We have released an extensive cooling kits test on our website: ebikestuff.eu/en/content/13-tsdz2tsdz2b-cooling-kits-tests Please have a look if you're still unsure if the TSDZ2/TSDZ2B motors require additional cooling

[@matthiasschuster9505]

The cooling test shows, that the premium conversion kit does solve the heat issue completely. It will very unlikely ever reach 70° - so I guess it is save, to avoid the complicated, installation of the temperature sensor?

[@ebikestuff]

@@matthiasschuster9505 If you don't stress the motor with the max power for a really long time you should be safe without the temp sensor. We didn't have any reports telling us that anyone had overheating issues with the premium kit

I just installed the "inset" after ordering it from ebikestuff. Perfect fit, very impressed. Very thankful for the video which was very detailed and spot on. I even got new torx screws instead of insex for the cover with my order without even ordering them, very happy about those!

[@ebikestuff]

That's great to hear. Thank you for the feedback. We really appreciate it. It took some time and effort to develop these cooling parts. It's very satisfying to see that people enjoy our products. Thank you

[@andreabrunetti2725]

the best cooling system that i have seen, great!

[@ebikestuff]

Thanks

[@dieseldan1]

I'm getting ready to install my kit. What size threading tap do you use?

[@ebikestuff]

2.5mm drill M3 x 0.5 tap - nominal diameter: 3mm, thread pitch: 0.5mm

[@davidzombori54]

Perfect job, I will send you for tuning when I will buy the motor. One question, can you also apply more grease on gears and blue gear specifically, or you think is enough and of good quality already from the manufacturer?

[@ebikestuff]

It is recommended to do a checkup once in a while but in general the amount of grease from factory is good enough. As far as we know, the grease used by Tongsheng is MOLYKOTE EM-50L. It is a good quality grease dedicated for that application. We have that in stock in our store if anyone is interesed. ebikestuff.eu/en/products/232-molykote-em-50l-grease-tsdz2.html

[@TK-OK]

Anyway to get a (premium kit) in the USA ?

[@ebikestuff]

Yes, just go to our store and order a kit with shipping to the USA: ebikestuff.eu/en/tuning-elements/217-tsdz2tsdz2b-motor-cooling-improvement-kit-premium.html

[@dieseldan1]

Can you connect a temp sensor to a 6pin controller?

[@ebikestuff]

Not really. The temp sensor relies on the throttle wires to send the temp info to the controller. The 6 PIN controller doesn't have those wires physically connected to the pin pads on the controller board. You can try to solder wires to the pin pads on the controller. Or use a bimetal sensor wired to the brake sensor wires. It will cut off the power when the bimetal reaches a given temp. It will act as a safety guard

[@Crand0m]

What is a fi3.2 drill bit? I can't find any info about the "fi" prefix online. Does it mean 3.2mm diameter drill bit?

[@ebikestuff]

Yes, it is diameter - "phi" symbol

[@kchortu]

How much does this effect the performance or longevity?

[@ebikestuff]

Depending on what you mean by performance. The worst you can do is to run this motor with the original firmware. OSF vastly improves the efficiency. The cooling mods allow for running the motor at a higher wattage for a longer period of time. Lower temperatures should result in a better longevity of the motor. If you haven't read our cooling kit test you can find it here: ebikestuff.eu/en/content/13-tsdz2tsdz2b-cooling-kits-tests

[@Crand0m]

I ran stock firmware at 750W without any cooling mod. My motor burned out a few days ago carrying a load up a hill after about 9 months of use. And here I am watching this video because I don't think you can do 750w TSDZ2B without cooling improvements.

[@Crand0m]

Sad I can't order the preapplied TSDZ2B kit with cooling to the UK! Otherwise I would just order that...

[@ebikestuff]

@@Crand0m Please shoot us an e-mail at [e-mail] and we'll see if we can arrange shipping to the UK for your order

[@marcinwlodarczyk7028]

jaki rozmiar gwintownika?

[@ebikestuff]

Do zamontowania radiatorów potrzebne są: Wiertło fi 2.5mm Gwintownik M3 x 0.5 - średnica: 3mm, skok gwintu: 0.5mm

[@ralph12d]

gluing is terrible advice, especially since blue gear often needs to be replaced

[@ebikestuff]

Therefore, gluing is used only where it doesn't affect later easy disassembly.
