OK, I got the switch off. As predicted (not by me), there is no sign of internal shorting. Oh well, I always wanted to know how to take them off anyway! Back into the trunk I go, I guess. What a grimy mess. For those who want to know, the tricks are to remove the crossbrace and the speedomete

There is a notch in the actuating rod the bolt fits into. The lever will NOT come off until the bolt is out. This is true of several other "pinch bolts" on MBs -- the steering knuckle to ball joint pinch bolt on the S124 chassis comes to mind. Peter

Pinch bolt has to come out completely, just loosening it won't work. Man, I wish I have known this VITAL piece of info two years ago when I was doing the NSS job for the first and only time! Kevin in Hillsboro, OR 1983 300SD 266K miles, Ursula

Is it harder to remove the NSS on a later W123 than the one on a '77 300D? It didn't seem that hard on that car, just two 10mm? bolts and the bolt on the shifter arm that clamps to the rod sticking out of the tranny. The hardest part was getting the arm off without breaking the two ears and/or

Unplug switch -- some have a rotating catch, others just pull out from the font or side, depending on style. Three screws or bolts, and you must also remove the pinch bolt on the shifter lever and pull it off. Pinch bolt has to come out completely, just loosening it won't work. The sheet met

Right angle screwdriver if you have slot head screws, and replace them with hex bolts. How many? Once removed, does it pull straight out, or are there tricks to it. Remove electrical plug first? I tried to liberate a junkyard switch at the U-Pull once, and only ended up ruining it IIRC. Didn

Anybody know the trick for removing the neutral safety switch on a 123? I've got an intermittent fuse-blower on shifting into reverse, and I suspect the switch. I'd like to take it off and examine it. If it's toast I suppose I'll get a new one, but I'd rather not kill it trying to get it off.
