TSDZ2 sprag clutch (crankset freewheel) replacing

When we feel like the chain is skipping and giving crackling noise at start but the chain isn't moving, it's time to replace the right side freewheel alias sprag clutch. When we feel the crankset is only slipping in quietly, probably sufficient to stick the clutch into the gear. The original threadlocker is not too good quality.
Don't use hammer to dis/assembly. The torque sensor, what is below the clutch, very sensitive.
Don't remove the smaller retaining ring, otherwise the torqe sensor may fall apart. To replace the torque sensor is more difficult job.
Check twice to the direction of rotation of the clutch before taking back.
When we are watching the clutch in built-in position and we are turning the inner ring in clockwise, the clutch has to turn the cogwheel too.
At installing the clutch into cogwheel, don't knock the inner ring only the outer. Use a tube of appropriate diameter.
