the starter bendix is bad or the flywheel it self has some teeth missing
The Starter Bendix drive is not close enough to the flywheel. Reinstall the starter and check to see if there are shims that can be removed to place it closer.
if the starter is spinning but not engaging then the bendix (starter teeth) is not moving out to grab the flywheel teeth or the flywheel has some broken teeth. The starter needs to be removed to see what the issue is.
If the starter spins but won't engage, then the Bendix is not engaging the flywheel. Remove the starter and test to see if the Bendix thrusts out, and check to see that the flywheel does not have chipped teeth.
Usually, the engine flywheel. A solenoid in the starter moves the starter pinion shaft forward (or backward depending on how it is mounted to the engine) to engage the outside edge of the flywheel (which has teeth to match the pinion gear).
A bad flywheel can definitely cause the engine not to turn over. The flywheel has teeth. If the teeth are chipped or broken, then the starter can not engage to spin the engine over.
Yep, a starter can whine worse than a little kid.If the "bendix" doesn't kick the gear out to fully engage into the flywheel teeth - and even worse: if the teeth on the flywheel are worn down/away.A physical inspection of the starter and flywheel gear-teeth will be a good guide.
Some vehicles require "shims" to be installed when a starter is replaced so the Bendix drive will engage the pressure plate teeth. If the starter is too far away from the teeth on the pressure plate, the vehicle will fail to turn over.
Assumeing it's the same starter, the bendix(the gear on the end of the starter that engages the flywheel)could be bad, and or the starter it self could be bad. sounds like number of teeth on new flywheel does not match number of teeth on starter. find out from mechanic that installed new fly wheel, how many teeth on flywheel if he doesnt know, a ford dealer can tell you from the part number on your receit. then ask how many teeth should be on starter to match fly wheel pull starter and count teeth
Could be the starter drive is not engaging or perhaps you're using the wrong holes for your flywheel. If you have a 153 tooth ring and have the starter in the 168 tooth position, the gears would not mesh. Did it ever start? if it did ,most likely the starter drive is broken, or the pinion ,or flywheel are stripped of their teeth. Bendix is broken, Starter too far from ring gear, broken bendix throwout fork.
2 things that come to mind: # The teeth on the gear are worn down - that would prevent them from engaging with the teeth on the flywheel and turning the engine over # The starter gear is not being pushed out far enough to completely engage the flywheel Either way, it's likely the starter is coming out for repair or replacement
Starter Drag is when the teeth on the starter that spin the flywheel drag. It could break teeth off of starter possibly have to replace/ rebuild starter.
The starter bendix is not mating with the ring gear on the flywheel. The soleonoid on the starter motor may be faulty or the teeth of the flywheel or the bendix may have stripped. A bench test of the starter motor would be advised.
You may need to shim the starter. When you turn the key the gear from the starter is slamming into the teeth on the flywheel. Did you get any shims with the new starter? If not you may need to buy some. You just want to shim it out just enough where the teeth from the starter and imbedded into the teeth on the flywheel. Not too much and not too little otherwise you will chip or break a tooth off. You are trying for a good mesh of teeth to teeth.
