The high compression cylinder head chambers on all Packard oars are milled out on this machine. Most manufacturers do not go to the expense of this operation, merely leaving this compression chamber in its rough state as when cast. Nevertheless, this final finish on all Packard motors equalizes the compression in each cylinder and also minimizes the accumulation of carbon because of the smooth surfaces obtained by this operation.
These machines finish-cut the Hypoid spiral rear axle driving pinion which is connected to the rear universal joint. This pinion meshes with the ring gear and drives the rear wheels. These machines are very accurate, cutting these gears to a manufacturing limit of one-half thousandths.
Here is another example of Packard's increase in manufacturing efficiency. This machine, designed and built in the Packard factory and operated by compressed air, saves the time and physical effort of several men and DOES THE JOB INFINITELY , BETTER. Besides lifting the cylinder block and dropping it on the upper half of the crankcase, using the connecting rod and piston as a guide, this machine serves as a check on many previous factory operations on these units.
CROSS-SECTIONAL VIEW OF CYLINDERS, PISTONS, VALVES, VALVE SPRINGS, ETC. - 578fr-D Simplicity is the keynote in the design of Packard engines for Packard motor cars. In engineering, as in art, the simple is always the most difficult to accomplish.
In this group the instruments are all accurate to millionths of an inch. They are used in the Packard factory for checking daily the gages and tools used in the manufacture of Packard cars. The LIGHT WAVE MACHINE, shown in the upper left hand corner, is the most accurate and absolute method of measurement ever discovered.
Packard cars are built in one of the largest, most modern and complete manufacturing plants in the entire automobile industry. It is a full mile in length from the storage buildings and huge body shop in the foreground to the forge and foundry buildings indicated by three clouds of escaping steam. In the center, at the right of the power plant is the service building where spare parts for all model Packards, past and present, are produced and stocked.
