When doing an EV conversion, one of the main things you need to figure out is how to actually connect an electric motor to the wheels of your car. This video explores how I solved that for my conversion.

For this conversion, I've decided to use an off the shelf motor -- an HPEVS AC 50 motor, that requires either just a differential, or a differential and transmission to drive the wheels.
My van is 4WD, and one if the parts of the van that I'd like to retain is it's 4WD capability. So I've decided to keep both the transmission and front differential. How do I connect the motor to the transmission? Well, by using an adapter plate to the bell housing, and either a rigid coupler from the motor output shaft to the transmission input shaft, or retaining the original clutch.

Man finally! I've been looking for some "random dude like me" who can also make good content to document his home made electric conversion ! Keep it going, I'll keep watching 🙏
3:00, spray the flange with machinists ink and carefully place the transmission on the paper, or spray the flange and tape the paper to the top of the transmission and flop the paper over like a hinge to the face of the flange, or take thin cardboard and place it on the flange and hit the carboard with a rubber hammer making an impression from the flange to the cardboard.
13:30, toaster oven next time for even heating.
Bro I want to honor you for your dedication to this project! I have a
1976 Rolls Royce that I’m interested in converting to electric, you have inspired a great deal, success to you in your hard work!
This is where I'm at right now converting my grandpa's old Datsun pickup. I had the same idea and I'm looking to source a blown out crankshaft -- glad to see that method worked for you!
ive been wanting someone to use a manual in an ev forever. would be cool if you could tune the engine to rev *almost* like a ice engine but also take advantage of its instant torque and rpm
Totally!
Such a cool project! Loving this series.
This is cool! Any chance we would be able to get the file for this adapter plate? It looks like what we need for our own project. Lmk! :)
this is fire, huge props for documenting your successes and failures. keep up the great work bro, i'm excited to see how this project comes along 😎
Appreciate it!!
cool! thanks for documenting all of this!
Thanks! Same goes to you!
very interesting concepts
solid vid! keep the progress going!
Thanks! Thanks for watching!
Great video! You've gained a new subscriber for sure
So many smart ideas in here which will save so many people so much hassle off the back of your year long endeavour!
Looking forward to watching more of your videos!
Great video! Its helpful and inspiring to see all these challenges and failures and how you work through the problems and dont give up. Looking forward to seeing more.
Thanks! Looking forward to posting more!
Very impressed with your skills.
the magic of editing, is I can cut out all of my mistakes.
this is awesome !!
Cool video
Thanks!
Very nice. I always wanted to EV swap a kei car. Specifically the deckvan keis with both van and truck bed.
I originally had considered keeping my CRX transmission for the same reasons as you for my EV conversion but since i was using the Nissan Leaf motor, I found the axle coming from the Honda transmission wouldnt clear the motor and ended up using the Leaf single speed transmission instead. Make sure your axles will clear the motor with the transmission. The benefit of mating the transmission is stock axles can be used but if they dont clear, you'd end up needing an intermediate shaft which is just custom axles all over again.
What do you plan to use for batteries?
an inch thick bellhousing plate is insane lol. Good news it wont flex, thats always a plus. Other than that, I thought the AC 50 motor would be smaller, glad I didnt pick one up for my project. I am converting my dads 1979 Kawasaki kz650 SR into an electric bike. Going to build a 20kwh battery pack for it and have either a mid drive motor or a hub motor. Depends on the battery size and shape of it. I may have to build two battery boxes and link them together via giant cables. but either way it will work out to be around the same weight of the original engine and trans, and theoretically it should go somewhere around 250 to 400 miles a charge. Zero bikes are 16kwh max and get around 300 miles per charge. So I should be a bit better depending on the output I set the motor up with. It wont be a 75kw bike, more like a max of 30kw of output.

Thank you!
I am concerned about no pilot bearing for the transmission shaft inside your flywheel hub. Also I am concerned that you are relying on the HPEVS motor bearing for the axial load caused by the the pressure plate engaging the clutch. I believe what is needed is an additional thrust bearing to take that axial load.
I have no pilot bearing. Just wouldn't fit after adapters etc. My car though hasn't left the driveway. Legal costs are high in New Zealand to make a conversion road legal.
Aw man I fell behind on your videos! "I'm a guy who knows nothing about anything" is something I can relate to haha. Kudos for attempting such a challenging project! Also, is that your Pao??
Haha after getting up to speed on your videos I noticed a similar mentality lol. That was my Pao! I had to sell it, this stupid project has taken too much money.
@@offtrackengineering I bet. A friend's Pao has a blown engine and he was asking about electric conversions, but I haven't even really started mine yet so I can't say how difficult or expensive it'll be. That would be sweet though!
Check out the evolving world channel on here! He’s just posted a whole series on a Pao conversion.
@@offtrackengineering oh snap! Thank you!!
Cool video dude r
Thanks!
What about trying a shallow silicone mold?
Why you used the front camera to make the scan?
The LiDAR is in the back
What electric motor did you use?
It still seems like using a salvage Leaf drive assembly would be less work overall... and a lot more reliable, and more powerful, and smaller, and more integrated and... and...
I promise you it’s not smaller, it would be really hard to mate it to the existing drivetrain as well. As far as reliability goes, a salvage motor doesn’t come with warranty and support. HPEVS does, but to each their own!
Better to secure that paper to the housing with some double stick tape.
find a nice piece of foam and a sharpy
You used a LOT of loctite.
there are many mistakes the engine mount is a question
how well can by De's electric motor
As someone else commented the axial load needs to be addressed. The old gas engine has a bearing design that can take the lateral pressure from the side load that happens every time you step on the clutch. Those clutch forks put a few hundred pounds of sideways force on the electric motor bearings which probably has not been designed for and you will have premature bearing failure.
Sorry mate your doing an interesting thing but my god you're to boring to watch.
Real EVs only have one gear and don't use a transmission, clutch or flywheel. It's just extra weight and something complicated to break.
Do you think gears will improve mileage
@@damensutherland7081 no. Gears change torque but electric motors have max torque at all speeds so gears aren't needed.
