The old modulator on my 1981 380sl has a small metal pin that fits
into the receptacle on the transmission. However, the Mercedes brand
modulator I just bought to replace it comes with a separate, long
plastic pin with a little wheel and nipple on one end. Can anyone tell
me if this is the correct part and, if so, how to install it.?
Thanks very much in advance, and Best Wishes for a Very Happy New
Larry, that doesn't sound right. They built the 107 chassis for many
years and many technology changes. As I recall the early model metal
vacunm modulators were never replaced by the newer version plastic of
which there were many different versions.
If you can supply your complete VIN number I may be able to verify the
correct version. The aftermarket suppliers often don't have the
sophistocated cataloging of the Manufacturer resulting in errors.
You may post your VIN here or go to my website and send it there.
Thanks for trying to help, Les4Parts. As it turns out, it is
definitely the right modulator, since I found a MB Bulletin explaining
that the plastic extension was designed to account for expansion and
contraction at different temperatures.
What I need to know now, then, is how to install it?
Thanks for any help.
