Are you able to post a step file ? Can you tell us how it initially failed, did a tooth break off ? Did you print the PLA with 100% solid fill ? Sure no problem, step file attached. It was the teeth that failed even though they were 100% solid fill. I was inspired to try the print by this chap on Y...

A while back I 3d printed a plastic main gear (helical) for the same reasons as you have mentioned in this thread, plus also trying to save weight. The design was created in Fusion 360. Step file attached, I can’t vouch for it’s accuracy as I’m no engineer. TSDZ2-Main-Gear.png The print was for test...

Thanks for the response, could the bearing that the end of the motor shaft fits into be worn? Is there a better bearing I can replace it with? It could be this bearing on the pinion gear. I fitted a brand new motor to a bike about a month ago which started whining after about 5 miles, when I got ba...

Interesting.. what's the diameter of your spider's hole then? not sure if this will fit mine as I still don't know which precise hole size I'm going to receive (from the web looks like 35-38mm). Perhaps it should have been better to order the spider with the standard hole to fit the standard rubber...

So, how did you seal your 38mm hole? I expect my 104BCD will arrive with the same hole. I wonder if there is any 38ODx15ID compatible seal. I had the same issue as you with the seal that comes with the motor would not fit the older style 108 BCD spider I had also ordered. So I didn’t fill the whole...

Just snapped an axle at 540kms. Anyone know where to buy just an axle by itself or the cheapest place to get a torque sensor unit? As far as I'm aware the axle comes as part of the torque sensor assembly: http://www.pswpower.com/ven.php?cargo.2016-7n-n002 Can you share any further info on where the...

Can I ask, will a TSDZ2 48v motor with the open source firmware run ok on a 36v battery? I can offer some feedback on the older software (v0.20.0-beta.1) with experimental high cadence mode enabled, I used a 36v battery on my 48v MTB to get me to the start of an organised ride and then swapped to a...

Just throwing out a quick line or two about my experience with the brass vs blue plastic cogs. Thought I would also add my experience with the brass gear: I ran the brass gear for a while, but after noticing the noise, brass shards and Casainho's post some time back about preferring the blue gear o...

Had my maiden voyage today, first time riding more than a few meters in the driveway. All went fine, but after around 20min a strange sound started inside the motor. When I had a similar sound it was grit in the teeth of the main drive cog (the one with the sprag clutch bearing in it). To check, re...

I have both the 36v & 48v motors on separate bikes, you can run both at the voltages you state but the 36v motor at sustained higher wattage will burn out. A real world example of this would be the 1 mile hill climb I do to a trail head near me, using the bike with the 36v motor at a sustained ...

General question I just installed a 36v tsdz2 motor and 850c display that came pre flashed with v19 of the OSF. Is there any physical difference between the 36v motor (as identified by sticker in motor case) and the 52v motor ? Are they the same motor. ? I’m wondering if I should have gotten the 48...

I also have the LCD3 on two bikes, one running v0.19 & the other v0.20, it is great that there is still potential development for this screen. Thanks to all those making this happen. I would like to draw attention to the motor runaway issue mentioned here and in a few other posts: https://endles...

Really appreciate the answer! Can you please post some pictures with the custom tools? My problems are now only with the pull/push of the sensor to the frame. Hopefully this is the part of the puzzle you are missing, I worked out how to get the torque sensor out with the image below from the repair...

In the repair manual (available here) they use a gear puller.

From my own personal experience I have always been able to gently ease it out by hand, Jbalat shows it in his video to replace the sprag clutch:

Hope this helps.

Hi, we are having real problems with downed motors, well not really drowned but we are having probably the worst winter for mud and deep muddles that I can remember and the motors are having to put up with some real adverse conditions. Never the less we are two motors down with the same symptoms. S...
