Fly wheel timing position - Cars & Trucks

There are teeth on the fly wheel and you may have broken one or more teeth. You may have to replace the fly wheel. When you turn the fly wheel by hand you make the good teeth so the starter will work.

on the fly wheel. the bolt holes on one side will show where the fly wheel washers sat. if the tranny is out the way you can test fit it for both sides and see witch side lines up the best. and if there is factory paint markings on the fly wheel that is the side that needs to face the tranny.

IF the magnets are fixed in position with not allowance for adjustment then the timing should be the same as before. The problem may be that if they have hit on the coil as they come out then it may have moved and that will alter slightly the timing point . Basically I would expect it to start as before.

replace the starter and the flywheel-the bad starter has not engaged the teeth on the flywheel fully and has ground some teeth off so you'll fit that space every once in a while-cheers Denny

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

You need to have your flywheel: replaced.Your starter motor engages against the fly wheel at the back of the motor. Every time your motor stops it tends to be in the same few positions (just the way things work) so there is more stress on some parts of your fly wheel than others. Because of this the teeth wear out on the fly wheel which means the starter can correctly engage on the fly wheel which is the grinding noise.

Does it turn over as it grinds or does it just gring?

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.

to be honest it not as easy as it sounds to line them both up,,,,you may need to use a locking stud to do this,, and i have seen engines that just wont line up even to half a tooth out,,, but they run just fine anyhow, its all down to just how good the pullys were cut and marked

 you need a shim, if its screaming your clearance is to great. Are you positive its the right starter?
