How does the starter Bendix work?
The Bendix system places the starter drive pinion on a helical drive spring. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to wind the spring forcing the length of the spring to change, and allowing the pinion to engage with the ring gear.

What causes a starter Bendix to not engage?
The Bendix gear won't engage the flywheel or the flexplate to crank up the engine whenever there is insufficient power. You will need to check the battery voltage using a voltmeter or a multimeter. Under normal circumstances, battery's voltage should range between 12.4 volts and 12.6 volts.

What would cause a starter to not disengage?
The reason for this may be a bad switch or the cables may have a short. Please note that switches have been known to work intermittingly. Lastly, low voltage can also cause this issue. This may be due again to improper wiring, bad connections and a low or bad battery.
Why is my starter motor spinning but not engaging?
The most common reason a starter is not engaging is low battery voltage or a faulty starter motor solenoid. It can also be caused by faulty internal parts of the starter motor like the plunger or pinion gear.
What might cause a starter motor to spin but not crank or spin the engine?

Why does my starter just click?
You hear a single click Usually, this points to a faulty relay or solenoid, or a bad or jammed starter motor. Solution: Rock your car back and forth or tap the starter motor with a hammer and try starting the engine again. If this works, you are good to go!
When the starter spins but does not engage the flywheel which of the following may be true?
Starter spins but doesn't engage. Clicking sound : you hear it spinning with a click sound before it starts spinning. No grinding sound. The mechanism to engage the flywheel is faulty, probably it is seized, or battery doesn't have enough power to make the solenoid fully pull the mechanism (check battery charge).
What does it mean when the starter spins but doesn't engage?
If your starter motor is spinning but not engaging, one of the first things you should check is the battery voltage. If it's low, try charging the battery or jump-starting the car. If that doesn't work, you may need to replace the starter motor.
How can I test my starter without removing it?
The easiest way to check the starter on the vehicle is to use jumper cables to bypass the vehicle's electrical system. With the ignition turned off and the transmission in "park" -- and with all due care -- connect one end of the red/positive jumper cable to the positive terminal of the battery.

What is Bendix gear?
The name Bendix gear strictly applies to the spiral drive mechanism of an inertia-type starter . However, the term is sometimes used for the pre-engaged starter mechanism. Drive-mechanism faults can occur in two ways. The starter can spin without engaging with the flywheel , or jam in engagement.
How to free a Bendix spring?
To free it, compress the spring with a compressor tool available from most accessory shops. Do not use a vice instead: it can be dangerous if the spring slips.
What happens if a starter is not engaged?
If a pre-engaged starter does not engage, or if either type instead of spinning emits a dull > clunk , showing that it is jammed, there may be more serious trouble and you may have to strip the starter (See Stripping the starter motor ).
Can you check if a starter is inertia?
But a pre-engaged starter has to be stripped completely. With either type of starter, if you find no fault, it may be the flywheel that is damaged. There may be marks on the flywheel and corresponding ones on the pinion teeth.
