Thanks for all your videos. I am probably 2 years out from starting my own conversion but I will probably be using a Leaf motor for it, so these videos are a great source of information!
Great vid. If you count the teeth you’ll find the gear ratio is a bit over eight. Also the differential actually is the part that contains spider gears. You only see these if you’ve removed the gears particularly the large one.
Those motors from Nissan leaf are going so cheap in the used market now, I am looking into building a boat with those. its just a steal compared with the maritime electric motors on the market.
It has a small number of bolts holding the ring gear, seems it would not handle a lot of torque? The toyota highlander rear drive unit is similiar with a built-in much smaller motor and it looks just as strong as this gearbox even though it has only 50hp i think.
Around the 6 minute mark you mention a reservoir which is at the top side of the case (bottom of the screen as it's inverted). The large gear throws oil into that reservoir and it drains down onto the gears through the little hole. That might be important and certainly won't function as expected upside down.
That's a very good point. I'm also trying to get more information on how much oil goes into the gearbox and how full it gets (is it filled to the brim or not) as that should help me understand the impact of that section and whether it would still work upside down. That said I'm still not certain if that is the approach I'll take.
Great video Shane and thanks again for sharing. This helped a lot to figure out how to manually release the electronic gearbox brake. I removed the small brake motor and released the parking brake by hand with a 12mm socket. Did you find out how to control the brake motor electronically?
Thanks. Glad it was helpful. I haven't managed to control the brake motor electronically yet, but it is on the backlog (along with a bunch of other tasks) once I do it will definitely be something I do a video on.
Would it be possible to run a rear propshaft off of the gearbox to replace an original gearbox in an EV conversion? I'm looking at potential weight saving and I think this box would be lighter than my current one which is probably around 80kg or so.
I believe Nissan advises a specific ATF, but most should do. I am still trying to decide what to use long term, I will probably got with a relatively viscous oil as I am running this in reverse and want to give as much wear protection as possible. But that will cause a slight drop in efficiency. It’s a balancing act n
Do you know if you can easily remove the brake actuator and reinstall without major issues? I rotated the gear case 90° to install it in my Tacoma. I want to remove it to fill it with oil.
Hi Shane do you have a idea on how to disengage the parking break without breaking down the whole unit I picked up a motor for my VW bug project thanks
I haven't figured it out yet. Mine came disengaged so I have been reluctant to tinker with it until I have figured more out. Once I do, I will of course do a video on it.
I would put about 1:4 of Lucas oil additive in the fluid if it's going to be upside down, it will add stickiness to the fluid causing it to climb the gears and lube everything, in stock location the fluid is thrown up to the 'resivor' and channeled to the bearings, the 20 oz or so of Lucas should allow lubrication without the stock channeled lubrication, beunr it's inverted! I'd love to get one of these motors and gear boxes, maybe motor only, and maybe connect it to two leaf batteries, for extra range, and possibly allowing more current to be pulled from the battery, I have no idea of the voltage limit of the inverter, it would be nice if it could be boosted about 100v I'm not sure if there is current limiting due to battery capabilities , either way, adding battery capacity would double avalible current, I need to study these further, I'm going to buy a leaf Battery to add to my house to power it, break it to a 24 v system, maybe I'll eventually get to building a car,
Hi James, thanks for the tip, I'll look into that additive. I've been trying to figure out how to keep the box properly lubricated while running backwards. I've heard estimates that the inverter should be okay up to 450v which may allow me to close the gap between the leaf stock power and that of the Porsche. I'm planning to build up to this voltage and test these theoretical limits in the real world. Good luck with the leaf home power project.
Hoping to, I haven't taken much of a look into what type of signal is needed to control it. But as long as it's not too complicated, I'd like to get it working.
The 2018 leaf maintenance schedule says to check 'reduction gear oil'. Is that just a plug on the unit to check its fluid level? Do I have to take the entire flimsy cover off the bottom of the car engine to get into it? Thanks Performance EV!
Yes, there are three plugs on the unit. The one the side near the base is for draining the fluid and the one close to where the CV Joint goes in is for checking/filling the fluid. I haven't seen how it looks in place in the car, but I think you have to remove the undertray. I found this post when I was researching the gearbox it may be of help - www.mynissanleaf.com/viewtopic.php?t=25076

Thanks, I'm glad this series is proving useful.
the latest engine is 150hp wait for the next one is 200 hp
Check out the Spark EV motor as well. The coaxial output shaft can make packaging a bit easier.
nice lession
Informative video, Good effort.

You deserve alot more subscribers

You are a nice guy
Ciao che riduzione ha il cambio ??quanti giri bisogno dare al ingresso per avere 1 giro in uscita ??
Just checking, did you ever figure out how to operate the parking brake motor on the gearbox?
Great contents.
Can you help to how I make a design calculation for the ev gearbox

Hi, may you share the diameter of the larger gear shown in 4:35? Thanks
What advice would you give to gearbox oil? What would be the most appropriate and best? thank you :)

Hybrid ceramic bearings or normal steel balls bearings?
Can I meet you to discuss an idea I have. I live in London
How much does it weigh?
you mentioned 8:1 reduction of the Gear system. But whats the speed of the Input Motor.
The stock inverter control limits the motor to 10k rpm. I'm hoping to get it spinning faster than that to give a higher top speed.
I would put about 1:4 of Lucas oil additive in the fluid if it's going to be upside down, it will add stickiness to the fluid causing it to climb the gears and lube everything, in stock location the fluid is thrown up to the 'resivor' and channeled to the bearings, the 20 oz or so of Lucas should allow lubrication without the stock channeled lubrication, beunr it's inverted!

Are you going to keep the parking lock?

@@PerformanceEV If you suss it out let us know. I've not been able to find anything useful. Mines coming out.

I have changed the fluid after 170k Km and it was worth it.
