A quick vid on must do upgrades if you have a tongsheng tsdz2 on your bike and are experiencing creaks, or to prevent them from developing or your crank spindle failing. www.djoccult.com streamlabs.com/djoccult1/tip
Amazing advice, thanks for the video! I'm in the UK, same motor and same problem, creaky squeak and a bit of play after 2200 miles... Given me confidence to have a good look inside...
This sounds like the exact same problem I have at the moment, thought it was the new saddle I had fitted rubbing as the noise sounded like plastic rubbing rather than mechanical.
Thanks for the recommendations! I was wondering if you have any info on the origin8 chainring. I'm looking for a compatible chainring that works with Tongsheng. I've found the thickness of many chainrings doesn't fit. I'm wondering if they might make an origin8 like yours that's bigger, maybe a 50/52t. Thanks for any info!
Today I added a second bearing to the non drive side. The second bearing did not set flush with the edge of the bottom bracket. It protruded about 3/16". I hope it would not give me problems using it like that.
Can you advise what the replacement chainring you used, BCD measurements etc. I would like to upgrade to a 52T but am a bit concerned about the clearance and offset.
I did the bearing mod a while back and yes, it's a good idea, but, in my case the fit is so sloppy it's debatable whether the inner race will be made to turn by the shaft rotation. Still, it does add more support and could be bettered with some Loctite bearing fit on the inner race if I was convinced the shaft rotates true enough.
Thanks for the reply. The only issue I have had with the motor is the silver securing nut working itself loose over time. I am unable to find a socket tool to fit a torque wrench for example to be able to know how tight it should be. Otherwise I am currently hitting the supplied spanner with a mallet to get a secure fit and eliminate any creaking.
@@djoccult Also I have found packing very thin slice of metal between the bottom bracket and motor shaft behind the silver securing nut reduces the movement, this has been pretty effective.
Just figured it out. The bearing is such a loose fit, that when I removed the sealing cover from one side of the bearing, I could just pull it out with a circlip plier. So I just pressed an other (same size, but unmolested bearing in. If I ever have to pull it out, I csn just remove the seal cover from the bearings side and pull it out again.
I think you'd need to remove it and cut a fresh groove to fit beyond the bearing, perhaps? Good question, I hadn't considered this and was about to order some.
Then you have to start at the drive-side and remove the circlips etc. Then you can push the axle out to the other side also pushing out the extra bearing...
I have theTSDZ2B motor but maybe tongsheng should of produced better quality steel on the spindles as I'm doing 40 to 50 miles daily and my spindles have worn at 830 miles but only the left spindle the right side is perfect , used same crank arms and bolts that came with kit , 1 thing I will say is you definitely need threadlocker blue with this kit
Me too. My spindle has rounded off slightly where it square tapers with the cranks, so there's a creak every pedal rotation. Fixed it by wrapping the spindle taper in a layer of aluminium foil, then putting the crank on. This old trick fills the gaps and usually works for months before needing reapplication. Torque wrench and threadlocker blue is also essential.
I think it sits behind the sprag clutch, I am going to attempt the mod in the next few weeks, I have attached a link to a Tongsheng video that shows the sprag removal, I think it will simply sit behind the sprag clutch. I will keep you updated once I have done it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XIzVzBbAfgc.htmlsi=3xg0TtxoH-pYZHhH
The TSDZ2 has been around for many years now i have a first gen one, not a single creak out of it, 90% of the creaks are incorrect tightening when installing and not fitting all the supports.
I was thinking about purchasing this kit from my first home build, but after watching this video, I’m not touching this motor with a 10 foot pole. You have to go through all these mods to make it run normally? Nah
