I’m resto-modding a 1960 SWB and here are some options I’ve come up with…

I like the LT230 transfer case because it is very versatile - hi/low, locking diff, many ratio options. But then again a dual motor would be nice 😊

Hi again Chris,
Your torque table really helps allot! 🤩
When looking at it again I understand you might not have any reduction gear in between and limit the max rev instead, right? (about 5500 rpm) It should give enough or same torque as original 4479 at 1 low. This is great even though I love torque. But maybe I shouldn't worry to much about it... ? See also that you are planning to use the newer 150hp 320Nm Leaf motor? Right?

With the LT230 and the 1.6 gears and 4.7 diff it gives you ~ 8:1 final drive ratio which is near to stock Leaf plus you get low for crawling. Yes I’m planning on a newer motor. A Leaf Plus would be nice 💪

I was dissing the two motor solution because I thought I had to wait for the 3:1 Torque box, they are currently working on. But looking at your figures and calculating with 2*250 Nm *1,9*4,7 I end up with 4.465 which should be enough?? Or what do you think? 3:1 =7050 Nm is madness!! maybe?? 😵 (Please correct me if I am wrong, I am not an mechanical engineer...) And a top speed of 168 km/h @ 10k rpm, which I will never use. I will not run it at higher revs than 6000 rpm (100 km/h) most likely. Then maybe I can use the Black box which is cheaper... Thinking loud now.... 😏

That model is with drive shafts in stock position. I think there is plenty of room….
The thing you have to watch also is axle strength. Series are well known for snapping them🤔

Hi Jens, nice work and thanks for sharing!
I see in the 1.0 that you connect the motor direct to the transfer box. A few questions pop up in my head that you might be able to answer.
How wide is your motor? It must be pretty slim to fit to the transfer case I guess? (My Leaf motor doesn't fit to the original gear box but maybe to a LT230)
Do you have any reduction gearbox in between motor and transfer box or do you run it direct? How high can you rev it in that case?

I don’t have a motor yet but do have a LT230 with 1.6 output so I can’t confirm fit. My plan is to mount the motor through the PTO so there is no centre tunnel and put the motor under the seat ( nice and clean)?

I think the LT230 has a 5,000 RPM limit so I might need the 1.2 gears if I want drive it on the highway?

Wow, it looks like you’re really going for it 👍👍

Really interested in the mating of the EM57 and the LT230
Does the motor fit on the front input? Thought it would be really close…
My LT230 didn’t come with a drum brake so I would go with a disc anyway. Wondering if the motor could be rotated 90 degrees to give you more room?

Anyway, I’ll be following your posts with great interest…

I saw that in the drawing and thought it was an interesting approach. If the space between the frame rails in the middle of the wheelbase wouldn't fit any of the battery anyway, this is a clever way to free up space in the engine bay and transmission tunnel.

Thanks Brian. I makes it nicer for middle passenger too, but unfortunately I can’t take all the credit…
