My car won't turn over and sounds like a soft power drill when I try?
Topic: Case starter drive
June 17, 2019 / By Dalinda Question:
My lights and radio all still turn on when I put my keys in. So I'm assuming the battery is fine, however when I try turning it over all I get is the soft sound of a power drill or dentists drill. I tried giving a couple pushes on the ignition and it doesn't do anything. No sound but the drill. It sounds like a belt is spinning and not connecting to what it needs to. I had no trouble with this at all previously.

Although it would be preferable if I could here the sound, it's almost certain (90-something-%) from your description that your starter drive gear has gone out. This part has a one way clutch in it, so that when your engine starts, it doesn't drive the starter to go faster than it should/does on it's own, during that moment before you let off the key. It's really not at all uncommon for this clutch to go out, and it makes a sound that most would describe as a very loud moan. The other only real possibility is that though your solenoid is working (if the starter motor is spinning, it has to be), the linkage between the solenoid and the starter drive gear could be broken, but it's pretty rare for that to happen.
Now, if you get a whole starter, with or without the solenoid, it will come with the drive gear as part of it. But, if you're handy enough to take the starter out of the car yourself, it's pretty easy to change just that part, and it only costs as little as $8, for my Chevy 350 for example. Most other types will cost a little more, but not much. Compare that to the cost of a whole starter, and it could add up to a fair amount of money.
Anyway, here's what the one for my Chevy looks like. Most others are pretty similar.
That first part to the left of the gear is the clutch that goes out. The part all the way left is the groove the lever from the solenoid fits in, to push the whole thing towards your flywheel/flexplate.
This is how it goes together inside your starter case. All you have to do is remove the snout (the aluminum part in the 2nd link), remove the retainer, and slide it off. Slide the new one on, put the new retainer on, and fasten the snout back on.

Originally Answered: I'm going to buy a drill bit, so a high speed steel twist dril bit will be ok to drill this?
High speed bits are intended and optimized (point shape, rake angle and material) for drilling hard, tough metals like low carbon steel. They will certainly make a hole in plaster dry wall board and wood and will not be damaged if you hit a nail. But they won't drill as clean and smooth a hole as a bit sharpened in a pattern better suited for these soft materials. Their tip will tend to wander around a bit as you start the hole and the hole will come out a bit oversized.
You may be able to find (and for less money) brad point drills (they have a little sharp point to stabilize the center of the hole as you start, and cut a circle out, first, then clear the rest of the hole)
or pilot point bits (with a smaller diameter drill point at thew tip)
are made for softer, and fibrous materials. These are often not made of high speed steel, in which case might get dull if you hit a nail.
They may be called, simply, wood bits.
Starters have a device, called a solenoid, which is a dual purpose device, it serves as a remote high voltage switch, so the high voltage doesn't have to pass through the key, and as a device to engage the starter motor's pinion gear onto the flywheel to crank.
When the solenoid is faulty, the rest of the starter, i.e. the part that spins to provide the cranking power, works fine, making a spinning or "soft power drill" sound, but because the solenoid doesn't engage the pinion gear onto the flywheel, nothing happens. You don't need a whole new starter, just a new solenoid.

i could verify the battery terminals for a loose connection or corrosion (seems greenish-white and flaky). each now and then loose or corroded terminals will enable low potential products such because of the fact the interior lights and sprint lights to artwork however the plenty larger modern-day required for the starter in basic terms won't flow. If the terminals are loose, tighten them yet be soft because of the fact the battery connections are produced from soft lead and could destroy. ideally, the battery terminals and connections must be bumped off and punctiliously wiped sparkling with a cord brush or a particular around battery terminal brush obtainable at any automobile factors keep. Ask somebody who knows what they're doing to help you, considering which you do no longer want to "short out" the battery by making use of touching a wrench to the "warm (purple) terminal and to floor (like the engine or physique). The spark will scare the h--- out of you and ought to burn you or reason a fire. additionally, did you be attentive to that pouring a cola on the battery terminals will rapidly dissolve that greenish corrosion. stick to the advice in the different solutions, too. all of them make sense.

The starter solenoid is failing to push out the drive pinion on the starter driveshaft itself. The driveshaft is turning but it's not engaging the flywheel which is what spins the engine. That soft sound of a power drill is the starter driveshaft spinning on it's own. "Not connecting to what it needs to" is the driveshaft not coming into contact with the flywheel.
You need to replace the starter.

It sound as though your gear in your starter is moving forward to engage your flywheel. That is the sound you hear. However, either it is not moving forward enough to engage your flywheel, or your flywheel has some teeth missing. The latter can happen when someone moves your ignition key to "start" while the car is running. When this happens you will grind off the teeth on your flywheel.
Try this. Try to rotate your crankshaft by hand by moving your harmonic balancer which is located at the bottom of your engine. Just follow your serpentine belt to the bottom of your engine. This will rotate your flywheel. You may have teeth missing on your flywheel and by moving it you may be able to rotate it to where no teeth or missing. I've had this happen to me.
