Beautiful engine put back together


Tools: Removal tool, 27mm socket, 150 ft lb torque wrench, cheater bar, eye protection


Tool is absolutely necessary to get off pulley

My crankshaft pulley on my 2006 w219 was showing excessive vibration, so I figured I better change it before it goes altogether.
Following a Mercedes Medic tutorial, I bought the pulley removal tool and new pulley. About $200 total. First I removed the shroud and fan. Then I used the tool with breaker bar and cheater bar to loosen big bolt. It wasn't too hard. Then I put the new pulley on and torqued to 147 ft pounds plus about an additional quarter turn. Getting that extra quarter turn was the hardest part. Then I put her back together, fired her up, and the pulley ran smooth with no more vibration.

I just wanted to post to let others know this job is not really that hard. Just be really patient, but the correct tools, and carefully read/watch the online tutorials.
Attached are some pics of my old pulley, engine put back together, and the various tools I used.
