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.
At the back end of the engine is a large ring gear connected to the engine crankshaft. If there is a starter (some engines do not have starters) it will be mounted in the engine such that the bendix gear of the starter can engage the ring gear and spin the crankshaft. It's called a bendix because it jumps out to engage the ring gear (while the starter motor is running) and retracts off of the ring gear once the engine is running (starter motor no longer running). It is typically access from under the car. If you must replace it, let the engine cool off first. Otherwise the starter will be just as hot as the engine is.
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.
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
The starter solenoid is not disengaging once engine is started. Rebuild starter or replace with a new starter.
When starting an engine the starter motor turns the crank shaft via the fly wheel at a set speed. Once the engine is running the speed of the flywheel increases above the speed of the starter motor. To stop the starter motor from being damaged once the engine is running a clutch mechanism is used to stop the flywheel turning/ spinning the starter motor mechanism too fast or 'Overrunning'.
bad starter, or switch, or a short in the wiring. hope it helps. duboff
Starter misaligned? Starter engaged with engine running? Metal fatigue?
Probably a stuck solenoid.
It cranks the engine over in order for it to start running.
The 1991 Ford Explorer should have a separate starter relay that sends power to the starter. It sounds like the relay has stuck and is sending power to the starter even after the vehicle is running.
Could either be a bad starter drive or a bad tooth on the ring gear/flywheel Try turning the engine manually (large socket on crankshaft) and see if it starts without grinding. If so, probably a bad tooth. If no change probably a bad starter drive
Not supposed to. Problem is most likely not releasing quickly enough once engine does start, usually bad starter & or solenoid or you need some shims.
As long as the engine is not running, you can wipe the starter casing down of any oil spilled on it. Since the battery delivers a substantial voltage to the starter which is required to crank the engine; you wouldn't want to accidentally touch the terminals on the starter when it was turning over.
The grinding noise you hear is probably coming from your starter. When the bushings wear out, the armature "drops" against the casing, making it difficult to spin without "grinding" on it. Starters can be rebuilt if you are mechanically inclined - you can buy a "starter overhaul" kit at almost any auto parts store. Before you buy a kit, remove the starter and inspect it - it might be too far gone from the grinding to overhaul. If that's the case, you will need to buy a new or rebuilt starter.
Two possibles: It needs to be shimmed. Chances are if it is a replacement starter it needs to be shimmed. you can buy shims at almost any parts store, they go between the starter and its mounting point on the block. usually one will be sufficient. also possible you have burrs on the flywheel or starter gear that are hanging it up, should be able to tell that when you pull it to add the shim. I recently had a starter grinding problem with my boat which has a Chevy 305 engine. You could lose a lot of time trying to find the correct shim thickness, not to mention you have the possibility of breaking a bolt off in the engine. I fixed my problem by having the starter bolts just loose enough to move the starter with my hands while I had someone bump the ignition switch. I had to move the nose of the starter down and it corrected the grinding.
That is a broken/worn teeth on the flywheel or on the starter pininon gear. That is why you hear a grinding noise. It's the starter turning without being able to engage.From what you describe I would suspect that the starter is not fully engaging. I'm assuming that the grinding noise you hear when you try to engage the starter is INSTEAD of the engine cranking. If I assumed wrong, ignore the following:Pull the starter, check the flywheel for excessively worn areas. Most of the time the flywheel is ok, it's just the starter. If you feel comfortable working on the starter, just get a new bendix and clean up the rest of it. Any time you disassemble a starter you should replace the bushings and brushes. Never remove the starter with the battery still connected. Remove the negative terminal from the battery before you attempt to remove the starter.
The grinding noise you hear may be due to worn bushings on the starter. When the bushings wear, the armature will "drop" and grind against the inner part of the starter, causing it to rotate slowly and not spin fast enough to start the engine. Remove the starter and have it checked out at your local AutoZone or similar auto parts store. If the bushings are worn, it is likely that the armature and internal wall of the starter may be also be damaged and the whole starter will have to be replaced.
