See Thru Starter In Slow Motion

I make a See-Thru Starter and Film it with the high-speed camera so we can better understand how a starter works. Every car and truck on the planet has a starter motor to start their engine but I've never seen inside of one until now.
In this See Through Starter, we can see exactly how each component works and what it does to start your car's engine every day and it was very interesting to see all the parts work in perfect harmony.
I also replicate what the starter gear does when you try and start your car when the engine is already running to see what exactly causes that crazy grinding noise.
This starter was from the Kohler Diesel

It's awesome that we have people like this with resources, talent AND willingness to share it with the rest of us. Stellar work again.

[@workingguy-OU812]

Yeah, his patience in other videos to try, break, re-make, and try again is respectable.

[@WarpedYT]

Thank you, I feel that sometimes it's kind of a disease, people ask me all the time why I don't do something else and I just can't.

[@workingguy-OU812]

@ You have made videos that probably millions have wondered about. On the flip side, even my 75 year old mother really enjoyed your camera in the car tire video. It was just a viewing angle that just about nobody ever imagined possible, so they never even conceived of seeing a video from inside the wheel/tire.

[@nzwedjat]

Good enough for me, basically what I thought was going on, and even with the problems, epic vid, thanks

[@Blue.star1]

@@WarpedYT let's make a 6 or 8 fuel engine vertical take off , after reaching 1km altitude , wings expand and rotors tilt and do horizontal propulsion , all aircraft body made from carbon fiber . Is there a discussion group for aviation ...

[@kellyblack4897]

As a mechanic let me say you just added concrete proof to something people like me have been saying for decades. Well done!

[@oires]

The cylinder where the magnets are glued need to be metal, it's called flux ring and it improves torque and efficiency

[@fjs1111]

You are right.

[@gabrielv.4358]

it contains the magnetism?

[@chris993361]

Came here to say just that. I imagine the torque is down quite a bit without the flux concentrating through the case. On top of which I bet the ground is not passing enough current either.

[@WarpedYT]

Yeah I meant to talk about that in the part in the video where I mentioned about the transparent plastic case and the ground, but I forgot and I didn't think it would make that much of a difference, it made a huge difference. I'm positive if I would have pulled the injectors out of the diesel it would have still spun it but that was way too much work as you could imagine. The magnetic flux is definitely a cool subject, magnetism in general is very mesmerizing.

[@WiseWik]

​@@gabrielv.4358 it's got electrolytes

[@boomer150]

Great video. When I first saw the thumbnail I asked myself "can that work?" and while you where building I figured the plastic wouldn't be able to handle the torque of the starter. Dads a mechanic. I know the power of a starter motor and how important it is to have them securely bolted in. Have changed a few myself. Sadly plastic is plastic and metal is metal. Worth trying. Cool to watch. BTW, I loved that clear printer.

[@justin_time]

Cool! Thanks for taking the time to create this, film, and post it!

[@WarpedYT]

Glad you enjoyed it!

[@AvionicsDude]

Yes, it was amazing! I kinda knew what was involved but to see it all in action is really cool! Thanks man!

[@ArjanoptHof]

Very educational. Thank you for the enormous effort you've put into this.

[@tyablo]

2:03 older, slower rpm starters actually were as you thought it was and they are much bigger than modern starters.

[@davidparker9676]

This will be a great video for auto students. Thanks for putting in the time and effort to make the transparent parts and the slow motion video.

[@WarpedYT]

I appreciate it, I wanted to make this so people could get a better idea for how the starter works.

[@kinasc1575]

​@WarpedYT Hi, older starters didn't have the gearing, and they really did kick when started. When I bought a recon 😅 starter for my now 30yr. old VW Golf, the test label stated it was 5000 Watts, at 12volts thats over 400 amps. To put that in perspective, an average household cooling fan is around 50 Watts, around 1/5 amp. at 240V UK supply.👍

[@NegativeROG]

As a lifelong mechanic, this is very cool to see. I've never _had_ to rebuild a starter, as I've always done the re-manned swap or bought a high-perf NiB.

