Well I need your help again. My ignition is showing its age and twice now it has been a fight to get the key to move past the "0" position.

I've researched the archives, and cannot find any information on how to remove the tumbler specific to the W140 body. Lots of information on the E and C classes.

At this stage, I have successfully removed the plastic housing but am left with a 1-1/2" hole with the ignition switch bouncing around in it. I have the dealer's universal unit in my hands to compare against, but there seems to be a plastic or steel boot wrapped around the ignition switch/tumber assembly. I can't seem to locate any holes in the boot that would allow me to get to the tumbler release latch. It also appears that I have to remove the key to seperate the boot from the assembly.

I need the geniuses of the board to assist.

Thanks

Ron

The ignition tumbler on 140's and 129's are not designed to be replaced. The black metal sleeve that is encasing the tumbler does not have release holes like a 124, 201, 126 etc...it's a one-time deal. Once it's installed it won't come off unless you grind it or cut it off. Not the best idea for maintenance, but excellent for theft prevention. Unless you want to cut the sleeve off, you will need the ignition switch/steering lock assy along with a new sleeve and tumbler to repair it correctly. Good luck.

If you send me your email address I will email the video on how to remove the tumbler on the 129/140 chassis. It is not easy but can be done.

Great video about the switch removal. Sure makes it easy when the dash isn't there though. Regardless, it does help.

Thanks for the link

I saw a service bulletin that the cylinder can only be removed in position 1, with a thin wire used to release the catch, and pull out the cyliner. The replacement is also installed in position 1

Peter:

Trust me when I say its not as simple as that on the W140 or W129's. I'm personally not looking forward to locking the steering column in place by accident when I attempt the replacement.

Do you want me to post the video on how to remove the dash? ha ha.. It is a lot of work, but when you know what you are doing it sure makes it a lot easier. I repaired my passenger seat in my 129 on Friday and if I didn't have the instructions I sure would not have been able to do it because those seats in that car are really something, I think they weigh 500 lbs and they are held in with 8 bolts, you have to remove the cushions to get at them, I would have never figured that out on my own. I think in the video it shows you how to remove the electrical part of the switch and the locking mechanism, do you have to replace the locking mechanism too? If you just have to replace the electrical part that will be a lot easier, although there is nothing easy about a 140, they are wonderful beuatiful cars with more stuff in them than you will ever need, but working on them ain't fun! Take care and talk at you all later!

Bump.

I need to replace my tumbler/lock cylinder. I have the assembly removed and the protective cover off. How do I get the tumbler out of the sleeve?
W140 and apparently the same as R129 - it has a 129 part number.

Well nevermind - it was obvious after all, I thought it might be since no one ever mentioned how they got it out of the protectectve sleeve. Anyway a straight rod (coat hanger) through that little hole below the 462 of the part number pushes back a spring loaded clip and releases it.
