[6pack] gear reduction starter

[Foster, Stan (HP IT)]

Hi Sloane, good question and a good description here

Gear-reduction starters

Chrysler Corporation contributed materially to the modern development of the
starter motor. In 1962, Chrysler introduced a starter incorporating a
geartrain between the motor and the driveshaft. Rolls Royce had introduced a
conceptually similar starter in 1946, but Chrysler's was the first
volume-production unit. The motor shaft has integrally-cut gear teeth forming
a drive gear which mesh with a larger adjacent driven gear to provide a gear
reduction ratio of 3.75:1. This permits the use of a higher-speed,
lower-current, lighter and more compact motor assembly while increasing
cranking torque.[1]. Variants of this starter design were used on most
vehicles produced by Chrysler Corporation from 1962 through 1987. The Chrysler
starter made a unique, readily identifiable sound when cranking the engine.
