broken flywheel

I have a 01 2500hd 6.0 automatic 4x4. The flywheel keeps breaking. Had trans rebuilt lastyear. Aftermarket flywheel broke in 2 months. Replaced with Chevy flywheel and new converter. This lasted 10 months. Noone at trans shop or dealerhas any ideas. Thanks.

RE: broken flywheel

define breaking. teeth sheering? crack in wheel?
Was the aftermarket one lightened? Some hi-perf applications will lighten the flywheel for weight. And some will use stock or HD for fuel economy (keep rotational inertia going). Perhapd you simply need a heavy duty one.

RE: broken flywheel

sounds like something is not aligning right and putting it into a bind. or the flywheel bolts maybe over tightened.

RE: broken flywheel

Flywheel isbreaking around where it is bolted to engine. Flywheel is stock for a HD. Bolts are to specified torque.

RE: broken flywheel

Its uncommon but on occasion the thrust washer on the crankshaft will be worn and allow the crank to move back and forth. Its kind of like taking a wire and bending it back and forth eventually it will break.

RE: broken flywheel

sounds like something is binding up then. maybe bad trans mount or motor mount. the bell housing may not have been aligned right when bolting back up to the trans after ur rebuild. do u have ne trans fluid leaking from the from pump area??
