Re: Fy wheel Ring gear replacement
Remove the transmission from the motor. unbolt the clutch if it's a standard... remove the flywheel bolts ... pull it off and reinstall the replacement... reinstall the clutch and transmission and you are done. two things to do first are to unhook the battery... and remove the starter.

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.
There is no way the ring gear will hit the starter pinion unless the fly wheel bolts on the crank shaft or loose allowing the flywheel to run out of true. If you have had clutch/ rear seal work done lately the fly wheel will only fit in one position and if that was ignored at some time then the fly wheel will run out and touch the starter pinion.. I would also check the adjustment on the starter pinion as it has to be set by the lever pivot to a correct distance or it will touch the teeth of the ring gear
Most ring gears are only shrunk fitted on the fly wheels. REmoval is by simply driving a good cold chisel in between the teeth and cracking the ring . Replacement is by heating the ringear evenly and placing onto the flywheel and letting it cool down. Ensure that any timing marks on the ring gear are in exactly the same place as the one removed. THis heating process may not work if there are sensors in the ring gear for cpu operation Check with service dealer for further info.
You are refering to the teeth part known as the ring gear. It usually wears in 2 places ad in te old days we used to heat the ring up to release from flywheel and turn it 90 Deg and let cool and refit. Just as easy to get new flywheel these days
You need to make sure that the starter is positioned right first, sometimes they need to be shimmed to change the position. In some cases though this can mean a warped a fly wheel. Make sure none of the teeth the fly wheel are missing. I had one missing once and anytime it hit that spot i had to move it which isnt easy on an automatic.
IF the BENDIX is being accentuated as you state, then the shear pin on the gear which engages with the Ring gear on the fly wheel is sheared/broken and needs replacement, IF this is the case, most likely the gear teeth of either or both are in bad shape for your sake I hope it is the gear teeth NOT the Ring Gear teeth...
it can do the pinion may be worn, take off the motor and see! do it now beause it might be the ring gear, you see if you ahve a bad pinion then it will dammage the fing gear! if the ring gear is dammaged... you can replace starter,, It may seem fine, but the dammaged ring will grind up the new starter's pinnion, once the ring gear is dammaged then it is gear box out! so look now to avoid more lenghty and expensive repairs!! Have a nice DAy........Bruce.
Yes it could be wear on the ring gear.To check move the car slightly when in gear and try starting again. or remove the starter and check if any teeth are missing on the ring gear. (the ring gear is a large cog wheel around the outside of the fly wheel). It is still most likely to be the starter. Although it seems ok the sylanoid may be to weak to throw the cog wheel into the ring gear
You need to pull the tranny out. Then the flywheel needs to be unbolted from the engine. if it's an automatic, purchase a new flywheel, if its a clutch, you can have a new ring gear pressed on to the flywheel...
