Show Itt Iffi FORD 01 IS MADE 10 TESTED Detroit, Mich., April 17 The work of turning out" Ford cars abounds in minute details of production which save precious minutes. A unique method is used to test cylinders to ascertain if they have been bored accurately to a thousandth of an inch, this simply allowing for the movement of the piston head. ' By old machine shop methods the cylinder was bored out and the piston pis-ton head turned and then one was fitted to the other. When Ford production pro-duction ran up into hundreds of motor mo-tor acrs per day It was obviously im-possfble im-possfble to test" in this way as clyin-dors clyin-dors .were bored in one portion of the plant while the pistons were being be-ing turned a great distance away. A device -was therefore worked out in which an electric globe Is used to, make the test. When a cylinder has j been bored to the correct size it is slid over an electric globe. A piston I guagc of the exact size of a piston I head is then slid into the cylinder and the tester examines It caVefull to ascertain if any light leaker around the guage. If there is no sigi of light it mean? that the cylinder has been bored .properly but if Hgnt shows the cylinder Is rejected as de- No matter how oarefully a motor has been tested before assembly it , Is always hard to start when the" as- sembling is finished. This has al-ways al-ways meant laborious cranking or the ' spinning of the motor by a self starter. j The difficulty was solved at the I Ford plant at Detroit in a unique manner. Pulley wheels revolving at i high speed were sunk flnsh with the ; floor in the assembly room. When a car has been set up (and in the rush season they are going through at the rate of 1000 per day) no effort is JM spent on turning the engine by ordl-nary ordl-nary means but the rear wheels are 'M placed on the floor pulleys, after tho gears have been meshed. This soon warms the motor and when the first puff of the exhaust announces that the engine is working Itself, the cav Is released from the pulleys -and jfl runs out on the loading platform. |
