190SL Air Filter Element

I just opened the air filter housing to check the condition of the air filter on this supposedly "professionally maintained" car and found an empty container. Would somebody with a 190SL (ours is a 1961) be willing to snap a photo of the air filter element and give me its dimensions?

There does not seem to be an air filter element seating sufrace on the bottom 1/2 of the housing that I expected to see assuming the filter element is round.

Am I missing some parts?

Thanks!

Searching around it looks like the 190SL air filter is made of unobtonium. cant even find one online anywhere. I'm sure the stealer will sell you one for $$$$

Have you found this yet, it has a few good diagrams of 190SL?

Go down to auto parts store and find filters that fit? Consider stacking 2 or more to fill available space?

"there is no filter cartridge in there .it s all in the top part , wash ."

Agillot,

If you look closely at the picture of the top part you will see through the perforations to the inside of the lid of the top part. There is nothing there to wash. There may have been something once upon a time but it's not there now. Obviously some "professional" mechanic that my mother in law trusted simply threw the original air filter element in the trash, closed the container back up and charged her for a new air filter. That's why no "professional" mechanics touch any of my cars except for doing a smog check. I even do my own wheel alignments using a simple but effective camber gauge.

As can be seen from the photos both the top and bottom halves lack any parallel surfaces to seat a conventional donut shaped paper element and the base has irregularaties at the mounting holes where a round element would want to seat. I have machining and welding capability at home so I can fabricate something but I'm a much better copier than inventor.

Simply dropping in a round element is not an option because any element big enough to give only filtererd air to the perforations in the top 1/2 would both block the intake snorkel opening and not seat correctly in the bottom 1/2.

It's possible that if someone were to post a picture of what is supposed to be inside I could find a close match at an auto parts store. Surely someone knows what is supposed to be in there and will be kind and post a picture.

Rumb,

I live in such a rural, mountainous area that there is no high speed internet here, only dial up. I tried that link you suggested but my computer was unable to open that large pdf file. I will try at the public library.

Rumb,

I was able to open that catalog pdf. There is no air cleaner element listed, just a top 1/2 to bottom 1/2 gasket, support strut mounting kit, and air cleaner to manifold hose.

Being a street rodder at heart I may make an air intake plenum out of aluminum square tubing that attaches directly to the Weber carburetors and uses a modern high performance air filter element that breathes cold air.

Guys, I got the answer to this question from Jim Miller, the MB parts dealer. Here it is:

Hello Ray,

This bring back memories.

The original filter came with horse hare installed in the upper section between the top and the screen with large holes.

The filter was cleaned with kerosene and then motor oil was applied to act as the filter.

The top screen has to be cut out and replace with a modern disposable filter or some place

A foam filter behind it and apply a modern oil such as used in current day filters.

The 190SL group may have additional pictures to help.



This was a 1950’s design.



Jim Miller


So, now I can figure out a way to mount a readily available inexpensive filter into this housing with zero guilt. When completed this conversion will be visually undetectable.

While doing some research on cleaning the air filter of a 1961 190SL, I stumbled across this thread. Waldbaum's last post is on target. Attached is a photo of my newly cleaned and oiled filter, for reference. Fortunately, the filter material is in good shape.

I would contact the Classic Center in Irvine. I'm sure they'd be happy to tell you what they use for the filter.
