Hi guys, I'm new here. I was looking for specifically information about the engine's output shaft. So the OD, the number of teeth, the ID and tooth width? I found some good information already about other aspects, but basically I've seen many conversions where a key'd motor sleeve is welded to a clutch splined hub and off we go. Is it that simple? does such a thing fail eventually? I remember working for a hybrid company we had problems with engine shlap on the rubber components of the motor connection. for example mcmaster's 6408K14 adapter. 2nd gen Acty km/h @ RPM 4th: 91 @ 7500 5th: 110 @ 7500 https://japancardirect.com/mini-trucks-and-kei-turbo-cars/mini-kei-trucks/spec-comparison-tables/ Another person managed to put 38 Thunder Sky LFP160, 3.20 Volt, Lithium-Ion into a similar truck I looked into some motors and found that in general you need to spend $800 to $3000 for a motor: here's a good one that has been used in other projects: http://www.evmotors.com.au/products/download/fb144.pdf but I see the 110km/h@7500RPM and I go... hmmm it would be nice to have a truck that can go up to 80mph so that's 128km/h. Even if you never get to use it, it would be nice. So anyway, what's a good /cheap strategy here?... I'm gonna tell you my little plan. I'm going to buy a salvaged nissan leaf and harvest its organs into the mini truck. There are some challanges that I can already see, but hey, its the cheapest way to go. plus I already know that the leaf's output shaft has some possible cheap spline sources.. sorry, I'm currently obsessed by the spline info.
