hello to all, I am preparing to change out the Timing chain guides on a 1991 560SEL. I purchased an excellent guide book from **************.com titled "Preventing Catastrophic V8 Engine Failure". On page 19 of the book Step Five, "Prepare your puller tool for removing the two steel pins holding each chain guide in place....." "You will need two or three different length bolts with the proper thread and a few different length spacers. The spacers must have a hole big enough for the head of the steel pin to go through it." The author did not specify the thread SIZE of the different length bolts. anyone know the size needed? Also, in reference to the spacers, where could one find those? Thanks, Husky

if anyone knows the the above information, please email me ASAP. I need to get this engine back together! Thanks for any help, Husky

When I replaced the head gasket on my '93 190E 2.3, I used a spare Belt Tensioner adjusting bolt that I had on hand. I went to the hardware store and purchased a couple of nuts, ( I think they were 6mm). Then, with a nut screwed onto the bolt, along with a washer and a socket for a spacer, I screwed the bolt into the pin. I then proceeded to turn the nut clockwise and the pin came out into the inside of the socket.
Does this make any sense?
It worked perfect on both pins.

Dave

this makes sense if the pin holding the timing chain guide on a 1991 560SEL is 6mm. thanks for the help....anybody know if a 6mm bolt will work on a 1991 560SEL?

received an answer today from **************.com special thanks to them for helping out!
