Well I had some free time yesterday so just out of curiosity I took my old flywheel...see it's good not to throw things away...down to the machine shop for a check. Sure enough it's not "0" balanced and the one we put on was. So now we're trying to come up with a fix. Here is the problem. First off it's an aluminum flywheel...no clues on mfg....motor was originally built around 1990.....the steel insert is in pretty bad shape...as in we don't think it could be ground enough to clean up and since we don't know the mfg. we can't order a new insert. One suggestion was order a new flywheel. Mfg. states that now they supply flywheel with an extra weight that bolts on so flywheel can be used either way.....sounds simple....but here's the kicker....from what we can tell by looking is that for some reason they used a "0" balance flywheel and just drilled out enough material along one edge to make it out of balance so to speak to compensate for the weight they needed....I'm talking about 10 or so 1" diameter holes drilled but not all the way through. What the machinist is checking into is if someone can take my flywheel that is on the car now and match it to the old one. If we can't do that it's buy a new one and hope it's close or the motor has to come down again to balance it all over.
But..........it's still fun
