congratulations from a retired 90yr old engineer on a a no- nonsense and informative presentation . i try to keep up with the latest developments in auto engineering and your program is a delight to watch. may i add a comment: many bearings are ruined by bad installation procedure an here i must add that you do the correct thing : NEVER put stress on the balls or rollers. keep up the good work!
I think he only tapped on the outer races, should be fine! I too am an engineer, and enjoyed the no-nonsense videos. They were actually educational quality.
Thanks for taking the time to make these. Really interesting. Seems like an almost insurmountable job but you just slogging through it along with your experience makes it almost seem doable for someone. Can't wait for the next one!
You make this procedure very straight forward. I like your attention to detail, & fast forward when necessary etc). Pity the previous person didn’t. I suppose you could compare this procedure to an engine rebuild on an ICE. You have the tools and jigs ready at your disposal making the strip down and motor unit rebuild a piece of cake. I dare say the total cost of such exercise wouldn’t come cheap. Your expertise & skill was well worth watching right through to the end. I hope you’re going to train more technicians for the future. Great video.
Don't know if the newer EVs will have fewer problems or not, but 1.2 million of them were sold in the US last last year. There will be more sold this year, as compared to 119,710 sold in 2014, thenlast year this vehicle was made, so 10x as many.
WOW ! First time I've watched an Electric motor being removed, cleaned, greased, reassembled and reinstalled in the Vehicle. Very impressive ! Stay safe ! Stu xx
You have a great methodical way of working. Without a lot of fuss and pomposity. It's a relief to see you work, compared to all those self-overestimating TH-camrs.
At 25:00, My only suggestion would be to get yourself some brass hammers and brass punches for reinstalling the bearings. They will give you a much better "feel" for the installation. I'm an OG machinist. I'm interested in the overall costs to the customer for your 1st rate rebuild!?
I'm not an EV mechanic but I think if I learned to patiently break down my tasks into manageable steps and start each step with a calm, confident "alrighty," my life would go much more smoothly. You're a great example for the rest of us!
Man, while I was watching this, two things popped into this feeble old mind... 1) FINALLY he gets out the All 32nds weench to operate that fantastic puller. The All 32nds or Crescent Wrench gets so little air time nowaadays, and get so lonely. 2) I noticed the guy pacing behind you, smoking and chewing gum while playing with a fidget spinner. He was jealous of your patience. I think he said his name was Job. I have purchased 3 Tesla Model 3s, and am Jonesing fo an S. Tesla needs o find a way to clone a few thousand of you. I'm now a New subscriber, for sure.
Thanks fascinating video, with your skill set you will never be short of work. You are in a growth industry with little competition apart from high priced dealers, who would probably just replace the motor at a high cost.
This was very well done. You know what you're doing, and you talk about it clearly, without fuss. Your editing is great. No distractions. Thank you, Alex.
I find it kind of haphazard to not use a torque wrench for the bolts! A hydraulic press would be a good investment. Also a plastic rotor cradle foe cleaning to eliminate a roll off. Good content
Im really impressed with the quality of ur work!! Great job to put a Toyota back on the road and with the part u helped design it will run for 1/2 million miles without issues. Thank u for posting this.
Fantastic segment- thank you very much for this. We bought our first EV and I love learning all about the innards and systems of these things. Also excellent camera work, well lit, and good sound. Unfortunate to see the sloppy dealership work, losing and mixing up fasteners.
Thanks for your videos. I'm very impressed with your techniques and competence. One suggestion: When replacing the inverter cover, please make it clear how you are ensuring a good water seal, especially that outer lip. I didn't see that in the video.
You even torqued the wheels properly! That's the chef's kiss to wrap up the rebuild. Most guys don't torque them & go with the good n tite approach. I wish I could've been there in person as an apprentice! I would've helped you in whatever possible. You're very methodical like myself. Definitely liking & subscribing to your channel. Cheer's! 😊
Great repair. I would love to have you as my mechanic. Your diligence during repair is outstanding. I imagine the labor repair cost is inline with replacing an ICE engine but the actual parts cost is minimal compared to an ICE car. Great video as well showing every detail!
Further to my comment, I am so impressed in the manner you have done. Not boring to watch and so much informative. The only thing that I have noticed is that I have not seen you using Torque Wrench except for the screws for the wheels. Since I am used to seeing others carefully applying the required torque in each screws and marking same.
You did an awesome job and it was incredibly well explained. I really hope you keep posting more repair videos. Interested in learning as much as I can about repairing EV's and what kind of problems to expect.....What a treat....Thanks....