[@workingguy-OU812]

Crazy video timing. I was just watching videos on taking apart my motorcycle's starter to grease the bearings (preventative), and reading up on it. Spent about two hours doing that, made breakfast, and this video pops up. Thanks, lol.

[@Williamxmr]

Great work! That 3D printer is sick. It's obvious now why the nose cone is so thick and why they crack sometimes. Next you should do a see through air hammer. Maybe then we can understand why there are no battery powered air hammers

[@williesmith8326]

But there are some starters that I've installed that don't have a nose cone. I'd like to see a side by side comparison of the 2 designs

[@GbArrtorius]

Hi. I am the guy who identified the lil turbo you were working with for one of your earlier videos. I love your work. Thank you for bringing all this knowledge to your viewers. God bless!

[@canadatransistor]

magnetic field collapsing such as spark plug coils could be a good topic. The phenomenon also happens with fuel injectors, starters, solenoids or anything with a coil including audio speakers. Very cool video - first time seeing your channel. Good stuff.

[@kenchorney2724]

The close-ups of the gear engagement are excellent! Very educational.

[@sseltrek1a2b]

the engineering that went into the starter design is pretty amazing, and really cool to see the innards (and see them working...)...

[@Marshadow1]

even if you were away for some time, its good to have a amazing quality video. those tiny sparks and pieces of metal flying around-- im on a 720P monitor and that looks just amazing in 4K muist be just wonderful.

[@xDarkAngelxc]

It's nice that I learned why it makes that sound when it's cranking the engine up. Thanks.

[@pastormartinez4676]

Uncle Tony’s Garage claims the problems when converting carburetor to fuel injection,come from the fact that the mixture doesn’t get heat as it expands while traveling thru the plenum,towards the cylinders. It would be nice to see the actual effect that temperature has on both a conventional intake plenum vs one fitted with a transversal tube carrying hot water through the plenum. Maybe an electric coil heater,such as the Diesel engine’s intake. Great video. Keep’em coming!

[@saysflushable]

I thought it was awesome! Thanks for the work. I consider your experiment a total success.

[@WarpedYT]

Thank you!

[@Leonardokite]

You never cease to amaze Matt! You always come up with the coolest ideas.

[@WarpedYT]

Thanks man! I'm glad you enjoy it.

[@kushkiller7108]

A video series on making a complete car see-through would be insane!

[@WarpedYT]

Ha I've been wanting to do that for a while... I just don't think I would be able to make my money back for that video unless I split it up into a bunch of pieces

[@kushkiller7108]

@WarpedYT true, the amount of time and money to make it happen is almost unimaginable. It would truly have to be a passion project

[@Mister_Facepalm]

Always wanted to know exactly what was going on when starting the car and what the noise was coming from so this is great thanks!

[@Toasty1992]

we have missed you!! dude as a geek ive seen scimatics and one disasemblmed but this is awesome!!!!

[@KeaganSlater-b1m]

Man, you deserve so many more views and subscribers. Like this video was actually so interesting and informative, just like most of the others. I really hope you get super big on KZbin, you definitely deserve it. With all the time and effort you put into all your videos. Keep going dude, love your videos.

[@fjs1111]

You did a very nice job with the form labs printing, that end cap looks like Plexiglass though LOL which is still the same material more or less.. I give you a lot of credit, lot of skill to get the fit so good. Learned something myself which I never thought about, most ALL of the torque when starting the motor is pushing against the top of the housing where it snapped off and of course a diesel engine has enormous compression.

[@WarpedYT]

Thanks for the comment, the material is similar to acrylic from what I'm told, yeah definitely the diesel compression had something to do with it, I wanted to remove the injectors but that's too much work you have to open up the whole top of the engine.

[@biglsells]

Your videos are the absolute best, keep them coming.

