W123 Throttle pivot bushing inserts, brand new!
Making replacement throttle pivot bushings from polyurethane and oil impregnated bronze. Have tested many prototypes and they work great! Have a few people running them in their cars and they have nice smooth throttle movement.
Shoot me a message or Etsy link is below https://www.etsy.com/DMERCINC/listing/926478734/mercedes-w123-polyurethane-throttle?utm_source=Copy&utm_medium=ListingManager&utm_campaign=Share&utm_term=so.lmsm&share_time=16 10633206210 Last edited by Dutchbizzle; 01-14-2021 at 09:07 AM.

Very nice indeed and it fills an apparent void in the old German steel supply line

How does the material being used hold up long term? Is the longevity the same as stock? Longer? Shorter? OE MB is notoriously hard to emulate. Any plans for a different material? I see these on eBay in solid aluminum.

So they should be comparable service life to the originals, have a few months into torture testing them, hard to say whether they will outlast the OE ones since they hold up for quite a few years. I am playing with different material types as we speak, making some with Delrin core, casting a few, 3D printing some with TPU and more!
As for the aluminum ones, Hector Correa makes those and he is a good dude, but price point is a smidge steep IMO and I worry about deviating from the MB originals too far, they had reasons for going with rubber and plastic for that bushing (at least I think they did) Sorry for late reply, busy busy! |

They might be sourcing the part from a mfr in Taiwan and marking them up because the aluminum ones on eBay are about $35. Their design is also made in a way that it can replace earlier bushings.
I've tried to understand why MB would use plastics for this part. The bushing itself just fills the space and only turns as part of the assembly. Nothing actually wears out, the bushing just disintegrates. I'm not sure when CNC was viable for mass production. In the early 80's a chunk of aluminum that shape could have been cost prohibitive.

That's the standard lifespan for this part and many other OE parts from the era. Lots of copies of some MB plastics and most all MB rubber but no one can duplicate them to the point of matching the longevity. On top of that they lasted decades while being totally neglected.

I suspect MB mainly used the softer material to kill as much NVH coming through the throttle linkage as possible.
