The Fluidampr harmonic balancer also fits many European and International models equipped with the M57. (scroll down for an application guide)
BMW recommends replacing the harmonic balancer bolts everytime you remove them. The harmonic balancer bolt part number is 11-23-2-247-932, and it's available in this listing at a discounted price of $20 per set of 4.
Clutched Pulley Conversion Kit for Alternators:
Shortly after releasing the Fluidampr we quickly learned that most vehicles had a noise/vibration on the serpentine belt. This vibration is caused by the alternator having a solid metal pulley instead of a decoupler pulley that is found on many alternators. We will be providing these decoupler pulleys with Fluidamprs, this will eliminate all noise and vibration providing you with an exceptionally smooth running and quiet vehicle.

FAQ SECTION: This will be updated as time goes on
Q: What does the Fluidampr unit weigh in comparison to the stock unit?
A: The Fluidampr unit is 15.6 lbs. and I just weighed my stock unit, it is also 15.6lbs
However, with any viscous type damper there is a rotating weight factor as during engine operation our internal inertia ring stays suspended in the silicone fluid thus relieving the crankshaft of this weight. Rotating weight for this unit is 10.4 lbs.
Also, it is important to note: when dealing with a harmonic damper (balancer) you must have the proper amount of inertia mass (weight) in order to control dangerous torsional vibrations. General rule of thumb (there is a limit) a heavier damper will do a better job at absorbing crankshaft twist thus reducing the amount of vibration being put back into critical engine components. Time and time again we have done h.p./torque comparisons vs. lighter OEM dampers and put down higher h.p./torque numbers on the dyno as well as overall torsional improvements.
Q:What is the correct bolt torque?
A: 40NM (29.5ft/lbs) + 120 degrees; these are torque to yield bolts.
Q:How do I use the belt tool?
Q:Where do I insert the crankshaft lock tool?
A:Driver's side of the engine block, above the oil pan, under the crankshaft sensor. There may be a grey rubber plug you need to remove. Press the tool in the hole, while turning the crankshaft, the tool will find a hole in the flexplate and keep it locked.
DO NOT forget to remove the tool before starting the engine!

This upgrade is a must and make sure to get the clutch pulley and special tools with the Fluidampr. Install was easy 2-3 hrs. I have a rear view mirror which is also a camera, it would shake so much because of the diesel engine itself and the diff brace. After the Fluidampr and clutch pulley install that has changed! The rear view mirror is really smooth now, very little shake, I still cant believe the change. The engine tone has changed as well little lower and seems quieter, unless you go full throttle, :)
There is no noise or belt issues. Well worth the money and the security of knowing it is not going to wear out on you within 100k and leave to you stuck somewhere.
Got my Fluidampr Harmonic balancer in today and installed it in my apartment parking lot in just a couple of hours. I ordered the full package with the belts, bolts, clutched alternator pulley and tool rental. I have to say, i am extremely pleased with the results. Car seems much smoother than before (even way before HB problems started). Engine is visibly smoother at idle with less vibration and sounds slightly quieter (Maybe some placebo effect here). I was a little nervous after reading some discouraging dialogue on other sites but there was clearly no cause for concern. This is a great set-up and I highly recommend this kit. Even if you aren't having problems with your stock HB, if you are over 60k, go ahead and replace it... those things are doomed for failure and can leave you stranded. (BTW ...definitely rent or purchase the special tools listed. They made things very easy).
