Key functional parts

p.133 from God delusion dawkins
".....To the evolutionist it is clear that TTSS components were commandeered for a new, but not wholly unrelated, function when the flagellar motor evolved. Given that the TTSS is tugging molecules through itself, it is not surprising that it uses a rudimentary version of the principle used by the flagellar motor, which tugs the molecules of the axle round and round. Evidently, crucial components of the flagellar motor were already in place and working before the flagellar motor evolved....."
rephase from YEC view of the same phenomena:
To the YECit is clear that TTSS components were commandeered for a new, but not wholly unrelated, function when the flagellar
motor was created by the Lord Jesus. Given that the TTSS is tugging molecules through
itself, it is not surprising that it uses a rudimentary version of the principle used by the flagellar motor, which tugs the molecules of the axle round and round. Key universal components of the flagellar motor were created , to be reused in other designs,like an engineer reuses key components to shape a different dimension of robot.
