Many many thanks to both of you. I landed upon this video completely by chance (was looking for Prius inverter related videos), and I am thrilled that I did. The final bit where you put all the components together, and talked us through how MG1 and MG2 synchronize and drive the wheels either via battery power or via IC engine power was fantastic as well. I have always believed that opening up a machine is the best way to gauge quality, I think I now consider myself better informed about Toyota's hybrid drive systems thanks to this video.
Great video guys. There are a lot of so-called auto enthusiasts out there who have, for some insane reason, convinced themselves that hybrids are impossibly complex, unserviceable, frail, an affront to god, a harbinger of the apocalypse, etc. I wish I could force them all to watch your video, because from a maintenance standpoint, this is no more complicated than a conventional hydraulic automatic transmission - and as you guys mention, the Toyota HSD power-split drive is practically bulletproof. I've been in Camry Hybrid NYC taxis with 400k+ miles on them. They're incredibly durable cars.
+doctor zaius It looks SIMPLER than a conventional hydraulic automatic transmission - at least mechanically. I'm wondering about the computer control box which reads the 2 shaft speed sensors and decides when to start the engine, how much juice to give to M2 to control its speed, etc.
+Theodore Zuckerman It is. As a gearhead and embedded systems engineer, I see this video and want to go pillage priuses for fun brushless DC motor parts at the junkyard. I guess I might do that Sunday, actually... Anyone know if the motor-generators are bathed in transmission fluid, coolant, or neither? I'm guessing ATF or air since I see no coolant deposits, but I couldn't tell for sure.
BTW, with those lineman gloves, you are supposed to wear the accompanying leather gloves over them to protect the insulation. The rubber gloves by themselves can be easily damaged and should not be trusted with high-voltage.
this video is very useful, I wish you success always and don't get bored to share your knowledge with the world, greetings from automotive from Indonesia
I'm just a Prius owner and looking at this device I feel like I own a seriously advanced piece of engineering. This is seriously high technology. To the un initiated it looks like it came from outer space.
IF you are going to work on cast aluminum on the ground, lay something soft down before placing a mating surface face down. Cast aluminum gouges and scrapes easily and mating surfaces are machined. Please do not do what they did and place it directly on concrete if you run into a corroded bolt and accidently turn the whole thing you could destroy the surface causing premature failure of parts and or leaks.
Yes, great video. I really enjoyed watching this as an owner of a Lexus RX400h with basically the exact same HSD system. A few pieces of advice to go along with what Mishale said though. I definitely agree with her about the gearbox 100% but another thing. The metal tools as well should not be used on any machined mating surfaces, especially soft aluminum. No metal hammers to pop out gears either. They make hard plastic wedges and special plastic tools for that, plastic hammers to bang on the wedges and gears.
this was really interesting, I wondered how they work you guys did a good job, . you hit the hight points now the unit work,I have a general idea of how it all works now thanks
20:03 hpm magnetic motors also suffer less from heat & generate less heat on start up, and also use much less intitial inductive load which keeps the heat down & lengthens the life of the motor they also weigh much less .
verry verry informitive. i was under the impression that the motor and electric motor were on a seprate drive thank you verry much for posting this video.
@ 15:30 another reason why it doesnt run is because its "poling" without the rear bearing being located and the air gap being small, the rotor is being pulled by the magnetic field over to the stator
Thanks!, Jason the Tech in the Video let me know they go through extensive training on how to open these, we had the phone book sized manual sitting on the desk next to us. But being that we did not plan to put it together again, and that it was damaged in a wreck, we did the typical 'guy' thing and skipped the manual :)
yes , it's just good work habit to always do things properly even if it is broken. remember bad habits are easy to form while good habits hard to achieve. yes I'm guilty of typical guy thing too sometimes when I really want something done yesterday.
Also the orange wires are strict when u hook them up or what is the order if I just want to make sure they are correct. I replaced the battery and tried another inverter but so far engine wouldn't turn at at. I hear a click but never turn the engine. Even when the car in ready mood. Thanks for the help. Love the video

Thanks for the video, really helpful. My Mk1 Prius has a mechanically-operated park pawl that's not engaging for whatever reason, I'm trying to figure out if it's a massive job to get it out, in case it it broken, or whether it could be the cable isn't pushing it far enough to engage.
Awesome vid I have always been so curious what it looked like in side ...Mine is at 300K and I think it is going to my project tear down ..I think its an inverter issue so might not make to transmission ..thx guys !!
I am not worried about the electrons -- I want to see you put the whole dam thing back together - Can't you fix that burned winding ?? The wire is cheap ?
