Yep........gone.......it's sitting on a shelf in the garage.

You need a 25mm wrench and a set of channel locks. The wrench goes on the large nut and the channel locks hold the ALDA on the smaller nut directly below the ALDA.

Turn the ALDA counterclockwise and the big nut clockwise to break the lock between the two. Unthread the big nut and remove the ALDA. Plug the pressure line and you're done.

That W124 will be the proverbial rocketship when you get the ALDA removed. You won't believe it.

Brian,
What did you plug the pressure line with (is it very high pressure)? Didn't this leave some type of fitting where it was removed that had to be filled with something? What.

Another thread is looking for a summary of all that can be removed:

Maybe you'll join that thread also - please.

Sorry for the above post. Most of what I asked was on the next pages of the thread. Being a newbie, I saw the submit square (actually one at the bottom of every page) and thought I was at the end of the thread. I'll try to be more careful.

OK, I've now read the entire thread and I appreciate how often the regulars are writing the same responses. The only confusing part was trying to keep straight if the comments applied to all models, 123, 617, etc. Now I'll commit to some wrench and mightly vac time and see if I can't fix several related problems.
Thanks,
Charles

The thread is dedicated to the 603, but, Lance and a few others have also removed the ALDA on the 617. The general consensus is that the 617 will be prone to smoke unless you're very careful with the pedal. YMMV.
