Title: Name of bushing
Post by: Janse on 27 June 2019, 11:17 AM
Hi. Can someone helt me find the right bushing? It sits on the firewall and is used to center the rod that goes to the carburetor, and comes from the gaspedal. My local mercedes dealer could not figure it out, but provided me with the part number 116 301 02 97.

Looks about right. Any ideas who has that part?

Sorry that part is NLA.  No sign at all of any  being available on the interweb.

Looks more like #78 to me. #70 is a dust boot that #57 goes through.

Boy this one is super NLA. Tried about every trick in the book, only to find it's been NLA for at least since 2011, and who knows how much longer. How important is this part?

If this is indeed the boot, you will find this part on any W126 usually in good condition, where the accelerator rod passes through the removable firewall. The later ones are made of a different material.

I'm pretty sure that 78 is the ball that sits in a kind of socket on the firewall.  It allows the angle of rod 76 to change according to gas pedal position.  Anyway, if the part is 78 I doubt it's NLA.  I bought one pretty recently from local MB dealer.

Yeah, I think the ball/bushing is what he's after, unless I misunderstood.

Yeah, I think I am also missing #81 and #83. Did not know there is supposed to be a spring there 🤦‍♂️

Does anyone have a picture of this?

By coincidence I do have a picture.  The long shaft is 76.  The spring, obviously, is 81.  83 is just a washer that backstops the spring and sits between the shaft and bushing 78.  78 is not really visible.  It sits in a ball socket on the fitting on the firewall.  When I got my car it was gone for some reason.  The linkage was sloppy, as you can imagine.

The round ball shaped bushing is missing in this picture........or am I missing something?

It's not missing, just very hard to see.  It's directly behind the spring where it sits in a ball socket.  It's dark back there and the socket is recessed so it isn't very visible when it's in place.  But it's there.  If it's missing the shaft will wiggle around.

Ah ok I see it now......wayyyyy back there.  However, it's in the wrong location.  The round plastic bushing is supposed to sit in the front cup of the metal bracket welded to the firewall, not behind it.  Change that as soon as you can.

Nice catch!  You're quite right.  That picture was BEFORE installing the bushing.  It's now it is indeed in the cup as you describe.  Sorry for not checking, should have sent the "after" picture.  :o
