Around the first of the year, I ordered a Fluidamper for my '03 from Genos after reading about the positive reviews here and on other forums about them. Andy at Genos even threw in new pulley bolts at no charge. Can't say enough about Andy and Robert at Genos, their service has always been superb, and the fact that my office is only about 30 minutes from their warehouse is a plus.
I installed the damper, torqued the new pulley bolts to spec (40Nm, then 60 degrees). Found out during the install that its no longer possible to change the belt without removing the damper.
But, I digress. All seemed well for the first 3 or 4 days of driving. Then I noticed a change in the type and level of engine noise after warmup. Under light load between 1200-2000 rpm I could hear an intermittent rpm related knock, which would change to a very distinct rattle when lifting off the throttle. the knock would settle down when returning to idle. I listened to the front of the engine area with a stethoscope and had one of my employees run the engine up to about 2000 rpm & back down again. The noise was coming from the front of the crank damper area. After checking to ensure that nothing was touching the relucter ring or the pulley, I removed the pulley and belt (No rub marks on the pulley) and free spun all of the accessories to listen for noise or bearing roughness. None evident.
I called Andy at Genos and explained my problem. He put me in touch with Ivan at Fluidamper and Ivan agreed to ship another damper to me and I would return the original one to Andy at Genos. Great, I thought, must just be a bad one.
The replacement pulley arrived, I installed it, again with new pulley bolts (Thanks Andy) and set off again. Same thing occurred again after about 3-4 days (roughly 400-500 miles) of driving. Same noise, same conditions. It was intrusive enough that my wife said to me, "your truck sounds like a cacophony of crickets mixed in with a jamaican drum solo"..
At this point I was beginning to doubt that it could be the Fluidamper. Sooo, on Sunday, back went the stock, original damper. Since then, I'm back to blissful, normal Cummins music.
I talked to Andy about the second one, and he informed me that Ivan had called him, told him that they had run the first (returned) damper on their test bench and couldn't find anything wrong with it, so they were debiting Genos for it. I offered to pay Andy for both the first and second dampers because its not their problem, rather IMO, an issue with Fluidamper. Another thought occurred to me, if two new Fluidampers were creating this noise on my engine, maybe the motor is the problem? I took the truck to a buddy today that has a DRBIII tester and we ran a cylinder balance test. Everything checks out good. No uneven cylinders. I haven't contacted Fluidamper about the second one, and, frankly, not sure if its even worth doing so, given their response to Genos about the first one. I do know that I'm not impressed with the product, or their willingness to stand behind it.
I have the second one in my possesion, not sure what I'll do with it, maybe a boat anchor?

Hi, I am Andy Bishop from Geno's Garage.
We are sorry that you are having problems with your Fluidampr. We have sold dozens of the Fluidampers, with no problems. Overall, the customer reviews have been very positive. The Fluidamper company has been highly supportive of the industries that they serve, and very supportive of the companies that service the Dodge CTD owners. Fluidampr has fully supported us in the diagnosis of the problem, and replacement of the part. At this time, Ivan, at Fluidampr, is conducting further testing on the original part, which includes cutting the damper open to inspect it. Fluidamper is fully standing behind their product.
When the same complaint was made about the second damper, instead of another replacement, a refund was offered. We, also, fully stand behind the products that we carry. Please, never feel like a component purchased from is is no more than a boat anchor. We want you to be happy with the products you purchase from us to put on your truck. At this point, a full refund has been made on the part, and Fluidampr will not leave us holding the bag on that one, either.
Thank you,
Andy Bishop

There's definitely a difference. Call me crazy, but I think I hear the same "source" of that sound in both videos. In the Fluidampr video, it only seems amplified somehow... as if maybe the Fluidampr is merely acting as a diaphragm or drum to intensify an already existing sound coming from the crankshaft... or possibly the stock damper is, well, dampening the sound!I hesitated to post this video but I'm hopeful that one of our more experienced members (TC,Cerb or someone else. . ) may recognise this sound and be able to shed some light on the subject.
I think the slight metallic pinging sound with the Fluidampr is actually kinda cool. I like it!That's my noise, exactly! I've had it since last April when I installed my FD. It stays the same so I doubt anything is about to break.
It does seem to be in the background with the stock damper, just muffled.
These engines make a lot of funny noises. I'm interested in what it is but I'm not going to lose any sleep over it.
Try this,Block all wheels,set Parking brake. Step hard on the service Brake, place in D or R (Whatever is the safest Direction) load motor. . report back.
I think what is going on is the FD takes other noises out of the picture and there fore the "ambient" noise still being present appears to be louder. Larry
Kry226, good points but I dont think any of us have experiencing vibration issues with the FD. They work great in that regard!
fluidampr1: As I mentioned in my earlier post I am picking up a vib at idle. After making a 100 mile trip it seems to be vibrating constantly @ 1900 RPM. Arriving at my ranch I left the truck running while opening the gate when I noticed light metallic rattle coming from the front of the truck - down low. No sign on the dampener of any rubbing = just that on & off rattle.
