How I connected an electric motor to my transmission

[@o0REACT0o]

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 🙏

[@charlesfranklin734]

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!

[@joeschlotthauer840]

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.

[@benbonnell1930]

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 😎

[@offtrackengineering]

Appreciate it!!

[@steveclunn8165]

I'd like the crankshaft as a way to couple the flywheel electric motor. If some machine shop specialized in doing this they might be able to make a business out of it

[@jaygerig]

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!

[@importfanatik]

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.

[@offtrackengineering]

Thanks! Looking forward to posting more!

[@__zupreme__]

Such a cool project! Loving this series.

[@hellolendon]

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!

[@skybot808]

solid vid! keep the progress going!

[@offtrackengineering]

Thanks! Thanks for watching!

[@aaronbyard2051]

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

[@offtrackengineering]

Totally!

[@FrankGraffagnino]

cool! thanks for documenting all of this!

[@offtrackengineering]

Thanks! Same goes to you!

[@huevosrancheros11]

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.

[@JWest1]

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.

[@NewZeroland]

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??

[@offtrackengineering]

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.

[@NewZeroland]

@@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!

[@offtrackengineering]

Check out the evolving world channel on here! He’s just posted a whole series on a Pao conversion.

[@NewZeroland]

@@offtrackengineering oh snap! Thank you!!

[@billshoff]

Very impressed with your skills.

[@offtrackengineering]

the magic of editing, is I can cut out all of my mistakes.

[@actydcty4132]

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! :)

[@villaincolor6573]

this is awesome !!

[@markyormark7747]

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.

[@blackterminal]

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.

[@CadPixel-why-not2455]

very interesting concepts

[@battery_solar_ev]

art poster board is stiffer and thin ball ping hammer to make the holes and follow the edge. Its the old method of make your own gasket.

[@alanblyde8502]

Hey fella how did you progress did you sort out the gap issues, great work hi from downunder 🇦🇺🤙

[@gainmaster1]

Cool video

[@offtrackengineering]

Thanks!

[@Windraver]

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?

[@WADYNASTY77]

Out of curiosity could you not have just ordered a transmission gasket to use as a template

[@RonGrosinger]

Can you share the adapter plate pattern?

[@FLORIDIANMILLIONAIRE]

What does a surf band mean ?

[@JWONG-pu8ky]

Subscribed 👌

[@offtrackengineering]

Thank you!

[@Olive-oilien]

What about trying a shallow silicone mold?

[@Akanemo17]

Why you used the front camera to make the scan? The LiDAR is in the back

[@beforebefore]

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...

[@offtrackengineering]

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!

[@sunshineken4062]

What electric motor did you use?

[@Jtamerler]

Cool video dude r

[@offtrackengineering]

Thanks!

[@mwalsh5757]

Better to secure that paper to the housing with some double stick tape.

[@user-xt2jx1fr1z]

there are many mistakes the engine mount is a question

[@wugrut]

You used a LOT of loctite.

[@soofadivision]

find a nice piece of foam and a sharpy

[@aheadofthecurve2352]

For a channel that has engineering in its name there certainly isnt much engineering going on. Using a hand drill to drill sidewards holes, claiming there are torque "specs" for a prototype motor plate to attach to a motor, using hex headed bolts for said attachment without a washer(s). None of this even mentions the fact that he is taking the path of the most resistance by flipping the transmission onto the cardboard instead of laying the cardboard on the transmission. Not much in the way of work flow in fusion either...so much for taking a head on picture, importing it into f360 then scaling it to size and making the appropriate holes in their location. Its not hard nor does it take any substantial amount of time. As a user of Fusion360 since 2019 I can do something very similar (and have) in very little time. Quite frankly this video could be a case study on exactly how NOT to do things. Was anyone else astonished by the shear amount of extra work created by the guy in the video? So much for working smarter and not harder.

[@arilesereganiyu6694]

how well can by De's electric motor

[@daviddoherty4429]

Sorry mate your doing an interesting thing but my god you're to boring to watch.

[@MarkSpohr]

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.

[@damensutherland7081]

Do you think gears will improve mileage

[@MarkSpohr]

@@damensutherland7081 no. Gears change torque but electric motors have max torque at all speeds so gears aren't needed.
