Hi all,

I installed a new Mcleod clutch and flywheel in my 02 SS with the M6 and after the install it has vibration I can feel in the seat across all RPM.
I did get the flywheel and pressure plate balanced before hand however question how good of a good they did as the print out they provided shows its balanced about 13 grams out from neutral.

My question is: Is this variance out of spec from what GM would want or what is generally acceptable for our engines? I called Mcleod and they said if they balance its usually within .5 gram so seems this machine shop did a very poor job.

Below is the print out of the balance and i convert oz inch to grams as that seems to be what people reference

Thanks all

 

Anyone.... somebody must know.

 

I don't know what a good number is for tolerance on that, but I do know that it is sad that they gave you a spec sheet showing that they let it out the door at well over double the imbalance that the bottom of their own page shows for a target spec.
