Änderungen nach Baujahr und Sonderausstattung

[bilboo]

Hallo Allerseits, vor kurzem habe ich mir eine 2 Türer Limo von 37 in unrestaurierten original Zustand gekauft. Meiner Meinung nach wurden lediglich die Rückleuchten und hässlichen Blinker nachgerüstet. Er verfügt über ein Kofferset und ein Rollo für die Heckscheibe. In diesem Zusammenhang interessiert es mich, was es alles für Sonderausstattungen gab.

Leider finde ich keine Liste über ab Werk bestellbare Sonderausstattung.

Sowie welches Jahr was geändert wurde.
Ich fände es schön wenn wir hier sowas zusammen tragen könnten. z.B. HBZ rund/eckig , ab wann Eierleuchten, wann innen-/außenliegende Winker, Kennzeichen Beleuchtung, lackierte Radkappe Serie?, Reserverad Abdeckung Serie? Kühlerverschluss, Wasserpumpe…..

Lg Chris

-Motor mit Stehbolzen/Schrauben
-Getriebe unsynchronisiert/teilsynchron

Hallo Chris, ich bin zwar keiner Kenner der Vorkriegsmodelle, aber ich glaube du findest Antwort auf die meisten deiner Fragen in den Ersatzteillisten. Hier ist auch ein Link mit diverse Information: https://www.inverso.pt/mercedes170V/
Viel Erfolg in den Studien!

Hello Chris, You ask an excellent question. A question of much detail and study and discussion of the parts books from the period. First you must think of the cars not from year to year ( which is not totally incorect) but between RB numbers. The RB numbers are the block of numbers in which a car was produce and align roughly with a calender year. I believe the production year before the war was April to April of perhaps September to Sepetember. I will be corrected here! The parts books are aligned in Editions A- H (Ausgabe ) that start in 1936 the transition into the war years where things get abit funny so to speak with military modfications and limted production. A entire different topic. Im y case i have a 1937 vehicle . But the parts book edition B and C touch calender year 1937. Here again withe RB number of you car you can zero in on the exact configuration of your car by carefully reading the part numbers of the items you have described. But if the car is in a transition period do not bet your last penny as likely parts were used up before transitioning to the later version. Now the next question. Where was the car delivered. Different countries had different rules for lighting and bumper requirements. This has to be considered. Also there were numerious after marked additions that could be applied to a vehicle. Some of these can be found in part supplier catalogs from the period. Just my thoughts from an American guy who has studied this topic a bit. There are guys on the forum that have forgotten more about these cars than I will ever know. This is an excellent knowledge base. other factors. Do not forget the impact the war had on the maintence of orginal car configuration. Parts wee applied as spares to keep the cars running on the road. The 50 years after the war, if a car was in Eastern Europe there again every effort was made to keep the car running. This could include three pistons of one size and the fourth of another. There is also a record of the parts and the correct replacement parts according to Merceds Benz. A simple example; The old style master cylinder, is correctly replaced by the new style master cylinder. It is a correct replacement for the pre war cars. Engines if a 170V engine was replaced by Mercedes Benz in 1955 you would get a more modern engine than a true 1937 engine and it would be a correct replacement.

One more item of thought. The beautiful black and white Works pictures from the pre war period. Be careful in what you see. Some of these pictures are of proto type cars and may be slightly different than a standard production car. This is a fine point but in some cases quite different in the details.

First answer The radiator star changed Between Ausgabe C and D. That would be before RB 10136017. AusgabeC shows the sharp star and Ausgabe D shows the round or more traditional star. Another important change here is the intake and exhaust manifold. I will work my way down your list as time permits. Others may have additional thoughts. jim

Two more I show the four spoke steering wheel all the way through Ausgabe G which is 1942. Then I show the three spoke steering whell which started in post war period Ersatzteilliste 136.I or Ausgabe H. I would suspect that cars assembled in the immediate post war period could have had either four spoke or three spoke steering wheels until production lines were established for the three spoke steering wheels. A quick study of Lug vehicles you will see four spoke wheels in some of the pictures. Fuel tanks. In Ausgabe C you will see two fuel tanks. a 43-liter tank, part number 13681f, and a 34-liter fuel tank. Part number 13681g. One can only assume in this period you had a choice of fuel tanks. This could be proven by looking at build sheets from the period. They may list fuel tank size. Then for the Roadster and Cabriolet A there were different fuel tanks due to the shape of the body. I do not have an Ausgabe B parts book, but the Ausgabe A parts book only list the 34 liter tank, and the roadster/cabriolet A tank. Time to go to bed. More to follow. There are others that may dispute my findings and certainly can add greater details. Jim

I will continue down the list with the cylinder head studs DIN 939 . It is my belief that the engine studes continued through the war period. With the introduction of Edition H parts book (post war) you will find a switch to six sided headed bolts with a 136 part number as opposed to a DIN number. Whis is interesting. What triggered this change I do not know. My thoughts are that iit is more cost effective to produce a single bolt as opposed to a stud and a bolt. There were also changes in the post was engine block castings that could have sparked the change to bolts. For sure cylinder head bolts are not listed in the pre war parts books.

Brake system master cylinders. Parts book edition G shows the flat cylinder. Edition H shows the the vertical master cylinder. So this change took place in the post war period. However the vertical master cylinder is the correct factory replacement master cylinder for the older flat style.

Chris you should find a copy of the Ubersichtsblatter fur PKW- Ersatzteile Typ 170. This document has the different parts and their evolution of change for the 170 family of vehicles. it is quite interesting if you are really interested in the details of change. Also the different editions of the parts book (ETL) you can find the changes there. I have not addressed lighting configurations as there were changes from year to year, but primarly the changes where associated with the country of sale of the vehicles. Then there SA Sonder- Ausfuhrungen configurations. Bumpers changed a bit from country of sale as well. I believe the books i listed can be found in reproduction form for a reasonal price. Original editions are difficult to find and quite expensive. I will leve this topic, and hope that others will add their knowledge as i am just one person who is not a native German speaker and i do not write in German so perhaps not the best source, however my information provided comes from the documents I listed. I also have a 1937 Reuter parts catalog which shows SA parts for the 170 vehicles. Jim
