Hi Everybody,

I am from Belgium and rebuilding 500E 1991. I damaged the Oil Chain Guide part nbr a1161811059. I went to Mercedes dealer and the part is not available Enymore. I Search the internet and at the moment nog Where to find. I even order in Singapore but get message not in stock. Also from febi not available.

This pease is also to find in the V8 s from the 80s . Example 380sec 500sec and s klasse. Without this part I can't prepair the engine to put back in the Car. Is here anyone WHO have an Solution to this. Greets G.
 
I can't reuse becouse I broke it with Taking off the Upper Oil pan. I dident see it and it was sticking out a Little into the Upper Oil pan. I bay the complete Chain and Guide kit but the Oil Chain Guide was not include. And went to Mercedes but out off Stock. I just find some site on internet WHO have it in stock but not sure it's a scam or not. . CA. I supose it's canada.
 
Wow 50€, I paid 2$ for it two moths ago. I think that this part could be easily milled out of some 17mm PTFE sheet. I don't know if there would be that much demand for it, but I can ask around. If someone needs one in the future PM me and maybe I will be able to come up with something.

This looks like a perfect candidate for 3D printing to my mind. Would be cool if you ended up replicating these @Kridre - so much stuff going NLA....
 
@TimL Not all parts should be 3D printed, I would have trust issues with 3D printed oil guide even tho I know that parts made from PA powder are really strong. I have spare brand-new guide to make 3D model out of it. If is ended up changing my work place in few months, maybe I will have access to CNC milling machine. I will come up with something.

Also I can 3D print this guide of PA-12 using FDM printer even next week, but who would be willing to be my test subject? :scratchchin:

Good point @Kridre. Who wants to gamble on 3D printing with their own engine? 🙂
 
@geert If you also need to replace the spring that pushes the guide, I have some available. They are custom made of 1.0 material, where original is 0.7. During my engine rebuild last year I was not able to find that spring so a local springmaker manufactured them for me.

Hi, am from Hungary, European Union. I own a Mercedes 126 560SEC as well. The engine has been restorated recently, but unfortunatelly the mechanic guy lost an essential part, namely the A1161810793 spring. I would be happy to buy one if you still have it on stock. Please, let me know if available. I pay with bank transfer prior to get the part. Waiting for your kind answer,

Regards,
Attila

If anyone still needs this part i found a contact willing to start reproduction of this part if theres demand from at least 5 people
 
I don't wanna be rude/impolite but there are several things to be consider.

I believe that the material is the 1st issue. I don't know does anybody know what is the material if the original part. Since it's crucial item I assume that repro's should have at least similar material properties as the original one. You don't want to blow your engine.
A friend of mine just recently contacted several those repro part producers to quote what material they are using and first issue was the temperature resistance. It was quite far from original one..

But if you can find similar material or at least similar properties I bet that there is a market for the repro's.

Good luck for the reproduction!
 
No affiliation - seller in USA has reman guides made from "nylon 6/6". Wonder how that compares to the original material. $105 USD each.

:update:

@MercEdi posted here that this tensioner rail is available from Mercedes again!

Online RevParts dealers in USA still show this as "Discontinued". It will take a while for each dealer to manually fix their website. In the meantime, you should be able to order one by contacting a live person at a dealership. If anyone finds out current pricing (MSRP and/or discount), please post here.

Just asked price from the local dealer.. 47 € !!! Insane.

That's half the price of some off-shore reproductions on eBay. The folx who invested in the repops will likely be sitting on that inventory for a long time once RevParts fixes their website.

BTW - I believe this part is only $22 USD MSRP in USA. Odd that it's so much higher in Europe.

SWEET! That's a lot of rails.

Would be great if someone can confirm the new mb ones are good. 16v community recently was greatly disappointed with mb repros for the 16v chain guides which are deformed/unusable. Reordering has turned out with the same crap.
 
Just for the curiosity if you buy new part from the dealer and that chain guide will be installed to the engine and later the engine blows due to the failure of that repro part by MB so will there be any goodwill or warranties by MB?

I would assume that if the MB reproduces a part it will remain the same standards as the original part has? :scratchchin:

MB will warranty the chain guide, I think the warranty period is 1 or 2 years. The rest of the engine? Nope.

It SHOULD be equal quality / performance / longevity! The 16v (M102?) anecdote above is concerning though.

:klink:
 
I was able to place an order through the Classic Center. I've attached a screenshot of the order below. My email was answered by Jon Siggson, email: jon.siggson@mbusa.com
, who was very helpful and told me that the order would take 7-10 days to arrive (it ships from Germany). I asked his permission to mention his name and contact information in case anyone here wanted to order the part. I'll post pictures once the part arrives.

Here are some pics of the new mb ones that i got in December 2024. @Rouven036 Maybe you can tell something from the photos? To me they look and feel fine.

As per the photos, the tensioner rail looks OK. I would de-burr the casting ridge on the running surface with a sharp blade and check if it moves smoothly on the carrier pin as well to see if it is straight, I.e the chain runs properly in the guided channel or let's say the center of the chain rides properly on the center.

Warranty wise, a consequential damage can usually be claimed, but an official dealer must perform the diagnosis. Question is what would be the outcome as a new motor or some parts are NLA...
 
Would like to mention i am experimenting with a M103 tensioner as when they were nla i didn’t exactly have time to wait and no money(college). I suppose during my first oil change i could replace this with them being available now. But nonetheless completely aware this is incredibly dangerous to the engine and against all advice, but so far so good. Will be sure to update when my chain grinds the broken bits to dust. As of 2/5 i have about 750 miles on the engine.

About two years ago during one of my many M119 restorations, I ran into the issue of the oil pump chain guide being NLA and at the time there was no news of MB reproducing them. I ended up 3D printing a prototype for fitment and seeing if I could improve upon the design at all.

After confirming fitment and the correct dimensions, I had a few cut out of Nylatron GS (Similar to Nylon 6/6 but with better wear properties). This is a common composite used in racing applications for chain guides and other components. It is a robust material and its strong suit is the embedded MoS2 particles which act as a dry lubricant and can withstand loads and mitigate wear.

I then opted to install a (snug) press fit bronze bearing/bushing to help with the quick movements the guides sees when rotating on its locating pin. If I were to do this again, I would omit this bearing for the reason of engine oils that can become acidic from combustion byproducts. This could corrode the bronze, but proper service intervals also answers that problem.

The reason I opted for it the first time around was because the waterjet cutting that I had done for me did not result in tight enough tolerances, therefore requiring a bushing or complete redesign/cut.

If we could figure out the material these new repro guides are made of, it would put a rest to this issue. As long as the material is right and there aren’t obvious signs of porous casting/injection molding, the part will work just fine for a long time.

The R129 I installed my DIY guide into has been daily driven for two years, seen about 15K miles and hasn’t had a single issue.
