The for the fix comes from badgator over on peach parts but he did not give details nor pics.
"I used a pvc pipe fitting I had in the garage, using the metal bracket outside, ID worked, OD had hex? to hold in center, cut off to fit length, probably cost .69 cents.
All it has to do is center the throttle shaft in the bracket and not bind."
Also the part has several names it is called by and this is some of them:
84 300D W123 Fire Wall Throttle Linkage Pivot Bushing Part 123 300 13 40
Firewall Throttle Linkage 84 300D, Accelerator Linkage Pivot Mount,
Mercedes-Benz Pivot Mount - Accelerator Linkage,
Mercedes W123 240D 300D 300CD 300TD OEM Throttle Bushing 123 300 13 40 Part #:

The 3/4th inch PVC Pipe Plug cost was $1.20 and you will need some suitable epoxy and a 5/16" drill bit if you do not have a 8mm Drill Bit. The Bushing comes hollowed out on one end.
The exterior rubber part on mine was OK so I am not fixing that. The plastic ball however was falling apart. Mine has 2 black bushings inside of the Plastic Ball that came out easily and you need those.
Some of the instructions are on the pictures. Pic of the parts.
I used the 2 black bushings and I oiled the back shaft on the drill bit so glue would not stick to t and I glued the 2 Black Bushings together to make it easier to assemble later.
What you end up with when the glue has dried.
I centered the black bushings in the hollow area of the Pipe Plug. I filled in the empty area with slow curing JB Weld. I used the slow curing because it will flow down into the empty area. The fast setting epoxies might not flow down to the bottom before it starts to set.
There is no picture of this. When the Epoxy was cured I used the 5/16" drill bit I inserted the bit into the black bushings which acted as a drill guide and drilled the hole all the way through the Pipe Plug.
5/16" leaves the hole a little too tight so I used a small pocket knife and enlarged the hole only in the PVC pipe plug plastic. Then I inserted the Pivot Shaft and worked it around till it was as loos as it should be.
I inserted the Pipe Plug into the metal mount with a little glue under the lip to hold it while handeling.
When that dried I flipped it over and filled in the area around the Pipe Plug with JB Weld slow curing Epoxy. Also in the picture you see I had found a Washer to take up the space of the protruding shaft.
Finished but notice that the collar is thicker on the Pipe Plug. However it causes no issues.
I installed it and test drove it with no issues. Will have to drive a longer amount of time to be sure.
