The 24-tooth clutch gear (http://peeron.com/inv/parts/60c01) seems to absorb
motion if it gets stuck. However, at least in the Cherry Picker (8292) the
clutch gear is almost right after the motor, before the worm screws... what is
that for?

The same reason. The part is effectively a torque limiter - it even has the
nominal torque limit printed on it (2.5-5.0 Ncm) - where it is placed in the
gear chain simply decides how much maximum torque is available at the output.

It should perhaps be noted that there are now two versions of this part, and the
newer version no longer has a torque range embossed on the side.

The BI for 8292 shows the older part, but mine came with the newer. My 8297 both
came with the newer version, and shows the newer in the BI.
