I am finally going to get to that timing chain job that I have been avoiding for a couple of months for my 84 190E 2.3 gas motor.

What size allen socket do I need to get the chain tensioner cap nut off?

I dont want to rip the alternator out and then find out I dont have the right tools, only to prolong the job another week.

Thanks folks.
