Group Purchase on Fluidampr Harmonic Balancers

[RoadGoesOnForever]

Here is the email I just got from them:



Hi Tyler,







We are aware of this issue, we tried to contact all our distributors to put a hold on that Fluidampr and somehow the one you purchased must have slipped through. We are working on a correction for the tach sensor; we will either decrease the diameter of the damper or design an offset bracket to include with the damper to move the tach sensor out of the way. I am hoping to have this problem resolved in 2-3 weeks. When we tested this damper on the dyno last September I have learned that they did not use the tach sensor during the test, they just moved it out of the way without making a note of the interference problem. I apologize for any inconvenience this has caused, If you would like to hold onto it for now I will notify you as soon as we resolve this problem, if not you can send it back for no charge and if we need to modify the damper you have we will exchange your damper for a new one. If you would like to send it back please let me know so I can give you an RGA # to return the damper.



Again I apologize for the inconvenience.



Thanks.







Dan Oddy

Hopefully this ends on a good note.

Thanks for the update guys.

So, does everybody that has one of these think they are worth it? Are they mainly beneficial for the 24v engines or the 12v engines as well? Until reading about them on this site, I haven't read anywhere about the harmonic balancers coming apart. I have a 12v modified, running 450 to 500 hp... ... . which one would I need? I realize the group buy is over.

mine arrived yesterday---also is the torque spec's right 30 lbs plus 60* vs the stock setting of 92lbs--this is for a '99 24 v---sure seems like a huge discrepancy--chris

Chris,



Use the factory torque.....

These things are mainly for those who want that extra smoothness capabilty. For some it makes a notable difference, it all depends on your set up. I didn't notice any difference really but then I didn't expect to. I'm thinking there is a little less vibration going on inside the crank but then it's probably more in my head than in the crank shaft. Bottom line is, it's a mod you could do without.

The more beefed up your truck is the more reason to get one I think. The older the stock dampers though, the less effective they are.

I bought mine for peace of mind, as well as noise reduction when I go to a dual disc clutch eventually. All of the high HP engines Cat makes use a damper similar to this, so I know it makes a difference in the torsionals experienced by the crankshaft.

so 92 ft lbs it is--thanks Doug---chris

Here my latest e-mail:



Hi Tyler,







I am waiting on the owner to bring in a truck so we can fabricate a bracket for the tach sensor. Unfortunately he is out of town until next week so it might be a week or two before I have a bracket to send to you. I apologize for your inconvenience and I will keep you posted as soon as we began making a bracket.



Thank you for you patience.



I can't believe that a company that size can't find a 12 valve any sooner to fix this problem

Or the fact it does not fit the first 9. 5 years the Cummins was available.

I'm very interested in this, but I'll wait until problem is solved.

Doug- Just talked to Haisleys the other day and said that mine had arrived a few days earilier. Thanks for all the help on figureing if this would work. For my application (GM 12 valve conversion) I was able to use the larger ballancer and I don't have to worry about the sensor because the GM alternator runs my tach!



The reason I bought mine was because #1 my engine is being totally built out of the truck... why not put it on for piece of mind



#2 is that in my pulling class I either have to run an SFI ballancer or run a 1/4" thick steel loop around the ballancer which I didn't want to do in the first place!

Very dissapointed w/ Fluidampr already and I have not used their damper yet. EDIT: I tried to use their damper but it was a waste of time. I am not blaming Doug.

ok--I must be a moron or something--my big service manual says remove fan and belt--so I did---then is says remove 4 bolts---nothing more, beyond check for this and that--how in the 'ell do you keep the engine from rotating when trying to loosen the bolts and then again when you torque 'em down--I tried to wedge a crowbar back at the flexplate, but it won't fit right and it probably wouldn't stay there if it did---I could wedge a bar at the front, but that would bend the pulley possibly or the front of the oil pan--so do I need another guy to hold a big screwdriver at the flexplate or am I missing something totally easy here---and then will the damper just slide off or do I need a pulley to pull it off----1999 24v---frustrated ----chris

Chris,

IF you have a snap-on barring tool or the equivalent install that into the trans case with a ratchet to brake the engine from moving (you might not even need the ratchet there, can't remember) and go for it.



The damper on these trucks will fall off without bolts so be careful or you might need a new face.

 

[csutton7]

jwilliams3---I was afraid that would be the case and nope don't have one of those--guess I'll just slap the fan and belt back on and wait until I have some help--thanks for getting back so soon with the info--chris

 

[BigBadDodge]

Chris, I have one you can use.

BBD--thanks--will let you know if I get up that way... ... chris

Installed Fluid Amp Last Night

I just installed my FA last night, have not started the engine yet net to recheck the bolt torques. The 92 lb-ft can be held if you leave the belt on before you remove the plate and install the belt before you tighten. As a matter of fact the motor seems to rotate right at 92 lb-ft so you really don't need a torque wrench but you should to make sure. I did not remove the fan or the shroud but the back of my hands look like I have been dragging them on concrete. You will need a small mirror and a bright light to line the 4 holes. It is a ***** getting the bolts in the new pulley since the flange is deeper than the OEM flange; hard to see and feel. But with a little time and patience you can do it without removing the fan. THe fan is not the problem it is the damn fan shroud and the sharp plastic edges. The fluid amp came with an alignment hole but my 2001 does not have an alignment pin so it must be for other applications. Like I said I have not run the engine yet so will report back. THe FA is pretty impressive piece of iron as compared the factory unit.

 

[csutton7]

thanks for that update--I was pondering leaving the belt on and attacking it again--will remove the fan though as that's pretty easy--now if it will stop raining--chris

There is what you need to keep the engine from turning over while torquing the damper.

Also a must for valve lash jobs.
