- Mercedes Crankshaft Pulley Harmonic Balancer DIY for Mercedes-Benz vehicles including W211 E320 and E500. Also applies to other Mercedes with M112, M113 and M113k engines including ML320, ML500, S500, SL500, C280 and more.
This is good preventative maintenance and you can see the rubber was already starting to deteriorate on our pulley.
There is plenty of information on the Internet about this repair, we put together this video to show you the tips and tricks that are going to make it a breeze to complete.
It's tough to fit a camera, light and wrench in this location, so we've captured videos of each step to guide you.
Of course, proceed at your own risk, and always work safely in a clearly lit environment. Thanks for watching, please like, subscribe and share if this video helped you!

Excellent exactly as you showed perfect
Thank you
John
You're welcome, John. Glad it helped!
Great video! Quick and to the point with some good tips and tricks. I have the same tool/pulley dilemma as well, so I will be doing some grinding, it appears, today when I take on this job.
Thank you! Good luck with your repair, let us know how it goes.
Great video, thanks mate.
Thank you, that's a honor from you! We love your videos.
I believe I have a m272 engine on a c300, would the procedure be the same?
Yes, the procedure is the same. The tool and part may look slightly different. Always double-check part numbers and instructions for your model.
Hej. What size wrench does the pulley bolt have?

27mm
hi, would this work on a 2011 ml350?
Yes, the steps will be similar. You will want to check the tool and crankshaft pulley are correct for your model. You should have the M272 engine. Leave a comment with tips for your model to help others that have the same vehicle.
What is the mileage on the car at this point?
We had about 199k on the car when we replaced the pulley. It looked like the original pulley! We've put about 500 miles on it since then with no issues.
can any body tell me what a M112 is? is that the W211 ???
M112 is the v6 gas/petrol engine, M113 is the V8 engine.

I HAVE A HARMONIC BALANCE WITH FIVE HOLES IN IT {2009 mercedes e320 bluetec 3.0 diesel. the pins in holder will not line up with the balancer i have. FIVE HOLES IN BALANCER.
Thanks for your tip which will help others with the E320 bluetec. If the three pins don't line up, you could try measuring to see if two of the pins will line up, then grind down one. However, it may best to look for another removal tool.
the pins on tool should be 72 deg
right on with that 72 deg . now how do i find the tool i need. i need too get my money back and get right tool...
@@michaelbrueckner3893 Yes 360/5 = 72. The tool we have is 360/3 = 120. We thought if you could shave the sides to get the 120 out to 144, but probably not. We've seen people weld their own tools before. There are also universal holders that adjust.
