116.981 for sure had a throttle body with just retard connection. If I am correct, advance connection on your ignition distributor should not be connected. In all other items it behaves like 0 231 402 001 distributor.

Hi Volker,

You were right the second vacuum connection is not used and not plugged.
There is a rubber to close it.

Hi Volker,

sorry that i have to bring this topic back to life & because it starts in english i will continue in the same language ...

I have exactly the same 0231402008 distributor in my ´72 350 SLC. The current ( original ) throttle hody has just one connection for retard advance. I am wondering now if it makes sense to change the throttle body to the later one with the 2 connections in both ( retard & advance ) ways.

What you suggest me & what will be the result / effect ? Is it worth the effort ?

THX !!!
