    Thread: My Fluidamper was out of Balance...

    1. 10-09-2019 04:01 PM #1
      The good people at Double J had a machine shop test my fluidamoer vs. a stock pulley and the Fludamper was not balanced spinning on it's own. Pretty interesting info considering that I have had issues with vibrations and bolts backing out...

      Interestinggggggggg........ i have a neuspeed i wanted to shed some weight. If that heavier one from fluidampr isnt balanced that thing could be very forceful in throwing stuff off. Did you feel noticeable vibs? “Nvh”

      well, I had a series of clutch issues... bolts backing out and then catastrophic failure. Another guy that had a DKM twin disk got a Fluidampoer and his clutch failed right after too.. It is a common denominator is some clutch issues. I then found other loose bolts later as well including the motor mount bolts... So something was going on.

      Isn't that the point of a Fluidampr? Whatever viscous fluid inside is going to get flung around but I thought the idea was it's out of balance in a specific phase.

      No the point was added weight in those specific spots in the wheel to oscillate the vibrations a bit more. If its not accurate in doing so it will make it much worse.

      “The Fluidampr replaces your crank pulley to control the harmonics through all RPM ranges of your engine. The precision machined and balanced internal inertia ring inside the precision machined and balanced housing is constantly shearing through the silicone while the engine is turning, tuning to the harmonic frequency bandwidths that your engine is producing real time. Rubber (elastomeric) dampers are only tuned for a specific narrow bandwidth of harmonics and they cannot tune up or down to what your engine is producing. They also wear out and have to be rebuilt or re-tuned frequently. Our Fluidampr products never wear out or have to be re-tuned, as they are constantly balancing the engine to max efficiency via the internal inertia ring. Fluidampr also helps to calm down the chatter associated with double disc clutches.”

      No, it doesn't get 'flung around', it shears to absorb harmonic differences between the inner and outer rings. It works basically the same way as a dual-mass flywheel, but it uses the fluid instead of springs.

      Has that person had their fluidampr checked? Was the issue brought up with Fluidampr directly?

      Looks like we found the cause of the vibrations... Bad Thrust Bearing.
