230 SL rear brake adjustment rings
« on: February 22, 2019, 18:57:41 »
I don't know the right for it, but I guess adjustment rings will suit.
How are these mounted at the pins?
They have slit holes and fit tight at a part of the pin, but how are they originally secured?
There is quite a force at it because of the compression spring.

Maybe this helps:
64 retainer
outer side of the shoe
65 washer
66 spring
67 washer
70 cotter pin

If you follow this link and get towards the end/bottom of the bearing replacement process - you will see pictures of the part you are looking at, I think.

Thank you for the help.
I'm aware of the order of the parts at the pin, but as you can see the ring is stuck at the pin.
And the spring is pre-tesioned, so how does it stay there?

I see - in the car we were working on it did not come off, it was one part with the backing plate if I remember correctly.

That part isn't supposed to come off - at least I've never taken one off or ever needed to. These things turn to adjust your brake shoes in or out and they require a bit of force to make them turn.

Yes I think they are pressed together just to stay in place.
I took them off anyway for rust prevention, so now I have to think about a trick to get them in place again.

Weld the cam to the pin?
Add material inside the hole by welding-like process (I do not know how would it be called in English - hardfacing?) and pressing? Or doing it to the pin.
Some kind of clip holding it in place?

Just thought starters.

Thanks for helping.
Welding will cancel the anti-rust protection, but I will figure something.
