Re: Can I replace the flywheel myself?
Es you can do it yourself...you have to back the transmission off so you can get to it and then unbolt it from the torque converter and put the new one in and bolt the transmission back in place. about a 4 hour job if you know how to to work on vehicles. a bit longer if you dont but you can do it

the ring gear on the fly wheel may have damaged teeth or not have the right gear teeth count to be compatible . Pinion teeth have to match the ring gear teeth or they have trouble meshing and that makes it hard to turn over. If the ring gear teeth have been damaged then the gear box will have to come out to get the fly wheel / flex plate off. If it is auto then it is a simple matter of replacing the flex plate . But if manual the ring gear is removed from the flywheel and a new one fitted. Most accredited service shops can do this operation. count the number of teeth on the ring gear and the number on the starter pinion and take the figures to an auto electrician and he will know it they are right.
It could be either the flywheel or the starter. If it's grinding, don't try it again until you've removed and examined the starter and flywheel. If the starter solenoid isn't fully engaging the bendix, it will cause the gear to grind; replace or rebuild the starter if that's the case. But you should examine the flywheel to see if it is seriously damaged from the problems you've had. Put a mark on the flywheel using a magic marker, then examine the flywheel as you slowly turn the engine by hand. (make certain that the ignition is off when you do that, you don't want anything bad to happen to your hand.) The mark on the flywheel will indicate when you've been able to examine the all of the teeth on the starter ring.
I have also suffered this problem. The starter motor has a component called BENDEX. It is the part that pushes the starting pinion forward and backward so that it engages with the flywheel when you want to start. And when you release the starter, it retracts the pinion and it disengages from the flywheel. As the flywheel is much larger than the pinion, if it does not disengage the starter motor will get burnt as it would be subjected to a very high RPM by the flywheel. So, get the bendex repaired. If it can not be repaired for some reason then replace with a new one.
Does it sound like a screeching or grinding sound? If so - it could be the starter is going out - there is a part called the bendix spring that is probably not engaging completely and it will cause the teeth of the starter to not fully engage the flywheel - which makes an awful sound.
It looks like you have an issue with the starter not engaging the flywheel correctly. Does it make a BrrrrRRRRRRRRRRP noise? Best advice: Replace the starter. Do not get it rebuilt. If you replace the starter ASAP, you may be OK. If not, you are going to have to have the transmission pulled, and you will have to replace the flywheel; that is what is being damaged by the bad starter drive. This is, unfortunately, a common issue.
Thanks for choosing FixYa for advice!
A FixYa rating (4 blue diamonds) would be most appreciated, this is how we are scored. Thanks in advance.
no, it shouldnt have any looseness to it and dual mass flywheels are VERY expensive to replace, BUT yes it can be converted to a solid flywheel, check out autozone.com part number MU1989 or advanceautoparts.com part number 798, that should get you on the right path to curing your problems, i welded the two independantly turning discs of my dual mass flywheel together but i wouldnt recommend anyone doing that without the proper equipment to do so (i.e. precision lathes, cast iron welding rods, etc)
Wow it sounds like that they are not shiming the starter. On general motors products a new starter has to be shimmed, so that it lines up correctly with the flywheel. This is what is causing the flywheel/starter bolts to break and the noise you are hearing. Its not a hard process, just time consuming probably why it has not been done.
Sorry. Good luck! Dont forget to rate. Thanks, James