To clean the inside of round parts like that, I have had very good luck using one of those 3-arm drill-powered cylinder honers. They don't take off nearly enough material to hurt anything and will leave the inside extremely smooth and polished lol. If hitting it with a screwdriver is OK I don't see why a honer wouldn't be. We don't see people jamming screwdrivers into cylinder walls lol.
The five most expensive words in service industries: "Oh, while you're at it..." Closely followed by, "While you have it on the lift..." Wheel bearings, brakes, etc. Already have it in the air. If it were my car in my own shop, do it all.
Many thanks for these interesting insights. In Germany, the first workshops are starting to open battery packs to replace cells in the stack, but there have been few reports of EV motors with leaks in there cooling system. As others have written, the whole power units are probably always replaced. Sadly you don't say after how many miles or equivalent kilometers such damage becomes more common. I think many sellers believe that the EV motors will last the life of the car. I was able to learn a lot from your two videos, including the concentration with which each step in both mountings (out and back in) must be done. A great learning video and a perfect job, congratulations.
Most modern EV motors are oil instead of water cooled, so they don't suffer from this type of failure mode. The only other vehicle that I have heard of having coolant intrusion issues in the motor is the Audi E-Tron, though I have yet tear one down one myself... Apparently they use a face seal, which is a more robust seal setup, though obviously no seal is immune to wear. As far as longevity for the Tesla LDU, it varies, and also depends on when the motor was built, as there have been a couple different seal types... The earlier motors with triple lip seals hold up the best (though they have other issues on the "really" early ones), the most I've seen on one that was all original was close to 200k mi, but more often than not they start leaking well before that (probably more like ~100k mi). The later style single lip seals are WAY more prone to premature failure. I've seen some replacement LDUs start to have major coolant intrusion in as little as 20k mi (though I would say 50-60k is more common).
Your skills are very impressive. Everyone can see how the auto industry is changing right before their eyes. You are not just a mechanic like in the old days - you are an electro-mechanic. Thank you for sharing your knowledge with us. Your skills are truly impressive. Would you mind telling us how much that repair cost? Also, have any cars returned for a second time with a coolant leak? Thank you.
Great videos! Sad to see that the car needed a motor replaced (by dealer), and then what is essentially a rebuild by you at 76k miles. Though it was not as complicated as I thought it would be. I'm guessing the rebuild was $5k. Or at least it would be if I did it. Again.. Great set of videos!
Obviously you are a great mechanic but on some of the operations I think you should use a dead blow plastic hammer and a brass punch to set the bearings.
Remind me don’t get an ev of any make ,you did a great job on that motor but boy the technicality needed is more than classroom teaching as hands on is the way To go respect 🇬🇧👍🔧dave
I would love to see how Tesla would react to your technique on installing those meshed gears , that nuts , the average technician has no chance , Excellent work , excellent video, I’m an ICE man for life
Wow, A couple of bearings a nylon brush and the know how makes this superior to a gas combustion rebuild. You made it look easy which tells me it's not. LOL
Good job but I feel that this should be much easier and gentler on the part if you made a couple of simple gig pullers. Since you're doing this so often this maybe well worth the time.
Green loktite is self wicking. You should read the instructions on the bottle but you can just put the bearing in and then go around it with the green locktite to seal it in there. And save some rtv for the rest of us!
I can see you're a master mechanic with immaculate work ethic, much like the car care nut Ahmed, A mechanic with integrity will always have plenty of customers👍🙂...Javi G.
Extremely well done and documented video. Narration is clear and just what's needed. History of Tesla motor and other brands that use it is very interesting. I didn't see much torque settings. Do you torque to factory settings where needed?
Interesting that the coolant is supposedly causing the rust and corrosion!? I would expect the coolant to have antioxidation additives to either passivate or film protect the exposed metals everywhere in the coolant circuit. What type of coolant is this?
Have you ever thought about doing a Professional video where you include the torque values and actually talk through the minor issues of these rebuilds? Your video covers a lot of the particular issues, but I'm sure that there's many things that you didn't cover. I'm thinking that you could cover that in a Patreon type of video for guys who want to graduate into working on these cars, since EV cars aren't going away and are going to become more common. My son-in-law is a very experienced transmission rebuilder and so he might be the very audience that you could appeal to.