[@ROVER25X]

Matt, when I subbed to you all those years ago, it was for the cool slomo videos. These days, I'm just curious and amazed to what you are going to make next! Your fab skills out do all the slomo now. 😁

[@michaelskinner896]

Even though not fully successful, it was still very interesting and informative. Thanks for posting.

[@corkystorky]

nostalgic to see everything I learned from school, only this time to see what's going on inside the hero starter. Great job! 3D printer is also amazing!

[@WarpedYT]

Thanks, the 3D printers are the best

[@theodavies8754]

I reckon you did a top job of it. My first car repair was a seized starter on my mums mini when I was around 10 years old, that was 40+ years ago. I'm supposed to be a clockmaker now but there are so many things to fix between clocks and watches.

[@fluffsquirrel]

Now that's incredible! I've been wondering how the starter worked since I was little. Thank you man.

[@Robothut]

Not all starters are the same design. What you were thinking in the beginning is true. take a old VW bug starter, they use a Bendix design, the spinning motor pushes the starter gear out not a solenoid and there are no planetary gears either. much simpler. But as ICE motors got larger so did the requirement for the starter. Thank you for sharing with us, so cool seeing the clear build.

[@gabrielv.4358]

Welcome back!

[@WarpedYT]

Thanks!

[@Dale-TND]

I was just changing a starter so this video is PERFECT! Thanks!

[@Mikegastaldo]

Im the owner of starter pro's a small business focused on mobile starter replacement 😂...I was surprised to see you do this one... great job

[@WarpedYT]

Oh Nice! Well hopefully you'll show the video to your customers, even myself I have changed countless starters but for some reason I never took one apart.

[@TecraTube]

pretty cool bro. no thats bad a$$. pretty interesting to be able to visualize using the starting while its engaged and that o so familiar sound when the wife drives my car 😂

[@Qui-9]

Your first intuition about how it was built was actually correct for most motors. The one you have is a high torque motor assembly, it doesn't rotate as fast, but still as fast as it needs to.

[@theglitch99]

AWHY DOES BANGING A BROKEN STARTER WITH A HAMMER WORK? Having this channel in my library is so ppl think I'm smart!😅 thanx

[@jkbrown5496]

The spiral gear and spring seem to be where the magic happens. We see the starter gear bounce off the flywheel and turn just a bit so it can mesh before the motor spins up. Very cool. The contacts in the solenoid is just a copper disk pushed closed

[@travis.napier]

Always thankful to see new content from you. Was hoping the speciality clear material would make an appearance here but still glad the prototype LED did. Keep it up man.

[@ejcrashed]

Man, just keep doing all the crazy stuff you like to do, we will watch it with gusto!

[@kz6fittycent]

It's neat to see what our starters go thru many times a day. Very cool! P.S. Not boring at all!

[@macxj387]

Definitely need more videos like this. Informative and helps us better understand how mechanical components actually works.

[@ZMAN_420]

I just changed starters in a 09 F-250 5.4L and 18 Chevy Silverado L.S. 5.3L Excellent Video

[@MrArtVendelay]

That was totally awesome. I am not a mechanic but I have a good unstanding of most mechanical aspects of my cars. I thought the little starter gear that engages the ring gear of the flywheel was called the bendix. I didn't hear you refer to it as that. So it is the release of the key, or the button in todays cars the de-energized the solenoid and allows the bendix to return to its home position after getting the flywheel going. When the flywheel reaches a certain speed the engine begins to move on its own. Decades ago that was hand cranked like the starter cord on a lawn mower.

[@cat1stevens]

Fantastic Great ! i repaired a Toyota starter once, just at the electromagnet DC Connector, and cutted a piece of copper coin and soldered it on place, as this was very teared- it´s almost same load you will have when you weld, with electrodes ,and you can turn + and minus ,you will notice electrode on + you burn more into the material, and wit electrode on minus, you burn more electrode,and less into the material . Thanks for Great Video !

[@ratgreen]

I always enjoy these types of videos so dont be shy about making them. Educational and high production quality.

