My father bought one of the early Miles ZX40 electric minivans #29 from 2005. (It is a Daihtsu Move from japan)

Read the epic story of getting it on the road here (OK not real epic, just a lot of waiting) http://ecomodder.com/forum/showthre...oking-miles-zx40-electric-micro-van-2973.html

Anyway it has a 4 speed manual transmission that is disabled and stuck in 2nd gear,
I have a rebuild manual for it and am working on getting replacement parts to re-place it (should the parts exist, still waiting for a reply)

Anyone willing to look at the rebuild manual? Maybe someone here who is more familiar with a transmission might be able to chime in with a possible way of reenabling the transmission. Currently it is missing the internal and exteral linkages. The Tranny assumably is for a standard Daihatsu gasoline Move mini van.

Info about the real manufacturer

this vehicle is probably a good candidate for field reduction also but I haven't ventured there yet. I did test the field resistance between D1 & 2 on the motor and end up between .4-.5 ohms which seems very high but it is a 48v 5hp motor. Maybe I need to find a better ohm meter than this cheap multimeter. Anyway does anyone have any idea what the "experimental" metal is listed at
miles35.com ?
He says resistance goes up as current goes up? Sounds like thin guage copper wire to me. I am working on getting a contactor and a switch to enable field reduction but I am not sure what guage or type of wire I should use, obviously I need to get an ammeter on this vehicle before I do any field reduction as the electronics are quite weak.

On my list is to add a real ammeter and voltmeter to this rig. Any suggestions? I am not sure if there is a bus bar in this vehicle to put one on but it really needs it if I am to start modding it.

Anyone else here own or deal with Miles ZX40's? I would love to hear from a been there done that as I am not sure what is really in place on the Miles Vehicle yet, I have it partway apart but don't have time to tear it down to the frame rails.

Basically I am looking for some real world information on the motor and drivetrain as I can't seem to find anything real usefull about their real world behaviors.

Even some help on field weakening methods would be greatly appreciated, my paticular motor has A1,A2 & D1, D2 which is a little strange. The motor seems sizable which seems strange that it is only 5hp when my D$D 10hp looks almost the same size. What types of materials or kits are available for field reduction? I need parts that are reliable not thrown together only to burn or short.

Thank You For ANY help

Re: 05" Miles ZX40 speed modifications, need tech info, have tranny rebuild manual

Usually "stuck in any gear except top gear" is an internal synchronizer problem. See if you can determine if a synchro hub has been pushed into second gear position but the fork that engages it is no longer in the groove and in fact is in neutral position. Good luck!

Re: 05" Miles ZX40 speed modifications, need tech info, have tranny rebuild manual

here are some pics of the transmission. I am working on rewinding the motor to see what that does..

I have a 48V model.

there is no way to get more speed on this vehicle the way it is... if you have a ZX40 (48V) the only way to increase the voltage.. but then again, new controller, more batteries, new charger, new cluster.. etc.. very expensive.

Thank YOU for the pictures, that is helpfull.

NO, it depends how much you want to increase speed; my goal was 35mph, right now I am up to 30mph just by changing out bad batteries, cleaning up & putting on better wiring where needed and by inflating the tires to 50 then 60psi.

I believe a simple field reduction circuit will get me the last 5mph.

Something to take care if you do increase voltage is that Miles lists the motor as 5600RPM max, the chinaman spec sheet for the motor says 6500rpm, I don't believe either but have a feeling it isn't much higher.

Many Zx40 transmissions have the 3rd gear taken out of them along with the fork there is a gentleman in Alaska with a Daihatsu part # list for the missing gears in the transmission, he is working on ordering a 3rd gear set from daihatsu to provide a higher speed for the ZX40, another method would be to take a Miles OR70 transmission which has all 4 gears left intact which could then be linked up to make a working transmission.

Also the "differential" (if you can even call it that) does have different gearings available, change the # of teeth on the 2 shafts and you can move up the van speed, you would need to find a 660cc Daihatsu sedan transmission/differential part # for the gears to accomplish this though.

Good Luck

Ryan,

I'm looking into a Miles truck also. Check evconcepts.com. It's a company in S. Carolina that builds electric vehicles and have done work on the Miles truck (which I think is really a Diahatsu truck that Miles changed to electric).

When you find out how to get your Miles out of 2nd gear could you let me know?

Thanx, Cecil

These guys have some Daihatsu parts
http://www.grparts.net/Daihatsu-mini-truck-parts-s/158.htm
Mostly for the ICE, but some suspension stuff too.


These guys are a large proponent of those mini's. They even answer questions.
http://www.superminitrucks.com/
Maybe they could help with the trans parts?

I wish I had one to put my AC50 in....LOL

My paticular rig is a ZX40 VAN, in any event daihatsu more or less used exactly the same transmissions in all its FWD models since the beginning of time, this means if you can find an antique Dahatsu Charade (which was legally sold here in the 80's and early 90's) preferably with a 3 banger ltr you will have a transmission ready to swap.

Also that website you link to is PURE spam, lousy healthcare crap

Cheers
Ryan
