2nd Gen Non-Engine/Transmission 2 piece harmonic balancer

[hpyman123]

Read the latest TDR and saw the issue with the balancer. Mine is definitely bulging out so I was wondering if anyone recommends a replacement source. Didn't look to difficult to get off as long as I don't have to use a puller. Anyone offer a little advice?

I traded my crankshaft dampner out for the Fluidampr. You don't need a puller, because it is held on by 4 bolts. Removing the bolts, while holding the dampner still is a trick. Same thing when trying to torque the 4 bolts going back together.



The Fluidampr seemed to tame the clutch noise on my truck & hopefully the benefits of the Fluidampr make help the longevity of the engine.

If you're willing to give it a try get the viscous 6. 7L crank damper, about $220 from Cummins. Only thing is you would have to shave a small amount off the fan pulley or get a 6. 7L fan pulley, which is another $40 or so.

I got my Fluidamper thru Summitt about 3 years ago since mine was walking and it really helped smooth things out nicely. I recommend it. As far as torquing the bolts / keeping the crank from turning . . . you have an auto trans so take the 3 screws that hold the converter inspection plate off and chuck a pair of vice grips on the flex plate hand turn the engine until the vice grips contact the bell-housing and you should be good to go. Crude but it works.
