Well I think it’s morning in Italy right about now. Here it’s nearly bedtime.
I puttered around the house with my fish today and lounged around playing with the computer. I made chicken soup from leftover smoked chicken, and after dinner I went outside and finished tearing down this transaxle for the trike project.

Because this is going to be electric it won’t need the reverse gear, and because it won’t be able to go fast, it really won’t need the other three speeds either.
That means that I won’t need any of these parts that I have marked. I’m showing the opposite side this time.

After removing all of that stuff and moving one spring clip on this brake drum shaft

I was able to put it all back together with just this set up.

I indicated the spring clip there as well. Moving this allowed me to remove a big gear and a spacer that I didn’t need.
So again here is the opposite side and it’s all complete and ready to close up.
The shaft with the hex nut used to be the trans brake, plus part of the intermediate gear reduction. I got rid of all that and now this is the input shaft of the transaxle.
This gives me a very beefy differential gear set up with a 7.5 to 1 reduction.
One revolution of the tires drives the trike forward 6’. The tires will turn 880 times per mile.
If I can supply 360 RPM to the input shaft It gets me 25 mph. 3hp electric might be plenty.
