    Default Testing fluid dampers

    JK,
    Fluid dampers can be checked to ensure that they are working as they should.
    It requires a special piece of equipment, looks like an electronic set of scales. The damper unit is sat face down on the tester, a switch is pressed which activates the tester which puts a vibration at a set frequency into the damper, the test unit then tells you if the damper is operating by the way the damper has controlled the vibration.

    We used to have fluid dampers tested this way when rebuilding engines fitted with fluid dampers to ensure we didn't get any comebacks (broken crankshafts) due to faulty dampers.
    The only dampers that tested faulty generally had external damage (dings and dents) which usually restricted the free movement of the internal damper ring.

    FD says you shouldn't drill into the damper to attach other accessories either....

    I got mine installed yesterday, really smoothed out the engine. I'm very happy with it.

    I wanted to post an FYI though. We called and ordered it and told them the make and model of my burb, they sent the wrong one anyway. It seems their sales force are not up to speed on the technical issues of what you need. Regardless of what the salesman or catalog says if you have a mechanical engine you will need the spacer. The snout is shorter to fit the 6.5's with the engine speed sensor, so no engine speed sensor equals spacer.

    Hope this helps.

    Default Fluid Damper

    This thread is timely for me. My sweet bumper mounted FSD cooler set up I noticed vibrating appreciably at idle on my Tahoe. I checked the Sub at idle as a comparator and it was solid as a rock at idle; no vibration whatsoever. The vibration is so pronounced on the FSD cooler on the Tahoe I worry about the FSD's longevity: I have applied a temporary fix of 'lashing' the farthest end of the cooler away from it's mounting to the bumper with some line and a spring to the available holes at the bottom of the bumper, we'll see the results.
    I was shocked at the difference of vibration on the Tahoe at idle vs the Sub. When throttle is brought on on the Tahoe it smooths out fabulously throughout the RPM's.
    Question: could my rubber damper on the Tahoe be headed south?
    I may be in the market for this fluid damper sooner than I had anticipated.
    Also, how tough of a job is the replacement of the OEM fluid damper, looks like an old harmonic balancer to me and would be a similar job.
    Thanks.

    Replacement isn't too bad. A good time to take care of other wear items due while you're there. Water pump, timing set, front seal, radiator (clean). The OEM balancer is an "old harmonic balancer", rubber and steel. The Fluid Damper is an aftermarket upgrade.

    I ordered a fluid damper for my 6.2 F150 project from Summit on Nov 5, they said it would ship on the 8th. Then I received a notice that it was unavailable until the 20th. Now I received another notice that it is backordered until the 29th! Wonder whats up????????

    Summit does not stock them. Once you place an order, They order one directly from Fluidampr/Vibratec. Once Summit receives it, it then ships out to you.

    If you look at the item on their website, the availability will always be about a week later. That's the timeframe assumed before Summit receives it.

    As Dan has stated, they should open their eyes to the Diesel Performance Aftermarket. Maybe they have, but who remembers the 6.5 crowd.

    Default Who remembers the 6.5?

    Right now, there is a wider variety of products and more vendors for the 6.5 than at any time in its history. The diesel phenomenon is pulling the 6.5 along with it.

    Fluidamper was at the SEMA show a few weeks ago. Dan was there and they actually had a 6.2/6.5 unit at their booth. Dan said they had them in stock.

    Looking at the Fluidampr website for the various 6.2/6.5/Duramax models:
    http://www.fluidampr.com/DURAMAX.htm

    This conflicts with what is on the Diesel Page article website:
    http://www.thedieselpage.com/features/fluidampr.htm

    Fluidampr website lists #800191 for '82 to '87 6.2 engines and #800141 for '88 to 2000 6.2/6.5 engines.

    TDP article lists the #800191 for 6.2/6.5 mechanical injection pump engines and includes a spacer to make up for the reluctor wheel while the #800141 is for the electronic injection pump 6.5 models.

    Is this correct?

    Is it also correct that the only difference between the two part numbers is the inclusion of the spacer in the #800191 kit?

    The FD photographed for the article was pn-800141, which is intended for the EFI 6.5, and is described on the invoice as "8" 6.5 GM Diesel, 92-02".

    As far as I know, the spacer is the only difference between the two part numbers.

    Where this can be tedious is when a new 6.5 has been installed in an earlier truck. So, if your engine has a CKP (Crankshaft Position Sensor) and reluctor wheel ahead of the crankshaft sprocket, you'll need pn-800141. If your 6.2/6.5 does not have a CKP, you'll need pn-800191.

    That's right Jim, p/n 800141 is for the electronic injector pump engines using the reluctor wheel. P/n 800191 is for the 6.2/6.5 mechanical injector pump engines. Both p/n's are the same damper, in fact if you order 800191 your Fluidampr may be stamped as 800141 (sorry for the confusion). When we box up an 800191 we use a 800141 damper & throw in the spacer to replace the relcutor wheel for the mechanical injector pump engines.

    I am not sure why Summit does not stock these parts & then they give you a ship date that is so far off. We are quite pleased the way the new 6.2/6.5 Fluidampr has been selling in the last few months.

    This is why I usually send diesel customers to performance diesel shops & not the large warehouses. It just makes more sense to send diesel customers to specific diesel performance shops, especially the ones that keep them in stock so you can recieve your parts quicker than having to wait a couple weeks.

    Let me know if anyone has any questions.
    Thanks,

    Thanks for the clarification - was pretty sure I understood but wanted to make sure. Might want to clean up the Fluidampr website a bit to avoid the confusion with the years there...

    Couldn't find the Fluidampr available through any of TDP advertisers. Not in a real hurry for it, so will probably go through Summit. Maybe if enough people are ordering them they'll start stocking them.

    I have been meaning to clarify that better on the website, I'll try to take care of that this week before everyone is recovering from Turkey overdose. Of course its hard enough with half the plant gone since shotgun season opened!

    The only TDP advertiser that I see that carries our Fluidampr line is Diesel Performance Parts, they have been a distributor for us for about a year now.

    Thanks,

    I couldn't get to where I could actually order anything off the DPP website - trying to select any item with their "search" only provided: We're sorry. We could not locate any items in our database with the search criteria you entered.

    I tried several items other than the Fluidampr with the same results.

    trbankii,

    We don't have the 6.2/6.5 Fluidampr on our site yet, just the 6.6 Duramax. Rest assured if you can call us at 866-455-7788 we can get you the part you're after. In fact we have sold a lot more of the 6.2/6.5 Fluidampr's than I ever thought we would.

    Mark @ DPPI
