I am doing a clutch job and I was wondering if I should get the flywheel balanced since they will be taking upto(?) .040 off the flywheel.

 

I wouldn't think you would have to have it rebalanced.

 

I would not think so either but theres always some kind of VooDoo black magic going on in engine building that you can miss.

 

You shouldnt have to with only that much being taken off. Why not ask the machine shop doing the work if they reccomend it?

 

I barely feel comfertable letting anyone touch my shtuff, but I have no choice cause I do not have the machinery. I have this bad incling that that are gonna do a .100 grind just to be lazy and say "oh, it needed that" when they just dont want to be prissy with it and have to set the machine 3 or 4 times to take off juuuuuuust enough to get the job done. Too bad I dont know which shop is good or not, yet.

Who knows, they might even say I need to rebalance the whole engine, lol.

 

you cant take off that much like that when surfacing a flywheel. youd be jamming the machine into the flywheel. basically the machine spins around and the grinding wheel spins really fast against it. you slowly lower or raise the grinding wheel to remove the metal. thell do it slowly to remove the high spots then keep doing it til the low spots are gone. after that your done. so if you only need .040 removed they would be wasting their time going to .100.

Except for the neutrally balanced harmonic damper, the LT1 is externally balanced by the flywheel/flexplate. There should be a weight on it. If an even amount is taken off of the flywheel surface it shouldn't change anything.

 

Yea, I know that. I was not sure how much they take off at a time with a grinding stone. I was just using that as an extremely exagerated example. Using your example, .010 + .010 = .020 when only .012 needed to come off.



I didnt see "weight" per say, but I did see a lot of drillings in one paticular area. Not sure if there was a weight pad at that spot or not but I guess if the engine is balanced WITH the flywheel, then it does not really matter if I want to balance it or not.

Then again, if I want to go auto, I would need to return the flywheel, get a balance readout and then apply that to the new flexplate for a proper perfect balance, ehy??