You guys are great mechanics. I did Prius inverter projects in 2010 but mainly on electrical part. Thanks for showing us what's inside a Prius motor assembly. By the way, you guys suck in electronics. Those are not AC motors. They are DC brushless motors which has to be controlled by sensing what rotor position is. The inverter fires DC pulses to the stater just a bit ahead of the rotor magnet position. If you apply AC like you did on this brushless DC motor, it will rotate forward and backward at the frequency of your AC source.
Don Zheng “by the way, you guys suck in electronics”.... and you sir just butchered the English language. Next time you berate someone, be sure to compose a sentence and or paragraph that’s beyond that of a 2nd grader...
@@nordicpride9708 You may have noticed that everything in your house and garage has been made by ppl who can't even speak your language, but who have your money. Are you proud of that?
using a VFD (Variable frequency drive) $150 new ebay 1.5-2 kw .5 - 400 hz would allow a gradual ramp up in speed for testing with no load a 30 - 50 kw VFD would allow the motor to used to full power (disable power split planet gears,speed encoder, 300v to dc bus in VFD for a pure electric prius
you can probably buy a cheap VFD (variable frequency drive) on ebay that will directly drive that motor off of 120V or 220V and allow varying power and speed
awesome video! ya'll seem to know a lot about the hybrids, would you happen to know where the atf fill plug is on 2013/2012 camry hybrid, and how much of it the car lost when the passenger side axel was pulled out?
So did you replace the bearing that had a gritty sound? If so did it fix the issue? I noticed something almost immediately after you split the cases, the "Chain" from the trans-axle to the final drive assembly was solid as a board! Drive chains are supposed to be loose and freely movable. Gen 2 used "Chain" drive, Gen 3 went to "Gear" drive. I bet that's why Toyota changed that design. From all the over comments doesn't look like anyone else noticed.
it is maybe like a torque converter when is spins then grabs , I just thought of that because I had one go bad at one time and that is what it does like slipping then grabbing but with a noise ,bang
you seem to be pretty good at this electric mechanics ,I would like to know why the total electric car systems do no self charge , like putting some kind of system attached to the wheel where there is already motion and to recharge the system in a totally electric system to keep the batterys charged without plugging them into a outside source to charge . any ideas on this at all ,
Because of the conservation of energy and law of entropy. Energy lost in traction and frictions cannot be recovered completely ( it can be but not in these times ! ). I mean not yet with this car, but it is coming. The technology is out there already, but the oil cartel oppose the wider application of a kind of "free energy". They don't want a free energy world. Nicola Tesla tried to implemented it about 100 years ago and they ruined him financially.
Great Video, Thanks for posting! One question I have about the transmission's operation that I just can't wrap my head around, is - Is there any kind of physical or mechanical brake on the rotation of the MG1 (the smaller one)? That power split device looks very much like an open diff. It seems like there's a lot of opportunity for power to spill out the back of the transmission (thru MG1) when the ICE and the main motor MG2 are turning at full torque, much like when you lift one wheel of an open differential off the ground and that unloaded wheel spins up uncontrollably. How do they stop that?
+64davrecon I'm honestly not sure, but you can use a brushless motor as somewhat of a brake - you just shunt the windings all to ground and it becomes an eddy current brake, effectively. It won't completely stop the shaft, there will be some slippage, but it will bring it nearly to a halt, which is good enough in this case. If you want peak efficiency you could even put that power into charging the battery to apply reaction force to the MG1 rotor instead of just shunting it to ground.
Hello guys. Thanks a lot for this video. Please do you have a tear down video of the 3rd generation gearbox? I bought a brand new Prius 3rd gen. from the US and shipped to Nigeria where I live. It started rattling almost from the very beginning. Initially I thought some objects had fallen into the fans but after a careful check I found nothing outside. Prius is not sold in Nigeria and I didn't want it completely damaged by quacks. I strongly suspect something wrong with the transaxle . I am a mechanic. I have checked inside the engine with a borescope and found nothing. I have changed the IGR and also chucked the intake manifold; both are pristine clean as the vehicle has done only 17000 miles in all. The car has been grounded for a year as the rattling got out of control and the Check Hybrid System won't let it engage the drive or neutral. It quakes heavily on starting and practically shuts down immediately with a warning to check hybrid system. Please I appreciate any advice. I couldn't get the service manual to buy.
Very confused. You should be able to get a manual. Not like a Tesla. These are much more complicated than a Tesla. But Tesla have problems with other people fixing their cars. For the life of me I can't figure out why? I wish I was a very good mechanic. Internal combustion engines are just too complicated for me. Electric is the way to go.
