7. Automotive Service
6. The starter drive is made up of a small, ____________ gear and an
________________________ clutch that work together to mesh with the
flywheel during cranking. The pinion gear is has just a few teeth (10) and the
flywheel it meshes with has over a hundred teeth.
This gear reduction provides a gain in torque.