[@Debraj1978]

For any motor, the outer ferrous metal casing is not just for strength and rigidity, but also to carry the magnetic flux. Once you replace it with something non-ferrous, the motor is 100 times weaker.

[@WarpedYT]

I know I know... But I was being hopeful

[@jackdotzman2908]

Wow, you put a ton of time in putting this excellent vid together. Thanks you. We’re watching from Missouri.

[@slopoke22]

I think of a whole bunch of things like this. Pretty amazing how some parts dont break all the time and how much certain parts can take!

[@slopoke22]

Also, starters have some pretty serious power and good video. I also want a 3d printer so bad just broke, smh

[@WarpedYT]

It's actually crazy no doubt, I had a pretty famous director I worked with tell me that I completely changed the way he views mechanical machines, because I have shown him how much abuse and stress mechanics can actually take it's pretty amazing

[@chrisyalden]

I used to recondition these starter motors. This is a Bosch gear reduction type, not all have gears inside some are more simple. If you want you can take the gear apart that engages with the flywheel, it's called "the drive" it has a one way clutch inside it and rollers + springs and grease properly about 12/15 parts inside the drive, the factory used to have a drive room were 3/4 people rebuilt hundreds of them every day! The solenoid cap will push off if you push inside the big hole. Also the solenoid has 2 coils inside. 1 called the pulling the other called the holding. There is also a big piece of copper inside the solenoid cap, this is the switch to make the motor move.

[@iamdarkyoshi]

Very cool stuff. Amazed you could 1. remove the magnets from the donor and 2. wrangle them into the clear one. Shame it broke but I'm still impressed how strong it was still. Excited to see what comes next! I'd be interested to see inside a manual geabox and clutch.

[@wailingalen]

Bro this shit is so cool. See through anything is not only super rad looking, but like you said very educational!

[@andr27]

perfect. the video I wanted to watch since years

[@dehypnotizerz]

I can't believe what I just saw. A PLASTIC planetary gear housing just next to an electric motor, with the plastic basically touching the windings? I mean, not in your model, I mean in the original thing. That's built to fail! Thanks for your great vid!

[@WarpedYT]

I don't know, these starters last for a very long time. But yeah I don't think that plastic housing holds any torque at all

[@DarshaunSmithProductions]

Still a great video. One of the most underrated youtube channels out there!

[@alexlougan3148]

Finally I’ve been waiting for a new video from you💙 love your videos

[@JohnnyD1993]

2:05 I didn't realize they had drastically changed the incredibly simple design from the starters of yesterday. Neat.

[@harujp2]

your initial guess of a starter is correct like in a direct drive starter lol that's a geared started

[@mikec3260]

This makes a lot of sense, thank you very much for this awesome video and slow mo. A very cool design!

[@umakemerandy3669]

Yes! I have wanted this for a few weeks now. Thank you! Hope it turns out.

[@umakemerandy3669]

It was perrty great. Interesting how the gear stops spinning as it engages

[@MikkoRantalainen]

Great work demonstrating this kind of old school starter. The ingenious part of this design is that if the gears do not mesh, the starter motor will not be connected to electric power at all. All the spinning of the pinion gear is just springs inside the mechanism that gets pushed by the solenoid. Some pinion gears have some kind of forced release mechanism in case the solenoid hangs while in starting position. If the pinion doesn't release, the engine will spin starter motor too fast and the coils in the anchor will be thrown away by high g-forces. That will typically destroy the starter and may take the teeth from the flywheel, too. I think the video would have been more interesting if you had included info about what can go wrong and what happens then. The most common failure mode for the solenoid is facture in the fork that tries to connect the solenoid to the pinion because the spring in pinion is supposed to pull the solenoid away from the contacts.

[@maxvaessen]

This is awesome! ❤ looking forward to the next video

[@FilmFactry]

That is called a bendex gear. It can find its "mesh" with the flywheel. a regular gear may not mesh if not in perfect alignment.