@@steve5912 Vehicles must be as efficient as possible to get from point A to point B as efficient as possible, with the least amount of pollution, there is no need for an unnecessary loud, inefficient V8
I have a 2004 civic hybrid qirh 184000 miles never been wreaked and when I start to take off from a stop I feel like a bang like a jump into gear type noise , it does it all the time when starting from a complete stop sometimes it is an easy noise or a harder bang like jumping into gear , like a trans slip , can you give me a idea of what this may be ,
at the beginning of this video . . . I am thinking . .. I would like to see this transmission go back together . . . and see . . . how well it works . . . once these two guys put it all back together . . . .Glad it's not my car . . .
Excellent tear-down, very informative, but why did you show the lovely 10k volt A/C safety gloves, then bang on the exposed A/C motor bear handed when it could be energized? :p
29:55 - How about using AC Volts range on that multimeter? It'd be interesting to see how many Volts a hand-spin would produce. I'd be interested in getting an MG1 &/or MG2 set, just for experimenting (not a burnt out one though! ;-) Neat video guys, but OH MAN, what a pain editing 5 minute chunks together! Looks like your full-frame shots are over-saturated... but you color-corrected on the crop-shots. Have you ever torn into a HiHy drive? I can't figure out where the MGR get its drive from?
My Prius is at Toyota at the moment, it makes a whining noise when it gets to 60 mph. They are telling me they have to replace the whole gear box as it’s one unit. Also having problem with the Hibrid battery switch. Yet they are telling me they have to replace the battery rather than checking the cells. Feeling frustrated.
Awesome video. MG2 is 30kW right? I bet I could make an awesome generator with a full wave bridge rectifier and a charge controller on MG2. Are the stators bathed in oil or are they internally cooled with tubing and passages?
Dude, you are beating on Aluminum castings with a regular hammer? You should be using a Compothane (Dead Drop) or a wood hammer for such operations as you can crack the casting or cause seating issues.
Great Job!!! Doug and Jason, I love the Prius and i want to buy a used one (2004-2009 model), how can i avoid buying a Prius with transmission or Hybrid system trouble from either owner/dealer? I live in the hot and dry climate of Phoenix AZ.
Is there a way to seperate/remove the transmission from the output of mg1 and 2? As in... would it be possible to take an out put from the motors and hack off the housing section of the transmission to possibly weld on an adapter plate... ?
Hi Guys, Great Vid! I have a question about how the ATF gets into and all over the internal parts: I did not see any seals to contain the ATF in the gears so I am assuming it goes all over the place in the trans too. So does the ATF get all over the electric parts too? And doesnt that make a bit of a electrical shorting hazard as the ATF gets old/carries metal dust and breaks down? I also suspect that high freq high voltage would have little problem finding an electrical path through the ATF, especially when it is full of metal dust from the gears wearing over time. Any thoughts on this? Thanks.
Think I figured out where my transmission failed. Somewhere between the chain and planetary gearset, seeing how it can't move or charge and makes a grind. That or a bearing went and dislodged or grenaded that main set between the motors
Many many thanks to both of you. I landed upon this video completely by chance (was looking for Prius inverter related videos), and I am thrilled that I did.

People are people. Too true.
Very educational video
Great job sir
Great Job!!! Doug and Jason,
I love the Prius and i want to buy a used one (2004-2009 model), how can i avoid buying a Prius with transmission or Hybrid system trouble from either owner/dealer?
I live in the hot and dry climate of Phoenix AZ.
You must be gay if you dont like a roaring v8.
Is there a way to seperate/remove the transmission from the output of mg1 and 2? As in... would it be possible to take an out put from the motors and hack off the housing section of the transmission to possibly weld on an adapter plate... ?
Wish the title of the video said what year/gen this was. Would save people a lot of time without having to watch to find out..
Hi Guys, Great Vid! I have a question about how the ATF gets into and all over the internal parts: I did not see any seals to contain the ATF in the gears so I am assuming it goes all over the place in the trans too. So does the ATF get all over the electric parts too? And doesnt that make a bit of a electrical shorting hazard as the ATF gets old/carries metal dust and breaks down? I also suspect that high freq high voltage would have little problem finding an electrical path through the ATF, especially when it is full of metal dust from the gears wearing over time. Any thoughts on this? Thanks.
Djdaudio what do you think caused the windings to burn? Is the rotor and stators immerse cooled in transmission fluid too?
Love it!
Think I figured out where my transmission failed. Somewhere between the chain and planetary gearset, seeing how it can't move or charge and makes a grind. That or a bearing went and dislodged or grenaded that main set between the motors
