FSM + EPC data => Chassis / model / transmission / drive train information
 

G'day Folks,

Occasionally - well quite frequently - there's a thread where someone is asking if a transmission out of one model will fit in another.

Sometimes there's a thread where someone wants to change from automatic to manual

Sometimes someone is looking for a different differential...

I've asked these questions myself!

Here's the data I've collected so far. I hope it helps.


Please note:-

I have obtained this data from a copy of the FSM in original language(!), and the Russian EPC data at EverythingBenz - Mercedes-Benz Forum and Web Search Using Google, and a tiny bit of my knowledge.

So the data here is what was meant to be fitted to each model. It isn't necessarily saying that an alternative won't fit.

There could be mistakes in the data - use it at your own risk.

I recommend that if you are using the data to buy a replacement part you should put the two parts side by side before parting with your hard earned cash.

To the best of my knowledge the 5 speed manual gear boxes are of a different length than the 4 speed manual gear boxes and they are also of a different length than the automatic transmissions. This means you need different propshaft sections - and perhaps the differential won't be of a good gearing too...

Also bear in mind this is a work in progress

If you have any data that you wish to add to it please say and I'll post up a copy of the spreadsheet.

Oh yeah - I forgot to say.

There's no w114 data in there yet

There's hardly any W124 data, but I've got most of the 107, 115, 123, 126 data => honed towards AUTOMATIC transmissions - 722.1 / 2 / 3 and a bit of 722.4

How to find the numbers on the parts
 

It has just occurred to me that perhaps not everyone knows how to find the part numbers on the parts.

First things first. The chassis number or VIN. For model identifiaction purposes you need to find the Mercedes VIN - I understand that in the US there is sometimes a US VIN. This is of no use to you if you want to extract information from the PDF file I've posted above.

An example of the "good" chassis number / VIN is

WDB 123 130 blah blah blah (where blah blah blah will be more numbers)

From the PDF in the first post you can see that the 123 130 blah blah blah chassis numbers are for

(W123) 300D

BUT you can also see in the same file that there are several other 300D variations out there. So sometimes someone might be selling something from a "300D" but it won't necessarily have been fitted as a standard part on ALL 300Ds...

...this is partly the reason why I've compiled this information.

To find the chassis number on a W123 you can find it in the following places. Please note these places are sometimes different if you've got a true Euro model (not just the headlights!) or a US model.

On US models sometimes you'll see it on the windscreen on the left hand side

On all models you should be able to find a chassis number stamped into the bulkhead / firewall in the engine bay.

Engine numbers tend to be on the BLOCK stamped on the left hand side of the engine - here left hand side is taken as though you are sitting in the car looking forwards.

Transmission numbers - should be on the right hand side of the transmission (again sitting in the car looking forwards) just above the oil pan.

Note about differentials - you are unlikely to find a part number stamped on the casting(s) that compares favourably with the part numbers in the PDF. You're more likely to find a number for the casting. However you can more easily find the final drive ratio by scraping a bit on the back of the differential as shown in the picture below.

Future plans
 

I'm going to extend the information to include suspension springs - they seem to be a popular swap item.

Are there any "wants" out there? In other words (apart from filling in the blanks!) is there any other information that would be useful?

HELP ME OUT!
 

If anyone has data that needs to be included in the file please post it up here.

anyone have data for trannys in the 90's?

Thanks Army! I'll go check my numbers now.;)

Wow, that's quite a compilation you have got going there. Nice job!

Would be nice if there was more 124 data - I need to do a tranny swap on my 1992 300D 602.962 722.418 and I'm trying to find other cars that have the same tranny.

I've found lots of information on EverythingBenz - Mercedes-Benz Forum and Web Search Using Google

There you'll find a stripped down racing snake version of EPC which should point you in the right direction - let me know if you need some help.

Thanks Army,

I looked at that site - nice EPC!

Is there some easy way to find all the cars that have a 722.418?

I'm guessing that only a 722.418 will fit, not a 722.4XX

Using the EPC via that link the answer is no. It isn't that good...

...I'm not even sure if the grown up EPC (www.startekinfo.com) is any better for that type of cross referencing.

I got lots of information via the W123 German version of the FSM where there are chapters on the CD for the transmissions. That is where I have seen that kind of cross referencing before...

OK, I found an interchange site: Mercedes Benz 722.6 transmission application guide

722.418 124-270-08-00 1990 -1993 300D-2.5 TURBO
722.418 124-270-08-01 1992 -1993 300D 201-0502
722.418 124-270-47-00 1991 300D 2.5 Turbo
722.418 124-270-81-00 1993 300D 2.5

But this just brings up another question, i.e. will any of these 722.418 fit my 1992 300D? Sheesh....

It is good to know what casing will fit - thanks for the input.

For automatic transmissions though you might find that certain transmissions shift at different points for different road speeds. For a correct shifting automatic transmission - meaning one that performs as specified in the FSM - you need to make sure that the governor and the differential are matched at the very least. In certain cases the valve bodies are also not the same across all types.

I realise that the speed at which "it" shifts isn't always what people are worried about - but I think it is worthwhile mentioning it just in case.

You mean the 722.414?
722.414 201-270-19-01 1986-1989 190D 2.5 123-0202
