Not bad for 13,000 km without a fault. I recently replaced the second torque sensor after 15,000 km. A year after making this video, when I heard the squeaking again, I realized another possible cause of the squeaking. The shaft resting in the torque sensor also makes such a creaking sound, on the right side. This can also be eliminated by spraying a little oil spray. Maybe I should indicate in this video that it is not necessary to completely disassemble the motor, maybe a few drops of oil or if we grease the axle is enough. kzfaq.info/get/bejne/bbiTqsqQ35OaZ4U.htmlsi=Zm3ptU1tyKYgxxza And even this video is not completely accurate, because I think it's not the sprag clutch that squeaks, but the pedal axle as it rests in the torque sensor.

Thank you.

If all you hear is a squeak from the right crank, you may just need to pull the rubber seal on the axle and spray a little oil under the rubber disc. I don't have a video of this simple fix yet, because my bike started squeaking like this a few days ago. But the oil helped this time.

So I didn't have a squeak but I did have those wires shear just like yours. Trying to figure out how to solder in new ones.

Thanks for the info. Good to know, I might have to install it in a "PressFit 92" bottom bracket soon. I don't know if it's possible yet.

Thank you.

My crank axel broke two weeks ago at circlip groove. Fortunately, I still have a shaft from my old torque sensor. Even though the circlip grooves on it are a bit different, I was able to fit it with spacer rings. My plan is to make a new axle with a lathe, but without the circlip grooves and assemble it only with a spacer and shaft tightening ring.

@@mcelec7603 thank you. Not good you broke another. It seems like there are only a couple of suppliers of these spindles and they are out of stock or very expensive with delivery and tax. I'm going to investigate having a couple made (from stainless steel maybe which is stronger). Also without circlip grooves and try and shim the external gap between the motor housing and the crank arms.

I bought mine on ebay in Germany. The torque sensor on that one broke after a month when the wire rubbed out. I wrote the seller about the symptoms. The seller agreed to let me disassemble the motor, and when I sent him photos of the torque sensor, he sent me a new sensor. It was not easy, but if you bought the motor from a local dealer it might be easier to get it repaired.

Thank you. You can diagnose the motor based on my other video. kzfaq.info/get/bejne/bM2lmcJl2pzIYX0.html If the walk assist mode works properly, but there is no power assist while cycling, the torque sensor is probably faulty. if the freewheel in the blue gear slips, or if there is a problem with the electric motor or the control, then the walk assist mode also doesn't work.

I do a lot of muddy off-road and uphill cycling. There may be some places where I'd rather walk uphill on my bike, but I really enjoy the assist. The mudguard can seriously extend the life of the chain, since I fitted it I hardly have to clean the chain at all. I think the 350w model is plenty powerful enough. I tried it with a 52 sprocket and I could ride it continuously on flat roads at 45 km/h (with this wide off road tire). Since I prefer to use it off road I fitted it with a 42 sprocket. The manufacturer has made a few minor modifications already (mine is over four years old) and if you get a one year warranty you don't have to worry so much. Still, it's ok if you know how to install and repair it. Be careful not to hit the pedal while riding, unfortunately I've hit it a few times on protruding roots and rocks and that's probably why it broke sooner. The spacer is a really good idea in case the sprocket touches the frame, luckily I have enough clearance. This torque sensor solution is incredibly comfortable, it doesn't take anything away from the pleasure of cycling but it does make climbing hills easier. Unfortunately there aren't many options to choose from on the market.

What did you get after ? I just installed my TSDZ2 and I got this creaking straight away. If you didn't get anything I would suggest a rear gear hub motor but you must use a torque arm either side. Also, forget about the 250 watt "law" all the big ebike motor manufacturers run their bikes well over 250 watts and closer to 1 Kw at the peaks or even more, the most important thing is the 15.5 Mph limit. No one cares about power, it's the speed cut off that's important. You can set this speed limit yourself. I'm trying to compare my 2013 Gen I 50 Nm Bosch motor to this TSDZ2 at 52v and while it's nice not to have the speed limit I think the Bosch is way more powerful so going to try the Bosch again tomorrow on the same hill and see if I notice the difference but I think the torque rating of this TSDZ2 is nonsense.

I am ordering this tool: ```Knipex External Right Angle Snap Ring Pliers 90 Degree 1.8mm Tip Circlip Plier``` I think this should be the right size, I can post later with results.

At home I have a cheap, universal tool. It's not a perfect tool, but suitable for larger circlips. www.amazon.com/Combination-Universal-Internal-External-Straight/dp/B07NP2FFMB At workplace I have a professional Wurth set. eshop.wurth.co.uk/Product-categories/Circlip-pliers-set-type-A-B-C-D/31086022080204.cyid/3108.cgid/en/GB/GBP/

Ciao, dopo 8000 km di guida dura. Spero che il Deepl si traduca bene dall'inglese. :)

Hello, since I couldn't use the original mounting bracket because of the rear swing arm, I created this solution. Even so, sometimes the big fixing nut comes loose, so I marked its position with a marker pen. I also use a threadlocker on the lock nut and screws. So it's a bit tricky to mount the engine on a bike with full suspension, but I really like full suspension bikes because I mostly ride on unpaved roads. It is also important to note that the TSDZ2 can be mounted in a bottom bracket (innenlager) up to 73 mm wide.

The motor also comes in two other versions to fit bottom brackets of up to 100mm and 120mm

Well, it's not over-designed, that's a fact. My opinion is that the life of the torque sensor is 7000-8000 km maximum with intensive use. I have experienced several times that the stator wire has broken from vibration right at the stator's base. I haven't had a problem with too much power so far, and I pedal quite hard from time to time. But I'm very careful not to accidentally hit the crank arm on the objects. Since I replaced it, I have done 2000 km with the new one without any failure. Please watch the first two minutes of this video, it has some ideas on how to diagnose faulty parts, because other things can cause no assist: kzfaq.info/get/bejne/bM2lmcJl2pzIYX0.html

@@mcelec7603 thank you for the info, l'll try your suggestions

I have a Mustool MT315 microscope. It's a great help because I also repair logic boards.

@@mcelec7603 brilliant !!

Perhaps wear on the plastic gear on the other side, or a bearing or freewheel in the gear, or a bearing on the motor shaft, could be causing the whining sound. You should check the motor and blue plastic gear and bearings too. There is a video from the motor side of the drive: kzfaq.info/get/bejne/bM2lmcJl2pzIYX0.html

Hello, how do you mean? A little help to identify the problems: kzfaq.info/get/bejne/bM2lmcJl2pzIYX0.html

Surprisingly, since my last repair, the replacement of the torque sensor, I have done 3,500 km without a problem. Honestly, it's a little surprising. 😃 Bosch, Brose, Yamaha are certainly more reliable, but they can only be installed in a special frame, they are much more expensive and it is almost impossible to repair them at home. The TSDZ2 is easy to repair, cheap parts are available, and if you don't torture it, it can last a long time. The torque sensor works as wonderfully as Bosch, Brose or Yamaha. It is true, the TSDZ2 is not for those with strong legs, and it is easily damaged if you hit the pedal or the crank. That's it.

Unfortunately, I'm not familiar with bbshd, but the TSDZ2 torque sensor is a pretty overcomplicated thing, I think.
