When the engines leave the final assembly departmentthey are brought to a running-in room where they arerun-in by electric motor. The transmissions are completelyassembled with the engine so that the engines are run-inthrough their own gears. The first run is for 1 hr. inhigh gear. The electric motors which drive the enginesare direct connected and run at a constant spesd of during this period. The amperage required is from6 to 7 at the start of this run.

Following the 1-hr. run at625 , the engine is given a 4-hr. run in second gear,during which the engine turns at 1000 During the run the engine is gone over to locate leaks,scores and all the troubles which it would be possible tolocate in an open room of this kind with several enginesbeing run-in at the same time. When the engines are puton the running-in stand, a dynamometer inspection cardis attached to the engine. This card stays with. Packard single-six eng TESTING PACKARD Ene on the running-in staconnection with an electr the engine during this running-in process and during thesubsequent operations necessary to the completion of theinspection and tests. On this card are listed all of theprobable troubles which can be detected during the run-ning-in period as well as during the subsequent dynamome-ter inspection. Few notations can be expected on the cardduring the running-in process, which is purely a matterof working in the bearings and putting the engine in con-dition to run under its own power. The wattage requiredto run the engine or, in other words, its frictional re-sistance to being turned over by the electric motor is, ofcourse, entered, as well as the number of the jacks orelectric outfits employed in the running-in process. Theengine is checked over for tightness of all of the nutsand bolts which can possibly become loose. The motors used for running-in are Westinghouse direct-cu
