That works, Guscha. You see what I mean? I have no aptitude for this. A slotted bushing is still needed, right? And 2 rivets.

On the other hand, who says it doesn't take a Russian rocket scientist to figure this out?

My external harddisc makes trouble. Therefore here are first rough draft instead of a photograph.
The mentioned plastic bushes are too weak to be a lasting solution. Howard is the best helper money can buy - exceptions prove the rule. It has to be riveted. Well, I miss an important part to build a "kind of hinge" - so sorry for my poor English. But a picture of the mechanism in a ZIS will help. Just wait until the Russians come!

Confirmed.

Howard, Guscha,
Do you think the rivets could serve as the bushing? Or a bushing around each rivet?

That long slot looks like it's either for allowing movement or for making an adjustment. Would one hole be for a rivet (the round hole) and the other for an adjustment screw?

Joe

That looks logical. Is there anything else in the hole to keep the two arms together and centered on the ZIS? The picture in the parts manual looks like some kind of washer but it must not be a true view since it does not show the arm going thru. Are the arms made in such a way that sharp edges on the arm and hole would not dig into each other if there is no bushing or guidance.

EDIT Strike the question. There has to be something there or things would rattle to no end.

I've just seen your pic above. Step two was to find a technical term: abutment! The arm with the hole usualy has another small hole (at least the Soviet system) that works as abutment for the rivet (draft attached).

Sorry, but the only thing I can think of would still be some kind of bushing with a flange to fit the hole & a slot but that is not what shows in parts picture. Where are all the guys with 40-42 cars or extra regulators when you need them. Surely one is apart somewhere just waiting for pictures.

Howard, we should memorize this sentence as it marks the difference between Packard quality and Soviet soundness (solidity). Perhaps the opposition between the tension of the pull spring and the antagonistic hydraulic pressure works noise absorbing. Please find attached the announced riveted Soviet rattler.

Slipping the arm through the hole was a big step forward. And yes, wondering where 40 people are. From the wear pattern on the small arm, there was something round there. The way it's dug in, I don't think the inside of the big round hole in the primary arm did it. I think there was a bushing cutting into it.

I know we will be saying OF COURSE when we find out.

The ZIS has a center rivet.

Joe, how about this "contured disc" between both arms? The center hole hosts the rivet, the curved slot is to put the other arm through and the middle edge gives guidance and noise attenuation.
