ml320 window slider
Description
I used a stainless "Everbuilt" home depot brand stainless screw, and it the head was too big for the original STL. So I remixed it. I had more difficulties with this than with the original, designed for the w126 instead of the w163 because there is less room in the door cavity in the w163 for a 1 inch screw. Like the original, you will have to drill out the original mounting rivet on the end of the regulator arm, then drill the hole out to 5/16". I used a 7/8" screw, attached one jam nut inside of the regulator arm, and the other on the outside of the regulator arm, secured with a lock washer. In my implementation, the screw head rotates in the plastic slider, whereas the original remixed design had the regulator arm rotating around the screw, and the screw secured to the slider. My thinking is that I'd rather have metal rub against nylon than metal against metal. Is it better? Time will tell. I had to grind down the 7/8" screw, and a bit of the outside jam nut to get this to fit properly. See the picture looking up inside the door cavity for a picture of the unground nut hitting the door. Also, if you end up letting the window slide off the side track (easy to do), the easiest way to get it back on is to take the green slider off the window track, set it in the vertical track, and then set it back in the track directly attached to the window. Overall, this should be a sturdier replacement than the original, and will let you avoid drilling out approximately 7-8 rivets to replace the whole regulator. Parts needed: 7/8in (or possibly 3/4) x 5/16in flat-head screw (90deg countersink) 5/16in jam nut x2 5/16 lock washer Source remix design file for FreeCad provided.
