Hello, I'm in the process of removing my cylinder head but I'm having an issue with removing the cam sprocket to remove the timing chain, my 89 S124 is fitted with self levelling suspension which means the bolt holding on the sprocket is of a different design to a non-SLS model which is what is demonstrated in almost all manuals and guides I can find online.


The SLS connector that is attatched to the sprocked looks like it may have an allen head recessed inside but its quite hard to see, would anyone be able to confirm that its an allen headed bolt and if so what size key would I need to remove? I'm unable to just go out and check as the car is stored away from home...

Thanks

Any way you could get another pic with flashlight shining down hole?

Another option would to be purchase a set of metric allen head wrenches to take with you next time you head over.
