A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic. In the case of very large engines, the starter can even be another internal-combustion engine.
Internal combustion engines are feedback systems, which, once started, rely on the inertia from each cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two (intake, compression) strokes of the next cycle, as well as powering the engine's external load. To start the first cycle at the beginning of any particular session, the first two strokes must be powered in some other way than from the engine itself. The starter motor is used for this purpose and it is not required once the engine starts running and its feedback loop becomes self-sustaining.
Starter installation
Clean the armature and external drive mechanism with gasoline first. After cleaning, check whether the drive is flexible; when installing, apply graphite grease between the friction plates of the friction clutch, and apply organic oil to the threaded filament part; the starter is installed on the engine, and the distance between the end face of the driving gear and the plane of the flywheel is 3 5 mm is appropriate to ensure that the gears mesh correctly.
Fault check
The starter often has failures and phenomena that cannot rotate or rotate slowly. In this case, check the following aspects:
1. The battery has no electricity or the electricity is weak, so the starter cannot rotate or rotate slowly.
2. The starter thread is loose or off, and the switch or adsorption switch fails.
3. The brush is worn out or the brush surface is not correct, and the spring is weak, resulting in poor contact of the rectifier.
4. Excitation coil or armature coil is short-circuited or disconnected.
5. The rectifier is fouled and the mica sheet is protruding, causing poor contact between the brush and the rectifier.
Organization maintenance
In the process of starting the engine, the starter must draw in 344~400Ah from the battery. Therefore, in order to prevent the battery from over-current or damage, the starting time should not exceed 5s. In winter, it is easy to start difficult to start. Multiple starting times should not be too long, and appropriate intervals should be left in each starting.
Troubleshooting Guide:
* Battery - No Crank Condition
Ensure the Battery is fully charged (12.6 volts) and is the correct size for the vehicle
Use a Battery Tester to test the condition of your battery
* Terminals / Cables - Slow Crank Condition
Clean terminals with a Battery Cleaner and Battery Terminal Cleaner Tool
Make sure all connections are tight and replace frayed / corroded Battery Cables
* Switches - No Noise / No Start
Check Ignition Switch and wiring from switch to solenoid
Check Neutral Safety Switch
* Flywheel / Shims - Free Spinning / Noisy Starter
Check Flywheel and pinion for damage or wear
Check Starter Motor Shims and Starter Bolts for proper alignment and torque

Frequently Asked Questions:
(1)What causes a starter to go bad?
CAUSES OF FAULTY STARTERS: CAUSE OF FAILURE
Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically. Single-pinion gear, starter pinion or freewheel damaged.
(2)What can kill a starter?
As said, the starter will be damaged if you hold it in the start position for a long time and it overheats. As said, the starter will be damaged if you hold it in the start position for a long time and it overheats. Particularly if the voltage is low enough that the starter motor is not turning.
(3)How long will a bad starter last?
On average, a starter motor lasts for 100,000-150,000 miles. In many cars, the starter motor lasts for the lifetime of the vehicle; however in some cars, it can fail prematurely.
(4)Will hitting a starter make it work?
Tapping on the starter usually doesn't make the starter work if the solenoid is bad (think Nippondenso). OTOH, a starter with a bad armature segment responds well to tapping or banging with a hammer. ... If the starter is bad, then sometimes banging on it can persuade it to work.
(5)Will a bad starter drain your battery?
A 'bad' starter wont drain the battery while it is not being used to start the car, if that is what you mean. If the starter has a damaged commutator, it will not run at full power and so could mean that you have to turn the engine over longer to get the engine to start which will use more energy from the battery.
(6)Does cold weather affect starter?
Cold weather usually thickens the engine oil. Therefore, the starters require more power to start the engine. This brings in more load onto the battery affecting it severely. During winters, the battery produces less electrons as compared to warmer days.
(7).I have to change the starter fairly often in my car. What could be causing this?
A leak of some sort could be fouling the starter if fluid is dripping on it. If that's the case,
replacing the starter doesn't fix the leak so it's only a matter of time before the new starter fails.
