I was certain this arrangement was correct, but it actually does not function the EGR valve regardless of throttle position.

have you taken the valve off and checked the functioning?
of course, even if it does, i've an egr valve that functions (the piston opens and closes), but the arm is broken, so it does not move the piston.
i also think there's a diaphragm in there that may be toast. others, like Steve and Ray, will know more about that.

Never mind. I had the tension spring and control linkage assembly reversed.

| Thanks, Steve. The B&W photo is from Bentley indeed. Procedures are clear; I just failed to insert the parts in the right locations |

Is the black bushing on one end of the rod stock Vanagon, or did you find a solution for broken/missing bits?

I totally violated thread policy.  That is actually on the 1981 Vanagon. The wealth of Type 4 air-cooled fuel injection knowledge is greater in this room. |

Well, this shows what happens when it's not located properly. I didn't make one where it functions properly after following the Bentley. In this video, the throttle cable is not yet installed.

I noticed and I love it! Didn’t notice the rods in the wrong holes though 😬
I’ve broken a few of those clear plastic bushings and wanted to know if you had a source for the black-looking bushing.

I’m not seeing how that direction matters, either.

OP mixed up the two levers on the throttle body, and TheSamba interpreted it wrong. 
Wasted Youth was talking about the throttle body return spring, not the EGR hyper-extension spring.

Edited for content and… grammar…
Yes, Robbie explained it correctly. If you look at the crappy black-and-white picture from the Bentley, and then my first picture, you could see that the rod and the spring are in the wrong locations.
The problem I was concerned with was not the EGR function itself or the rod, so I think I probably should have used more clear grammar from the onset.
When the rod and spring get mixed up, the EGR valve never functions because the cam on the throttle body doesn’t rotate that one when the throttle cable is advanced. And so the spring looks like it’s doing something useful, but it’s not.

Grammar is for schmucks. If everyone paid attention this forum wouldn’t be half as cool.

this was in Phil's photo. He might be able to answer your question. He was doing some rebushing of EGR arms at one time according to some 2021 photos. I think from the photos he may insert them then use a tool like what is used to fold a cloth eyelet over to make it hold in position.
