123: Firewall bushing for throttle linkage busted

Hi, the throttle linkage bushing on the firewall is broken on my 1984 300D Turbo Diesel. The joint in question is between the vertical rod(connected to the accelerator pedal, I presume) that rises parallel to the firewall and the rotating linkage that connects the rest of the throttle linkage. The whole piece will fall apart if you touch it wrong. It slips out of the bushing in the firewall occasionally. I do not drive this car at all, by the way, but I'm preparing it to be later this year. I think I got a great deal on this car ($900) because the previous owner did not spot this linkage problem, and thought the engine needed major work. I hope it doesn't. I've put 14 miles on the car since I got it.

Does anyone have any idea which parts need to be replaced, and where I can get them? Is this a common problem? There isn't a tutorial for this issue.. is there? Thanks!

Yes, it's a common problem. The nylon bushings get old and brittle. The only safe thing to do is replace it. Unfortunately, you have to buy the whole assembly as depicted in post #2. You can't buy just the bushing.

Darn. Is pick-a-part a bad idea, then?

Why replace a twenty-two year old part with another 22 year-old part? Of course, you might get lucky and find one that had been replaced the day before the car was wrecked. (I'm never so lucky.)

But that part is not one to fool around with. A failed bushing could cause the accelerator linkage to jam. Then your car might be headed to the pick-a-part lot.