[@andreworlando7374]

So happy you see a video from you

[@20bluebug]

Very cool video! Its cool to see what's going on inside something when it's working! I didn't know there was a planetary gear system as part of the starter.

[@just.jose.youtube]

Yeah! I'd say it's a reduction system to reduce rpm and increase torque...?

[@WarpedYT]

Thanks for the comment! Yeah, it's pretty crazy the inner workings of some of these starters!

[@20bluebug]

@@just.jose.youtube Yep, you are absolutely correct. :)

[@kleetus92]

Older starters were exactly what you thought, direct drive. A lot of them were also Series wound DC motors, not permanent magnet ones like this with gear reduction. Are the new ones better? Eh... considering engines keep getting smaller and smaller, it's hard to compare.

[@therealkirby101]

A see through body with a metal cap fpr the torque could work maybe? My starter must have had a few chunks missing, great slow motion footage in such detail. Great work 👏

[@deant876]

I have always just replaced starters, I had never taken one apart before recently. I was shocked to see the planetary gears

[@steveandsheryl]

worked out great. see through demonstrations/models are always real helpful. thanks

[@rileyh2675]

sick as always

[@tobymack2783]

Another great video. Glad it has audio, too.

[@atsimas]

3:59 it's an electromagnet with a spring. The electromagnet either attracts or pushes and the spring pusses on the opposite direction. Do not disassemble it.

[@vibrantvikas]

Thanks for bringing this, i was curious about starters, you got a new sub. 😊

[@mph6502]

Cool! On automotive applications the starter usually won't begin rotating until the gear is fully extended. Maybe because this is a smaller engine it rotates right away.

[@victortitov1740]

but how would it then engage if the gears aren't pre-aligned correctly?

[@genmaxpain]

the real damage while starting a re starting an engine whilst engine is still spinning is the flywheel's ring gear teeth will round and wear first as it IS a softer metal(teeth)(less soft than the starter's teeth)

[@WarpedYT]

I think that depends on the engine in this case the ring around the flywheel is hardened and the starter is the softer metal. If you look at the slow motion footage you can see the teeth actually chipping away

[@ChrisB257]

Lot of work and a great effort - always something to be learned and thank you. :)

[@Gazr965]

A clever design there to show internal parts working. Gaz UK.

[@Saltyarticles]

This is not the most exciting subject he said. This was awesome bro, do more see through parts. I wonder if you can do a see through turbine motor.

[@RK-kn1ud]

Hopefully when the Ford penny-pinchers suggests making a plastic starter housing in the future that somebody will show them your video and they actually watch it and change their mind. It took them a couple years to realize that plastic oil pans were a bad idea!

[@CarbonPhysics]

That was awesome. I didn't know I needed to see that. Thank you for sharing.

[@CWO3-uscg]

Nice work, as always

[@juantopo6682]

It is important to clarify that the engine only starts to turn when the pinion is engaged. And that is achieved with the contact shown in the solenoid mechanism.

[@tomclanys]

Thanks for the video. I think this could benefit from slightly more explanation or visualisation, like how the electromagnet/solenoid has the contacts to run the motor, at least as a basic diagram or a whiteboard drawing, but it was fun to watch either way :)

[@vladi_g]

When you pulled the magnets out of the iron case, the magnetic flux opened and the force of the magnets decreased. It is possible that even if the hull had not broken, the motor would not have been able to turn.

[@WarpedYT]

Exactly, I meant to talk about that but I didn't think it was going to make such a huge difference..

[@vladi_g]

@@WarpedYT It would be interesting to know the truth. One Russian DIY blogger (Negoda) makes a racing car and reduces the mass of all the elements as much as possible. In one of the recent videos, he was grinding through the body of an electric starter and doubted whether it was possible to make the walls very thin (reduce the magnetic flux). So far, he's left a lot of iron against the magnets.

[@mariebaxter473]

If you like seeing how stuff works ! Then this is one of the class acts on YT, reminds me of Mithbusters , just missing a hot girl on the switch gear.🤣
