1st thought is you need shims if the flywheel is hitting the starter. What is the year and model of the vehicle?
It sounds more like you are hitting the starter again after the engine is running.
Sounds like starter drive is not releasing--perhaps a bad starter solenoid
You re-engage the starter and you can damage the bendix, or the gear on the starter drive for the engine. It makes a grinding sound and will ruin the starter.
The noise is the teeth on the flywheel grinding on the teeth of the starter. Check to see if the starter is loose, this is the most common cause of that noise.
The starter could grind if the bendix is sticking
Certainly. Once the engine is running the starter is not needed.
If it is the starter that is grinding, the bushings are worn and the starter is "dragging" and not spinning fast enough to get the engine started. Replace the starter, chances are that the armature is damaged due to the dragging (grinding against the inside wall of the starter.
yes
ok ,you must be on about turning the key with the engine already running ,,once or twice you would get away wit ,as a rule you shouldn't have caused no long term damage
If the starter is whining while the engine is running at an idle you have a problem with the ignition switch or the starter solenoid is stuck. The starter should not be engaged while the engine is running unless you are holding the key over on the start position.
The starter solenoid is not disengaging once engine is started. Rebuild starter or replace with a new starter.
bad starter, or switch, or a short in the wiring. hope it helps. duboff
