Bump the focuser knob against something, that would be my guess. I have also seen many times people using excessive pressure on the pinion to act as a brake instead of adjusting the draw tube glide pressure...
The Tak pinion can bend (much like any pinion) at the thinnest point where it fits onto the bearing surface. Best way to straighten is to clamp it in a lathe and turn the chuck by hand using the blunt end of the tool to press it straight after locating which side the bend is on.
Or send Claude some $$$ for a new one.
