Fluidampr

[longbedder]

Has anyone here lightened up up their bank account and installed a Fluidampr on their 6.2?

I have a alot of belt slap, and it seems like one of those may smooth things out a bit (as well as contributing to the life of the crank). It also wouldn't wear out like the stock rubber setup.

For those that are unaware, the Fluidampr part number is 800191. They've got em for $420 at Summit.

No. They have a good reputation through. Cheaper than a broken crank/block.

not on a 6.2, but..

I put one on the 331 in my 69 Camaro.. I love it..no more timing tape to screw with. definitely worth the bucks in my book, just for the ease of use..

Okay, I'm not an engine builder by far and still pretty new to diesels.

What part is this Fluidampr replacing? All I know is Big Ugly rattles like ever other 6.2L I've ever been in.

It replaces the harmonic damper on the crankshaft.

The stock damper is basically a circular weight connected to the crankshaft pulley via a rubber spacer. The intended purpose is to dampen the torsional vibration every time a cylinder fires. Diesels have an especially nasty vibration mode by nature (sometimes called "diesel spike") that is hard on parts (the crank and the block at the bearings). The stock damper is not the greatest, and is known to wear out. If it does wear out (the rubber hardens or crumbles) the part becomes ineffective. I have seen no hard proof, but damper failure is believed to be the chief cause of crank and block main web breakage in 6.2 diesels.

Fluidampr uses a circular weight also, but it is much larger, and is suspended in what amounts to silicone goo. This goo won't wear out, and the system is sealed. They also say (and I'd tend to believe them, based on modulus of rubber vs. goo) that it also performs better than the stock setup.

Gotcha, thanks.

Just got added to the "someday" list.

i recently replaced my crankshaft pully. I was going to put a fluidampr on there, but my stock damper was in good shape and the wife did not seem happy with the price tag on the fluidampr. She gave me the turbo or damper look. I quickly said turbo!
