Re: 2 Speed Xiongda hubmotor

It has become silent about this motor - did people stop using it? One of my motors stopped working recently. Looking inside revealed a sun gear with two teeth broken off. sun-gear-broken.jpg That made me curious how the gears look in my first motor ~ 10.000 km on it. You might remember, I had to rep...

Re: 2 Speed Motor

Can anyone share how the Lishui 48v controller and C600 LCD work with PAS. I would like to compare it to my KT48SVPR-XD15 / KT-LCD3 combo. With the KT48S / KT-LCD3, the "assist" from the motor increases with each PAS level by about 80 to 100 watts. The assist does only stop if I pedal har...

Re: 2 Speed Motor

Has anyone recently bought this motor? I'm wondering what the preferred controller / display combination is these days? Can anyone share how the Lishui 48v controller and C600 LCD work with PAS. I would like to compare it to my KT48SVPR-XD15 / KT-LCD3 combo. With the KT48S / KT-LCD3, the "assis...

Re: 2 Speed Motor

Thanks to all the help from this forum, I got the hall sensor replaced, and the motor working again. One bit of additional information for others if they have to do the same, there seem to exist 2 versions of the SS41 hall sensor, a G version and a F version. Xiongda told me they use the SS41F, so I...

Re: 2 Speed Motor

Thanks for your info on how to get the gear assembly off the axle. The pin actually doesn't move. I think the force I applied (banging it on a piece of soft wood) wasn't enough. After hitting it a bit harder down on a piece of hard oak wood it started to slide :D Now, while waiting for new HAL senso...

Re: 2 Speed Motor

I was wondering about hitting it on concrete too - took a a piece of soft wood for that - you can see the markings. From the other side the pin/key is visible too. It looks like the pin is wedged in between the gear assembly and the axle: P1210375.JPG The hitting/force might have made it even worse....

Re: 2 Speed Motor

Trying to follow those instructions, plus the video Bonnie sent me
http://v.youku.com/v_show/id_XMTM2NjA1N ... rom=y1.4-2
but still no luck in getting the gear assembly off.
Any further tips / tricks on how to do it?
Would an extractor tool / gear-puller help?
Thanks

Re: 2 Speed Motor

Then I probably should have asked first how to remove the planetary gear assembly.
Any suggestions for that?

Thanks, I just sent her an email - let's see what I'll hear back.
I have another question - probably for d8veh, how do I separate the rotor from the stator?
Thanks

Re: 2 Speed Motor

Thanks, those two answers helped me to open the motor. I placed the motor for half an hour in the sun, then removed the 3 cover screws (removing one is probably sufficient - I don't think they hold anything) added a longer hex screw to one hole, placed a ring spanner around it and started hitting th...

I still need to figure out the HAL issue of my motor. Can someone please send me detailed instructions on how to open the motor - if possible with pictures of the tool to be build to open it. I know there is information in this thread, but finding it in the 1000+ posts and putting it together it tou...

Re: 2 Speed Motor

Thanks for the pointer to that guide. When following the test procedure, I noticed the voltage between ground (black) and green always stays at about 5V when turning the wheel slowly backwards - or fast. Probing between ground and yellow or ground and green while turning the wheel slowly backwards c...

Re: 2 Speed Motor

The first bike I built with this motor almost a year ago did fail with a "info 03" failure today. It is a 48v version with KT controller and LCD3 display. After switching it on, I can notice a small attempt to start, followed by a blinking 03 info on the display. The KT-LCD3 manual lists t...

Re: 2 Speed Motor

Yes, they do have a cassette version.
The only issue it is pretty wide 145 mm for v-brake, 155 mm for disc.

Re: 2 Speed Motor

Thanks for the manual. I'm waiting to get new displays from Bonnie. Was the hot temperature you mentioned earlier due to the faulty display? Just asking, because would like to know if I could use the bike as is until the new displays arrive, or if using it with the faulty display could cause harm to...

Re: 2 Speed Motor

Then both C600 displays they sent must be defective - not a good sign. As a "safety" option, I ordered an extra KT controller with LCD03 display I used for the first two bikes I built. That one shows the correct voltage. I got a manual for the LCD03 display. Does anyone have a manual for t...

Re: 2 Speed Motor

Hi fellas, I ordered both controllers and LCDs, and have finished installing the system. Premilinary results are impressive. I opted to install the LiShui system first as the impression I got was that it was more economical, and the LCD just looks better to be honest. The only problem I am having n...

Re: 2 Speed Motor

I have 3 different type of KT controller right now.....but hey! no one have been comparable to the Lishui+KingMeter display. Dissapointing they moved away from the Lishui. The 48vKT controller I got about 2 months ago seems worlds ahead of the 36v (Auto was useless on this) previous one, though it'...

Re: 2 Speed Motor

[quote="menvert"]Maybe our calculations are out, I'd have guessed the cassette version would be the same total width as a 8-10s Freewheel version, it would be nice if they can send the schematic (like we have on page 1 or 2 of the thread)

These are the schematic I got for the cassette motor

Re: 2 Speed Motor

Thanks for those links. I was looking a few times at your original build thread already. So I guess I have a couple of options: A) Front motor 1. Buy a steel fork with v-brake mounts and change the front brake. 2. Buy a steel fork and widen it by about 10 to 12 mm to keep a disc brake B. Rear free w...

Re: 2 Speed Motor

Thanks for your suggestion. Let me see if I understand why you were routing the derailleur cable. Is it, because you want to change (increase) the distance one "click" on the shifter moves the derailleur; so it moves far enough to go to the next sprocket - assuming the sprockets are furthe...

Re: 2 Speed Motor

Yes, similar experience here. I also have to add that, contrarily to my primary opinion, I don't see the use for that much gears anymore. The motor is so powerful that it makes me shift 2 by 2, on a 7 speed freewheel... I agree, a 7 speed freewheel (21 gears total) is probably enough - especially i...
