sion case and has no tendency to spin. This design of clutch will<br />
withstand, without need of frequent adjustment, all manner of stress<br />
to which it is likely to be subjected.<br />
The perfect inherent balance of the engine would be quite useless<br />
if the other parts rotating with it were not balanced to the same<br />
degree. The <strong>Cadillac</strong> clutch is completely balanced before being<br />
assembled to the flywheel, so that it will preserve the smooth performance<br />
afforded by the<br />
famous <strong>Cadillac</strong> compensated<br />
crankshaft.<br />
The inertia of this clutch is<br />
remarkably low, insuring easy<br />
gear shifting, thus assisting<br />
Syncro-Mcsh transmission in<br />
obtaining perfect synchronization.<br />
The <strong>Cadillac</strong> clutch provides<br />
positive engagement wilh extremely<br />
light, pedal pressures.<br />
This clutch is of a two-plate<br />
design, and provision has been<br />
made for a positive release of<br />
the driven plates when the<br />
clutch is disengaged.<br />
Syncro-Mesh transmission<br />
In 1928, <strong>Cadillac</strong> engineers announced a new development in<br />
transmission design which enables gears to be shifted forward and<br />
backward without clashing. With this transmission, a novice can<br />
shift as noiselessly as an expert.<br />
The principle of this transmission is simple and positive. It provides<br />
three speeds forward and one reverse as in conventional practice.<br />
11 differs, however, in<br />
that all gears except low<br />
and reverse are in constant<br />
mesh. A coupling,<br />
litted with friction cones,<br />
is provided to connect the<br />
drive shaft with either<br />
the second-speed or highspeed<br />
gears by means of<br />
internal teeth. In shifting,<br />
the conical member<br />
engages a corresponding<br />
member on the second or<br />
high-speed gear before<br />
the teeth on the gear and<br />
Smooth performance and perfect balance of<br />
the <strong>Cadillac</strong> engine are secured by accurately<br />
weighing each end of Hie connecting rod and<br />
then machining to bring the weight within<br />
specified limits<br />
the coupling meet, causing the rotating parts to travel at the same<br />
speed, enabling complete engagement to be effected readily. The<br />
motion of the coupling and its cones is controlled by a special cam<br />
and two hydraulic controls to provide perfect tooth engagement<br />
at all limes. The positions of the control lever in the various gear
