flywheel visual inspection
Hey guys, I posted last week about single mass flywheels, but yesterday I yanked the tranny and flywheel off my donor truck and I was wondering what to look for on the dual mass to know if it's good or bad? The donor truck was burned, so I couldn't run it to check for symptoms that way. I just know mine is bad and this one may be good. And it's free. Any ideas. Maybe next year I'll do the single mass thing. No $$$$ right now.

Check all of the springs for looseness, cracks, misalignment, check the center bearing for seperation and misalignment. The best bet is to take it to a machine shop that turns flywheels and let them take a look at it for you. Most places cannot resurface the DMF's.

Mine is destroyed. One of the springs is hanging there, doing nothing. When Ideling the truck with shake violently (half the time) until I get over 1000 rpms. Sometimes when Ideling I can rev the engine a couple times and it'll idle right.
So, can I cut that spring off and it'll run right?
Thanks.

Hey phrase "Mine is destroyed". No you cannot just cut that spring off. It will get progressively worse, and the vibration is not good for the tranny or engine. I have seen two that were driven so long after the DMF started doing bad things that they had bad cracks in the transmission housings. Very costly repair. Replace it with a SMF.
