6.2/6.5 Fluidampr?

[Fluidampr]

How about a front and rear pic of that bad boy, directly into the hub, for show'n'tell?

Maybe even include the oem hb?

We have a picture of the 6.2L / 6.5L Fluidampr on our website under the Durmax page: http://www.fluidampr.com/DURAMAX.htm.

You can also purchase any of our parts thru the distributors listed on our website: http://www.fluidampr.com/WHERETOBUY.htm. The performance diesel distributors are at the bottom.

Thanks,
Dan

What is the difference between the 800141 and the 800191?

800141 & 800191 is the same Fluidampr except 800191 comes with the spacer that goes behind the Fluidampr. This is for the older 6.2L engines that do not have the electronic reluctor wheel that the newer 6.2L & 6.5L engines. I believe the change took place in 1988, I am sure some of you can probably tell me if I am mistaken. With the older engines you need the spacer to lengthen the hub of the damper so the pulley's line up.

Robyn,
Yes our Fluidampr can be used with a steel crank however there is no need to drill the damper. When balancing an engine the crank is what should be drilled & balanced to the remaining rotating assembly. The damper should not be drilled whether it is stock or aftermarket. All Fluidampr components are drilled & balanced before they are assembled. Yes we are OEM for many CAT engines also, it is the same company, same technology.

If anyone has any other questions please let me know.

Thanks,
Dan

The first EFI 6.5 was released for the 1994 model year - '93-back did not require the reluctor.

The DSG Phazer timing gearset also has the separate reluctor for EFI - does the FD installation require replacement of that reluctor where the DSG set has been previously installed?

DSG reluctor is keyed for ~2deg advance - is the FD reluctor keyed for stock oem timing?

Any long-term EFI 6.5TD test results, say 50k-100kmi?

If we can assume the FD reduces the bad harmonics in these cast iron 6.5 cranks, the question I think some will ask is: "Will this end the crank failures we hear about?"

I suspect the failures we hear about will decrease, but not disappear.

Cracking failures of the 90's GM blocks could still be a contributor. Failed rubber isolated crank pulleys, defective dual-mass flywheels and loose torque converter bolts could still happen on rare occasions. Any of these pose a problem that couldn't be helped with an FD.

Another question: Could reducing crankshaft harmonics reduce the block cracking we hear about?

Now you know while I bought mine . It should take care of all that above if I am correct. If anything it will improve durability of the engine. Also how I look at it 500.00 over 5000.00-7000.00 and alot of agravation on getting the new parts just sucks . jmpo

The Fluidampr replacement does not require replacement of the reluctor wheel. If there is no reluctor wheel or anything to take its place you will need the spacer (p/n 800191). If a reluctor wheel is present or anything else to take its place you do not need the spacer (p/n 800141).

The Fluidampr is keyed so that the timing marks on the Fluidampr are the same as TDC on the stock damper.

Unfortuantely I do not have nay long term test results with that many miles. When I do I will be happy to post them.

If anyone else has any questions please let me know.
Thanks,

The reason I mentioned drilling the damper is that in years past I have seen units that were perfectly balanced then the damper was changed for one reason or another and then the assembly rerun and the new balancer was not the same.

The factory units have a big weight on the them and I have seen many that needed tweeking a tad to get them right.

Same goes for flex plates and flywheels, the production stuff varies a bunch and this can make for issues if the unit is replaced after an engine has been balanced.

Thanks for the good input

Glad to have you on board

I recently ran a balance test to check some of this out. We balanced a crank assembly to .06 oz-in per plane using a new damper and new flex plate. I had two other used dampers and one other new damper that we then swapped onto the assembly one at a time and checked the balance. One of the used dampers resulted in .06 oz-in per plane...no change. The other used and other new damper each produced .05 oz-in per plane...an improvement of .01 oz-in over the original balance.

The factory dampers don't seem to have much variance in them, from what I have seen.
