For many of us, the time has come for a good cleaning and refurbishment of our TSDZ2. This often involves the replacement of different bearings.
Hope this might help you.
What was the typical mileage which warrants replacement? Or just ride it into the ground.

Re: New "TSDZ2 Torque Sensor Central Motor"

Mine is the opposite. It starts to groan under moderate/high torque. I wonder if it would be possible to add a very thin like paint of maybe glass fiber to the main wheel, so the teeth would not rote metal against metal and would reduce the noise under load. Well, sometimes the noise is louder some...

Re: New "TSDZ2 Torque Sensor Central Motor"

Check the clearance between the motor and the frame on the chainside, if your frame is sufficiently wide on the rear bottom stays, the motor sometimes needs a small shim in there ( supplied with the kit ). Easy to tell if you can't see it, the motor makes a hard thud has it meets the BB as you drop...

Re: New "TSDZ2 Torque Sensor Central Motor"

For those not already convinced, I want to tell you how good I think the TSDZ2 really is. I just cycled up England's two highest legal mountainbikeable mountains. Both +3000'. Helvellyn and Skiddaw. I went for the 52 volt battery to minimise overheating problems on this type of ride, but the motor ...

Re: New "TSDZ2 Torque Sensor Central Motor"

fyi, how I managed to replace sprag clutch bearing at home. Very nice to being able to do it with such easily available tools!! I will put a link to this video on the wiki FAQ about the main gear!! In other home videos people were applying Loctite 648 before pressing in the sprag clutch. Is that ne...

Re: New "TSDZ2 Torque Sensor Central Motor"

What's the size of the external circlip on sparg clutch axle. Guessing by manual it's 30mm. Thinking about regreasing the secondary gear after 500km only, since it seems to be noisy again. Could be due to cold weather 7°C. On a previous day at 12°C there didn't seem to be any gritty growling noise s...

Re: Hardware temperature control tsdz2

TSDZ2 Fluid Cooling I’ve been working with this all summer. With several different leaks, different pumps, different tubing, different fluid routing, different fluids, and other difficulties. I finally have a fluid made to fill-up brushless Motors and it is working the way I wanted to from the star...

Re: New "TSDZ2 Torque Sensor Central Motor"

How was the max temp of 85C/185F determined? my motor reaches that rather quickly on a 27C/80F ambient kind of day like today wehn I'm climbing hills and such. I did some poking around, and it seems like a lot of DC perm magnet motors are rated to operate at temps nearly twice that hot, like 150C c...

Re: New "TSDZ2 Torque Sensor Central Motor"

Guys, I'm not sure what the problem is with the motor moving, if its fully located on the crank side of the BB and the non crank side plate is correctly installed ( yes you may well have to shim it with spacers to get the bolts correctly torqued ) and the large nut is correctly torqued, Its hard wi...

Can bbt-18 8 notch tool be used on TSDZ2 BB locknut. Decided to cut the one supplied with the motor so that it can be used while riding without removing the crank. Turns out it's too flimsy for that. Can't seem to find anything else (castle socket with 40mm inner diameter, cup and cone BB locknut is...

~88kg. Guess around 95 with camelback and other equipment. I would think bottoming out 160mm suspension on the other bike is a lot more weight on the pedals. Im not jumping the fatbike, but it is a hardtail, so maybe the shockload is higher after all...? Shock load is what will start a crack at the...

Very useful information indeed. This might be helpful also for displays that show condensation on the inside. Changing desiccant every 12 months would be too much to ask for. It wouldn't on hobby projects but it is impossible to do that on the "real" ebikes of my shop's clients though. Mi...
