Antenna help ! 1997 Mercedes S600
 

Need some help with my 1997 Mercedes S600 sedan. I purchased the car with a broken power antenna. The antenna motor runs fine. So far I have purchased a replacement antenna as well as the following parts. I know the parts are suppose to be for this vehicle, but the install does not seem to make sense. There does not appear to be anything that will stop the antenna from coming out all the way. To me it just need a piece that covers (screws on) so antenna will stop when raising. See attachments. Any advise.

Welcome to the forum.

From all the W140 restorations I have done. Any Antenna repair I have done the whole assembly has to come out from inside. The grey paneling comes out. The Audio amp along with the holding bracket, and you will see the black antenna assembly.

The decorative cap snap in from the outside, and grips the barrel rubber gasket at the top. You will need to wind-up the antenna from the inside along the big plastic gear. The plastic Stub on the big gear will break that hold that single turn spring. I've never bought a new gear but fixed the stub with a bolt

There are two flavors of these antennas. The early till mid year cars have everything enclosed in the black plastic housing. The mid to 99 cars have the electronics separate to the mechanical parts like this..

The later cars suffer from corrosion problems due to the barrel rubber gasket at the top of the antenna getting hard.

The coupe W140 cars have a black rubber decorative cap, but here is a exploded diagram that may help.

Also if its not been said in post above .Remove the mast and drive from the wing .On the bench open it up and clean out the boroken bits from the drive .The drive is the part fixeed to the bottom of the teliscopic mast .If you feed it in with broken parts inside, it will damage the new one .
