Post Ignition switch replacement problems

Hi
I have read a lot of pages pertaining to the replacement of the ign switch and haven't found any for my 1984 switch . I need help i have to replace the switch now i have the instrument cluster out and can't reach the three screws that i need to get the switch off. So i tryed to get the whole unit out i took out the screw of a clamp that was holding it, thought it would come out then but now luck. What am i doing wrong. this is a 1984 190e 2.3. I also tryed to pull the ignition cylinder out i made a wire tool out of a coat hanger belveled it at one person said 70 Degres and one person said 45. it fits in fine, when pushed in it goes almost all the length of the cylinder. That didn't work ether won't come out. Does the black lock ring unscrew before i can pull the tumbler out?

Regards

To pull the lock assembly out from the steering column the clamp needs to be loosened (you did this already), and the key needs to be in the #1 position to release the steering lock and pin. It should then slide out of the column to the right and rotate it to clear. It will be a tight fit no matter what.

Hi,
The screw is removed does the clamp have to be removed. it looks like i might have to remove the ignition tumblers to get it to clear. does the black lock ring unscrew i tried to remove the tumbler with the home made tool and couldn't.?

The clamp doesn't need to be removed, but if you slide it to one side you can see the pin that holds the switch into the steering column. Did you have the key/switch in the #1 position before trying to insert the tool? They can be sticky when pulling them out. Otherwise, it will clear the dash, you may need to flex things a little. Mine was a pain due to not having a key for it, and the little pin that slides into the black tube on the steering column needed to be ground out. Your's should retract when the key is in the #1 position. You should be able to see it by looking under the dash. There is a write up here that has some good pics of what and where everything is.

Hi,
The key is in 1# position. the steering wheel is not pulled, the thing rotates up and down and hits the key hole but will not pull forward. I have tried to wiggle it for two days know. Something is still hanging it up. I don't see how it will clear the dash. The tumblers still won't come out. Have not found the articles you speak of.
Regards

If you have the black ring on it, I think you may have to switch to #2 position, insert a 2.3mm hex key to release the latch and unscrew the black shroud...while pressing in the hex key all the time.

Hi,
Thanks everyone for your replies. Today i got it apart.The pin on the side of the cylinder had to be depressed threw the sleeve to get it to move forward. The only means of doing this is to pull the steering wheel, where the pin is clearly visible. Pushed it in, pushed it forward spun it to the right after pulling the dash out a little as previously suggested. Bent the tin on the lip a little bit but it came out after disconnecting the wire attached to it. As for the black cylinder around the tumbler it pulls off with the removal of the tumbler cylinder and key. Reground the wire to 70 degrees and after a lot of wiggling it came out to. My problem was the shaft that turns the Ignition switch was broke off. Unfortunately it destroyed them both. Know the search starts for parts.
Regards

So how do you get the tumbler cylinder out? I fought with mine for about an hour before giving up. I followed the directions for removal from the service manual, but could not shake it loose!

Hi,
I found i wasn't down fare enough. Make sure the wire is at 70 degrees not two blunt on the ends. On mine there was only one springy clip on one side of the cylinder, but its the two holes at the bottom that release the black cover that it wasn't down fare enough. The release holes are approx 1 1/2 down. mine just poped open after pulling and wiggling on the key. You will feel it when it goes down all the way. Try measuring the wire each time to see how far you are down and taping on the wire with a piece of wood or hammer perhaps, not to hard.
Regards
