I really enjoy your videos and the animations you use to explain and simplify understanding of the subject matter. Last time I "repaired" a starter motor it was as follows; the loud click from the solenoid could be heard but then nothing, battery was fine so I removed the motor for bench testing. It turned out that the contactor plate/ring was not making the contact required for the electrical motor so bent the plate to ensure good contact, reassembled and re-fitted the assembly. I had the vehicle for another 5 years and it was still going strong when I sold the car.

You can diagnose a possible faulty starter motor by measuring voltage of the thick wire of the starter when you have someone turn the key all the way to start. You can also jump the 12 Volt signal "S" post of the solenoid to the large post going to the starter with a piece of wire or metal object to test for a faulty solenoid.

They were Bendix Starters in my day. The motor would throw a spinning pinion at the gear ring on the flywheel, using inertia to drive it forward on a spiral spline. There was a real possibility of causing wear and damage to the gear ring on the flywheel, after which the starter instead of engaging would make a loud shriek of clashing gear teeth. You could get the same effect by pressing the starter button/key when the engine was already running - guaranteed to do damage. Once the engine was running faster than the starter motor, the pinion would self disengage and run back down the spiral spline. There was a big spring on the shaft which helped this happen.

I used to work at a courier company full of sub-contracting owner operators. Failing starter motors were probably the most common failure. We would often crawl under the afflicted vehicle and bang the starter motor with a hammer while someone turned the ignition until the vehicle started and could be driven to the shop or the work be done for the day without turning the truck off. No idea why banging the starter motor worked, we just knew that it did and it saved many butts.

@Jimbo9008 2 жыл бұрын

Banging on the stater would tend to free up the stuck carbon brushes which have become to short to fully reach the commutator. This arcing causes the brushes to stick in the brush housing and become stuck.

Nice video. Though missing many things. The power doesn't go directly from starter key to starter solenoid. Rather, power go from starter key to relay, through safety interlock and from there, it goes to Starter solenoid. Safety interlock will make sure that car will not start in reverse. Please correct.

@norbertmachado6822 2 жыл бұрын

The ignition system on petrol engines is also energised by the second stage position on your ignition key switch. The third position is to energise the starter motor. It is a momentary switch which means once the engine has fired up the ignition key springs back to second position. In modern csrs the ECU, ignition units and coil packs control the spark and timing. I learnt about cars when carbs, distributors rotor arms and HT coils and off course points were used.

When the contactor plate makes contact across the terminals, the pull in winding becomes 0v because both of it’s become connected to the positive of the battery?

@danielmarkbuyoc9516 2 жыл бұрын

Question: Does the electricity for the pull in coil go through the windings of the motor to go back to the battery (negative side)? If it does, won't it start the motor itself already because it has a little potential voltage going through it?

Is there another way to explain the overrunning clutch and the rollers? That's the only part I can't get my head around. The engaging and disengaging of the rollers to protect the motor and pinion.

@DaDaDo661 10 ай бұрын

Same here

@isaacturrietta5142 2 ай бұрын

As far as I can tell, the pinion ger isn't attached to the shaft it spins freely. The overrunning clutch is what spins with the shaft. And as the clutch spins it's like a spinning rollercoaster on the rollers and they get plastered to the sides of their seats. The housing has ramps so as they get shoved to the side they run down the ramps and are shoved into the pinion gear and engage with it turning it. Then as the flywheel turns the pinion gear faster than the clutch the rollers are going to do what wheels do when you spin them; they run the opposite direction of the force you put on them. Do this put your hand in a big claw for the clutch, inside your claw put your other hand as a smaller claw for the pinion gear. As you rotate the big claw, imagine the rollers lagging behind and engaging. Then rotate the smaller claw faster then the big claw (engine is going faster the the starter). The small claw acts like the ground on the imagined rollers which spins them and drives them back up their ramps, disengaging them. Whoof! that was a mouthfull.

@isaacgraphics1416 2 жыл бұрын

The gear connected to the engine would be moving faster than the starter motor gear, so the little rollers mentioned at 6:20 would not engage. They stop the starter motor from getting damaged once the motor is running.

@autobreza7131 2 жыл бұрын

Since the engine/flywheel is spinning several times faster than the Bendix drive's operating speed (a few hundred rpm I believe) the flywheel will "grind" against the slower spinning Bendix gear when the gear tries to engage it. Hence, a major grinding of the gears until the key switch is released from the Start position. Or sometime the gear will engage and the Bendix will spin on it's sprag clutch which will sounds like a over-running worn-out bearing. Replaced many a starter with a ground down Bendix gear due to owners who thought the engine, which was running very quietly, was not running, when in fact it was. Some flywheels have ring gears that are more vulnerable to wear than the Bendix drive, resulting in a very expensive flywheel or ring gear replacement as well.

1:53 Don't you mean that because the pinion gear is small in relation to the flywheel the pinion gear must rotate fast but can have relatively little torque? AFAIK that's the normal way these "transmissions" work. Just think of the bicycle as an example: - high gear means big cog turns smaller cog (via chain) and needs high torque to get up to speed. - low gear means small/same-sized cog turns same/bigger-sized cog (via chain) and needs little torque but high RPM to get up to speed.
