I have to share my story from this weekend it is just too crazy not to share. I ran into the common crank pulley issue. I noticed under hard acceleration there was a belt squeal and the car just didn't seem to have as much power. When i went to a local car meet we were looking under the hood of my car and found that my supercharger section of my crank pulley had come off and was sitting on the shield underneath. I am very surprised this is all that happened. It never even threw the belt but did shift it a little. So needless to say this weekend is going to be very fun with having to replace the pulley.

Where are you getting a replacement and how much

I ordered one from OEM Benz parts it was $420 shipped. Best price i could find yesterday to have it for this weekend.

You probably already know this, but just in case... that is a one time use bolt.

Looks like the outer ring separate from the rubber. It is good practice to check on your pulleys once in a while, you would have noticed it coming apart.

If you can't find a tool to hold the crank pulley I made one that worked well for my situation. Let me know if you need to borrow it. Do not used any method that locks the flywheel. The bolt requires a massive amount of tq...

I am interested in renting out this tool from you. Thanks

I made a tool as well and can tell you that that last 90* take's some serious pulling power to turn that bolt !!!

Never torqued a bolt that much in my life. Took two grown men to get the complete 90 degrees.

LOL ! It took to grown men just to remove the bolt and that was funny in of it self !!!

What cnterline said. And remember that keyway is just to align the dampner….not to keep it from spinning. It's the bolt torque that keeps the pulley on and the extra pin install to help keep the pulley aligned and in place !! Break out those 5 foot pipes for torque !!

Looking for crank pulley part number for a MG E 55.

I ordered mine off whatever MB parts website had it for the lowest price. When I had this issue FCP didn't stock the crank pulley like they do now as i would have just ordered it from them for lifetime warranty purposes. I linked it bellow for anyone that may need it now or in the future.
