Radiator ROD Support

[John Nguyen]

Hi,

My 170s Cab-A did not have radiator Rods support, I'm thinking about fabricate this set in a fancy stainless steel and polish them shine as chrome???

Question:
- Are they both Identical pair.
- Are they 220/170 all same Sedan, Cab-A, Cab-B.

Do not use stainless steel. It should be better to manufacture it from common steel, polish it very good and than galvanize, it will look like chrome. Stainless steel have different electrical potential so if you do not protect aligning surface with paint or some insulating material you will get excessive corosion on contact surface.

They are actyally "handed" in the center portion as they pass over each other in the same horizontal plane and the end towards the firewall has the eye towards the top.

Thanks for posting the images. Now I have something to work from to build a set for my 220 Sedan.

In my opinion, mild steel is the way to go. But if stainless makes you happy, go for it. Remember that stainless is much harder than mild steel and the fabricating will take more care.

Another less costly option would to take your existing rod supports and powder coat them in chrome.  Not quite a chrome finish but comparable to a polished stainless look.  I don't know about elsewhere, but here in southern California powder coating is really inexpensive.

Sample in picture above is borrowed from a friend.
I have seen an earlier type and Newer type, this Newer type has a slot at mid section made of hollow tubing.
Following attachment is detail drawing Pete might like it, with the right tools it could be fun to build.

Thanks John! This will make the fabrication easier and as you put it, I can have some fun instead of frustration.

I'd like to hijack the thread and ask about the prewar radiator: what's the support like at the bottom? There is a vertical metal part riveted to the radiator bottom, with a big hole on it. Through that hole goes a cranking support part, which is attached to the chassis. Must there be some kind of rubber part between the two? Also there is a small hole on the radiator part, as if for a bolt, but there is no corresponding hole on the chassis?

[Henry Magno]

There is a rubber ring that is sandwiched between the radiator support and another plate with two holes. There should be two bolt holes or maybe two permanent studs on the support. See the pre-war parts book http://www.170220.org/uploads/Ersatzteilliste170V.pdf or the 170 Va parts book http://www.170220.org/uploads/170Va_Parts_combined022009.pdf.

It seems like some of our newer members don't realize that we have these technical resources available right on this site under "Tech References"

Thank you very much for your response, Henry! I have for a long time that PDF, plus have purchased a 1942 printed real book. Almost the same, but with a few differences, too.  I checked both, but never found a radiator shown. Only now after you said, I looked again and realized, that the radiator is actually there, but shown hidden inside the front mask. And of course, the rubber part and the metal part are shown, too! Now I see and it's all clear Thank you!

[Henry Magno]

This rubber part is readily available. I just bought one for the roadster we are doing.

I have a question for you. You have a 1942 parts book. I would like to know what edition it is and what RB numbers this book applies to. This is on the front cover or first page. I am trying get the MB archives to find the chassis number which is missing. The frame is stamped with an abbreviated RB number, which in full would read 10 136 036/xxxx. This would be RB series 035/036. Knowing the printing date of the appropriate book for that RB number would help narrow down the production year.

I think I have Ed. D which is too early for that series.

[Ted]

A pity, but there is no Rb Nr. Checked the cover, the back, the title page, inside the pages - no, nothing. The book is edition G and there is a date 15.1.1942, but that information is probably useless without the RBNr.

[Henry Magno]

Thanks Ted. Anyone have Ed. E or F?

[roadster36]

Sorry ,
here also G 1942 ;)and i always understand that it is the last and most wanted prewar ersatzteilliste.
and the list tels me that is correct   http://www.autogallery.org.ru/pmbtable.htm
And I have C 1938

Henry,
is the roadster build in1940-1942?

[Henry Magno]

I don't know either when ours was built, nor do I know whether any were built in 40-42. It's hard to imagine they would build a roadster in the war years, but anything is possible.

I asked Benjamin Kriwanek, who is a club manager for MB Classic to see if he can prod the archives to find our car. My inquiry through the US Classic center came up with nothing, but I don't know hard the effort was. I'm hoping that with a little effort they can cross the body and RB number to the chassis number.

Does anyone on here know this man, or have any useful contacts at the archives?

[John Nguyen]

Finally I got these rods fabricated in standard steel
