TSDZ8 Torque Replacement - Tutoriel Request

[Syl1]

Hello,

Does anyone have a video or some images explaining, step by step, how to remove and, more importantly, refit the torque sensor on a
TSDZ8 ?

The only video available and PSWPOWER sent to me is incomplete; it shows the removal of the entire gear-sensor assembly and the refitting of the whole unit

The most important part – reinserting the torque sensor into the gear – is missing

I had an issue with error code 04H on the 860C display of a non-OSF TSDZ8

Purchased from PSWPOWER in November 2025 and used for leisurely off-road and soft mountain biking

PSWPOWER sent me the new part Torque Sensor (I regret, I should have sent the motor back, but the postage costs are quite high)

I already have a 2024 TSDZ8 and I’m happy with it; that’s why I bought a second one

Now, my TSDZ8 is unusable; New Torque Sensor is completely blocked and probably damaged, I’ll probably have to buy another one or get a new engine...

Hence my request for a step-by-step guide (removing the seals, circlips, etc.)

Thank you

I finally had to buy another kit!..

I want to warn beginner DIYers to avoid attempting to replace the torque sensor if they have to do it on this engine (TSDZ8).

You need the right tool, specifically a press—or even a professional-grade press.

And most importantly, the official video on YouTube is INCOMPLETE for now (20260710)
