818 - Mercedes Benz windshield mono-wiper

[RM1SepEx]

Nice looking unit, the stock unit works well w/o cutting the hood as a single wiper too. What specific yr/model is the source of that Mercedes wiper unit?

It was used on many models over many years. I know of at least 2 versions of the mechanism as well. This one was from a 1993 190E. I think all of their models used the mono-post design C thru S.

The stock unit does not lengthen and shorten the path of the wiper to cover the full windshield, thus the overly complicated solution by Mercedes. Mostly I just always liked this crazy wiper and wanted to try and work it into my 818. I may still fail but going to give it the old college try!

I slightly disagree. Maybe it's a problem on mine but I think yours looks the same when parked, according to the pix in the other post. When the motor is parked, it is not at full swipe yet, once you turn on the wiper, the blade will move downwards about 3" and then upwards to wipe all the way to the other side. It does not park fully downwards so the blade needs to block visibility a little more. That's just too bad, I wonder if the Benz unit will do better on that.

What's interesting on your last pic Dan is that the blade seems to park low enough, but on the motor pix you can see the smaller motor arm-link is not at full angle (which is same angle as the flat bar on the motor that makes the blade swing).


EDIT: STATEMENT RETRACTED

I retract that statement. I agree with Dan on the Subaru wiper. More on my build thread in the next couple days (problem fixed).


@Ben you will update with more details on the Benz once you progress?

I will post what I find, one way or the other. It is still mushing around in my brain but hopefully something will pop out soon!
