I have an 83 240D and I need the large fiber gear in the sunroof motor assembly. Does anybody know of where to find one? My motor is fine, I just need the fiber gear, its teeth are worn down

The only place I found was here:http://**************.com/search/node/sunroof+gear

Thanks for the info. I checked it out and $96 for a fiber gear seems i tad high.

Junkyard or ebay. Buy the whole gear box.

i see the sunroof motors ripped apart in the PNP all the time with the large gear removed. but there are always several intact ones in the yards

Make sure your sunroof is sliding freely before you repair the gearbox, or else it will strip again. It is a good time now to clean and lubricate the rails on the sunroof, and probably pull the cable out of the liner and clean the dried/dirty grease and replace it with new. I need to do this on my 83 300D, and just haven't had time yet. I bought a used sunroof motor assembly on eBay for $52 shipped from one of the yahoos selling a bunch of junkyard MB parts.

The gear should not strip if the clutch is opperating properly.

I checked the archives and couldn't find a link on how to remove/clean the cable so I don't strip another gear. I'm guessing I take the liner off of the sunroof and disconnect the cable??? Any help is appreciated.

Thanks

How do you pinpoint the problem? Mine doesn't work, but I don't know if it's the motor, gears, cable or just the sunroof itself that is stuck.

X2 - one of the other dangers of an improperly adjusted clutch is that in addition to stripping the gears it can also over-stress the mounting points for the cable shell. When the sunroof stuck on mine the clutch was adjusted too tightly and it pulled so hard on the cable shell that it broke the mounting tabs off of it where it bolts to the back of the roof strut that runs across the roof (above the headliner). You can tell if the mounting tabs are broken if you remove the headliner panel of the sunroof and open/close the roof. If the cable shell behind the sunroof opening moves forward when opening the sunroof, or moves backwards when closing it, the mounting tabs are probably broken. If yours has that problem as well, send me a PM, I came up with a fairly easy way to fix it that doesn't require removing the headliner (and removing the rear window to get the headliner out).

The clutch adjustment is a 17mm nut (I believe that was the size - maybe it was a 16mm) on the shaft of the motor/gearbox assembly. To actually get to it you have to first remove the plastic cover that has the hex-head end on it - the part that put the wrench on in order to manually crank the roof open or closed. The clutch nut should be adjusted just tight enough to move the roof without slipping, but when it reaches either the fully open or fully closed position the motor should NOT stall - it should continue to turn - just at a slower speed due to the drag of the clutch.

BTW, I don't know what others are using, but I found that white spray lithium grease works very well for lubing the tracks.
