W126 91 300SE window sliding jaw

[sixto]

I've read a number of threads on replacing sliding jaws. Mine broke into pieces so I had no problem removing it. Unfortunately the threads don't offer details or a visual of what installing a new jaw entails. Do I put the new jaw in the rail then attach the actuating arm? Do I attach the jaw to the actuating arm then reengage it in the rail? Where does the rivet go? Is the procedure even close to what I described?

Thanks,

The piece that is replaced is the sliding foot that goes on the end of the regulator arm.

The regulator must be removed from the door. The old rivet will be still in the arm. The plastic will be broken from it. The peened portion of the rivet must be ground off, then the body driven out with a punch. The new piece will add much to the understanding of whats next.

The rivet is built into the plastic foot loosely and the head of the rivet is recessed into the foot. I place a 3/8inch punch vertically into a vise. I then place the foot over the punch with the head of the rivet setting on the flat head of the punch. The small end of the rivet will be facing upward. Place the hole in the regulator arm over the rivet till the rivet protrudes. This whole arrangement is now held steady by firm pressure downward with the arm against the hard punch face. Use a ball peen hammer to mushroom the end of the rivet till it is secure.

Replace the regulator.

I have been told that on a 201 chassis the regulator must be replaced if the sliding jaw was broken. I questioned the fact that I was able to purchase a replacement sliding jaw as a seperate part and never received a reply to my post. Is the procdure similiar? Do I need to go back and purchase a new rivet for the regulator as my replacement sliding jaw did not come with one. Thank for your help.
