Engine/Transmission (1998.5 - 2002) Dorman harmonic damper

[TPringle]

Has anybody used or had any experiance with the stock replacement harmonic damper from the auto parts store for a shade over $100? I'd like to hear from you either way.

How about trying a 6. 7 viscous damper and fan pulley? Somebody needs to be a guinea pig for testing that. :-laf

I have the doorman damper on my truck, this summer my old one started seperating, and I did not have the dough to go with fluid-damper... been fine so far.

Ok, I got the Dorman damper (right before Geno's had their OEM for $180!), and I am trying to decide if I should use it or return it. It doesnt look like it is pressed together quite right. The rubber isnt even around the inside and outside. Here are a couple of pics. Take a look and see what you think.

Below is the original. Thought I'd throw this one in for laughs!

Dorman is usually cheaper for a reason. You get what you pay for.

If the Geno's OEM is $180 then converting to the far superior Fluidampr-style 6. 7 damper for $276 would make a lot of sense.



Part numbers, order from Cummins

Damper is 4933224 $224. 04

Fan Pulley 4930580 $47. 07

Bolts not sure about PN or could probably reuse originals

Yea, you are right - I got what I paid for. Junk. It will be on its way back to where it came from! I learned! (Wow, does that sound humble???) I already ordered and received the damper from Geno's. Was a little more than the Dorman, but I'm not going to worry about a broken crank now! It IS made in the USA! What a difference.



I'd have given the fluidamper a chance, but I was a day late and a dollar (or hundred ) short. I didnt catch if anyone has tried the 6. 7 damper on the 24v engine or not.

Oh, I GOT to throw this one in. This is MY barring tool. :-laf Primitive Pete here. Pleese dont shoot me! There was some discussion about the torque of the bolts. I found 92 ft lb in a service manual, so thats what I cranked 'er down to.