11:54 Cleaning this with dry ice blasting may be a more thorough clean + be easier / less manual.
Great video btw!

I was just thinking the same thing, I’m an automotive tech and cringe every time I see steel punches used on bearings
They need to bring back auto shop in high school. This looks so very interesting.
Watched both parts in their entirety, it's amazing that you just refurbished the engine and transmission in one fell swoop! I'm sold!
Well done, really. When you see the total labor involved it makes one appreciate guys like you doing it correctly.
I'm not an EV mechanic but I think if I learned to patiently break down my tasks into manageable steps and start each step with a calm, confident "alrighty," my life would go much more smoothly. You're a great example for the rest of us!
Here 4 part 2. You by passed the manufacturing moisture intrusion fault and provided the ability for oil cooling if necessary ,nice indeed
Your competence shines brightly. Thank you for the engaging rebuild.
Only wish I was younger, I’d love to go through EV tech training
I can always spot a good mechanic by how methodical they are. Nice job sir.

He's rebuilt hundreds, i'd say he knows what feels the right torque. It's not as if he's tightening head bolts or wheel nuts.
Great job well done. The only thing I would have done differently was I would have cleaned out the stator far better. It would have shined like new.
There is a new technique on a European channel on TH-cam
Im really impressed with the quality of ur work!! Great job to put a Toyota back on the road and with the part u helped design it will run for 1/2 million miles without issues.
Thank u for posting this.
Would have been nice to see some before and after resistance and mega ohm readings
Excellent follow on from the first video, thanks for this.

I really admire your skill and memory Alex.
Nice and thorough presentation. I feel like I learned something about EV drives.
yes... like never buying one😅😅😂
WOW, what an interesting look at these motors from a service perspective, cool stuff and thanks 😊
Excellent mechaniicing. Attention to detail is always the prime directive
you don't tell us a much cost a job like that time en pieces. Nice job you do.
Allrighty, thanks for the great video! Very informative.
I love your calmness, it makes me watch the videos longer👍
Man, it's worth watching your Hands and usage of Tools very closely 👍
Together with a no nonsense Presentation ....Great Job

brilliant hands on expertise
Thanks for your videos. I'm very impressed with your techniques and competence. One suggestion: When replacing the inverter cover, please make it clear how you are ensuring a good water seal, especially that outer lip. I didn't see that in the video.
Best video I've seen in a long time...clear informative ... very smart man... best wishes from Ireland...🌟👍
I really enjoyed these videos, very informative and a well executed tutorial for non-EV types.
Awesome job. Thanks for sharing.
Excellent video with superb detail. Love the coolant bypass, the fantastic motor stand, as well as clear and concise explanation of your process.
You even torqued the wheels properly! That's the chef's kiss to wrap up the rebuild. Most guys don't torque them & go with the good n tite approach. I wish I could've been there in person as an apprentice! I would've helped you in whatever possible. You're very methodical like myself.

Hi , Top vids these ones , thank you , cheers

I would just use a spiral reverse flute tap to clean up the threads instead of a drill bit
The five most expensive words in service industries: "Oh, while you're at it..."
Closely followed by, "While you have it on the lift..." Wheel bearings, brakes, etc. Already have it in the air. If it were my car in my own shop, do it all.
To do it all is reasonable. What I would look at is longevity (vehicle value) versus additional coast.

Not too far off, around $4,500 for a full rebuild like this typically.
Obviously you are a great mechanic but on some of the operations I think you should use a dead blow plastic hammer and a brass punch to set the bearings.
Not necessarily if you aren't directly hammering on the bearing
@@bubferner2146Except, that's exactly what he was doing with the main gear assembly bearings.
So impressive.
Une très belle présentation et une compétence au top! C'est passionnant. Merci de Lyon France.
I preferheating the outside piece and cooling the inside piece for a slip fit to install bearings. No pounding required.
More Videos Please, i Love IT

Don't you think after using degreaser/brake cleaner the rotor and stator will corrode again ? Thanks for the video.
Great Video, wear good gloves when using chemical sprays,
Great job! Fascinating videos.
Amazing, you definitely are a professional talented technician. Great job on that rebuild. 👍🏻
Well done !
