6.9 distributors (again)
« on: 13 July 2020, 04:36 AM »
So, I’ve found the ignition distributor fitted is 0 237 405 002 which I understand is for the M117 in a 450SL.

My car is an Australian spec 6.9, and you would think it should have the USA version distributor as the engine is the same low compression version, just without cats.

I am curious though, would it be at all possible if someone with an Aussie delivered 6.9 could confirm if the correct distributor should be 0 237 404 007/ 004 or if it is in fact meant to be 0 237 405 002.

Any assistance would be greatly appreciated.

Cheers,
Tim

Tim, I looked in the service manual, and it specifically mentions the 0237405002 number for Aus delivered cars, same as US models.  Euro is 0237404007/004

Thanks Daniel, at least I can say I have the right one then.

Sounds like it’s back to troubleshooting.  8)

Thanks Ptashek,

I’ll probably go down the path of a new unit, but first I’ll check the advance at 3000rpm and see where it’s at.

And yet, despite all this, my USA donor car had the -004 euro version as well as the green Euro wire.  Certainly it could have been an incorrect replacement at some point.  Still, it's odd, as this car was a dealer-bought USA model, not a gray market import.  It lived its whole life in Utah and was always serviced by the local dealer.  It's a wild shot in the dark, but I wonder if the different versions have different performance at altitude?  But it still doesn't make much sense.  That same car had a dealer installed high-altitude WUR per US emissions requirements with the original nicely boxed in the trunk.  If the dealer swapped in a Euro distributor why not save that along side the WUR?

What is the association with the green Euro wire you're referring to?  Every W116 that I've seen made after 1975 had a green wire going from the distributor to the ignition switch gear.

I got it from this board.  In various threads gone by the green wire has been referred to as the Euro distributor version.  I'd have to do a lot of searching to find the threads/references, but they're there.  Doesn't make a lot of sense on the face of it but I took it at face value.

My Euro Spec ordered and delivered new to Brazil (Data Card Dealer code 775) also has Distributor # 0237 405 002.  Many ROW (Rest of the World) markets outside Europe received Euro Spec cars with Low compression engines due to the quality of gasoline available.

Regarding the green wire; a while back when I inquired at a reputable shop, the owner asked, after checking his reference materials, if the lead was green or black lead. We checked and saw it was green and therefore he stated that my US spec 6.9 had the Euro dist. Relatedly, the lead on an extra engine I took from a wrecker had the black lead, not green. Chapter 2: Sometime later when I took the car to the local Benz dealer for a smog check, they advised me that there was a recall on my distributor. Concerned that I would lose the advanced timing of the Euro dist I did not proceed with the replacement.

Thank you!  There is confusion after all, so it looks like I'm not insane!   Seemed so odd that my USA parted car had euro dist.

Anyway, Does anybody have the advance curves for that respective versions?  Or maybe it's in the manuals....
