When did your harmonic (crankshaft) balancer fail?
 

Although this forum has a excellent long sticky thread initiated by benzmac concerning the failure of the M112 V6 harmonic balancer on models 1998-2000, I thought I would start a thread that simply asks people to enter the car model and year, failure date and mileage. This would be a simple thread to easily scan to compile data on these failures.

Hopefully Mercedes will someday treat this as a recall, and those that have paid to have it repair will be compensated. This thread could be a good start to having quick and easily obtained failure data. If your balancer hasn't failed, don't respond to this thread. The results should give us a clear picture of how many of us are experiencing failures and maybe a correlation can be drawn between model year and mileage. If you have questions regarding the problem, refer to the post by benzmac.

Dave, You beat me to it by 5 minutes, my topic was going to be. Who hasn't had balancer problems,and to please state mileage and model. Mine 99 C280 was developing cracks at 19,500, so i changed it myself. I tried the dealer but they said they weren't aware of any problems. Such B.S.

grapes11, as they say, great minds think alike. Some may think this is a redundant thread to the moderator's thread, but I think this thread could be quick and easily scanned to gauge just how many people on this forum have experienced this problem, and at what mileage and model. The other thread's great, but it requires you to read every posting to learn the details, and it may not involve a failure.

Dave, Guess it's you and me buddy. Nobody else seems to be interested. I would think this topic would be just as important as the original thread. And you're right great minds do think alike Let's just see what time does to this post. Jeff

I think this post has merit.
 

But most probably don't reply because they had already wrote up an exhausting response to Donnie's thread...

...I myself have also responded here and to another related thread in the ML forum.

And as far as my experience, reading the sticky thread prompted me to have mine checked...I was preparing for a trip. Hairline cracks were discovered and they replaced the part and charged me labor only.
