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 🙏

[@Tdf353]

Hi there next time you need to trace a pretty accurate sketch of a part just put a thin smearing of grease all around the housing then gently place on cardboard or paper and firmly press it down and let it dry and you will have a perfect ish outline that you can then draw with a marker pen it's what I do with motorbike engine casings and always works a treat

[@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!

[@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!

[@rickm7209]

Excellent video. Brilliant idea to use the crank of the ICE engine ! I'm gonna use that idea. If the motor too lonng, try the Motenergy ME 1616. Probably just right for that van and 1/2 the cost of the AC 50 or Warp 9.

[@offtrackengineering]

Thanks! The 1616 is less than half the power of the already low powered AC-50. It probably wouldn’t do too well pushing this thing up hill

[@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!!

[@Ahmer4]

For tracing exact copy of flat shapes you can put paint on edges then put paper on it you will get exact measurements of the holes and edges.

[@travismicheal6452]

Listen hold the carboard against the tranmission and use a ball end hammer to tap out the holes and the flat hammer for the edges

[@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.

[@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.

[@nickreid5297]

I've bought a set of centre punches and am planning to punch directly through the bolt holes on the transmission and into the aluminium spacer plate. I hope it works!

[@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! :)

[@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!

[@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!

[@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

[@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.

[@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.

[@WADYNASTY77]

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

[@MrGsWorkshop]

Can you share the adapter plate pattern?

[@UA-DM]

Can something like this be done for Touareg GP?

[@FrankGraffagnino]

cool! thanks for documenting all of this!

[@offtrackengineering]

Thanks! Same goes to you!

[@JakeWest-1]

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.

[@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?

[@FLORIDIANMILLIONAIRE]

What does a surf band mean ?

[@Olive-oilien]

What about trying a shallow silicone mold?

[@alanblyde8502]

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

[@billshoff]

Very impressed with your skills.

[@offtrackengineering]

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

[@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.

[@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!!

[@sunshineken4062]

What electric motor did you use?

this is awesome

[@pogidonut5613]

Where’s your pilot bearing?

[@villaincolor6573]

this is awesome !!

[@CadPixel-why-not2455]

very interesting concepts

[@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!

[@pieterbezuidenhout2741]

Now as a 71 year 😂old dude I just wonder why go to all this trouble whilst a way easier method would be to couple the electric motor directly to a suitable ratio differential ? That would be much easier and save a lot of weight same time as well as friction through the gearbox . Just work out the ratio needed , get a small prop shaft connected an Bob's your uncle. Quite sure there will be less Gear WHINE coming from such a conversion as well.

[@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.

[@Daweim0]

Bruh it wouldn't hurt to be a little nicer. The motor manufacturer probably has torque specs for bolting their motor to things

[@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.

[@Daweim0]

Electric motors don't have max efficiency at all speeds though. EV manufactures probably put a lot of testing and thought into choosing the perfect gear ratio, not really practical for a DIY project. It also might be easier to keep the transmission instead of mate the motor to the drivetrain (especially if the rear differential is part of the transmission like it is in Sambars)

[@nickreid5297]

@@MarkSpohr Human cyclists have near to maximum torque when they stand on the pedal. But you still don't want to take off from a standstill in a higher gear. Gears are useful.

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