WEBVTT Kind: captions; Language: en 00:00:00.000 --> 00:00:01.001 Your life worked. 00:00:04.000 --> 00:00:07.000 Music 00:00:07.000 --> 00:00:13.001 Not so 00:00:13.001 --> 00:00:16.001 many years ago, the automobile was considered a luxury. 00:00:17.001 --> 00:00:21.000 About the only time it received an airing was on Sunday or a holiday. 00:00:22.000 --> 00:00:25.000 Today, millions of buses, trucks, and cars travel the 00:00:25.000 --> 00:00:26.001 highways from coast to coast. 00:00:27.000 --> 00:00:31.001 The number of cars on our city streets offers proof that for millions of people, 00:00:32.000 --> 00:00:35.001 automotive transportation is almost as much a necessity as a house. 00:00:37.001 --> 00:00:41.001 The good, all-round service man is really four mechanics in one. 00:00:42.000 --> 00:00:45.001 He must be able to make all repairs on the engine, such as repairing 00:00:45.001 --> 00:00:47.000 or replacing the camshaft. 00:00:48.000 --> 00:00:50.001 He must understand all types of engines thoroughly. 00:00:51.000 --> 00:00:55.000 Or although all gas engines are fundamentally the same, differences have been 00:00:55.000 --> 00:00:58.001 developed in the various makes of cars, which the mechanic must know. 00:01:00.000 --> 00:01:04.001 For example, in cleaning out carbon and grinding valves, he may work on the L 00:01:04.001 --> 00:01:09.000 -head type engine one time, while the next engine may be the overhead valve type. 00:01:09.001 --> 00:01:12.001 Both types provide efficient power, but the problems of 00:01:12.001 --> 00:01:14.001 adjusting them are totally different. 00:01:17.001 --> 00:01:20.000 A good service man is also a machinist. 00:01:20.000 --> 00:01:25.000 In an emergency, he may be called upon to make completely some minor part, which 00:01:25.000 --> 00:01:27.000 may not be in the stock of repair parts. 00:01:29.000 --> 00:01:31.000 The superior service man is a welder. 00:01:31.001 --> 00:01:34.000 Through accidents and even ordinary usage, parts 00:01:34.000 --> 00:01:36.000 are broken and have to be repaired. 00:01:36.001 --> 00:01:41.000 The expert welder is valuable to any garage, and often concentrates on 00:01:41.000 --> 00:01:43.000 specialized work at very good pay. 00:01:44.001 --> 00:01:48.001 In addition, the all-round service man is an electrician, and must have the 00:01:48.001 --> 00:01:52.001 knowledge and skill to keep the automobile's electrical system in working order. 00:01:53.001 --> 00:01:56.001 So without the spark to fire the engine, there would be no power. 00:01:57.000 --> 00:02:01.001 In the early days, electrical energy was supplied by dry batteries, but the car 00:02:01.001 --> 00:02:04.001 of today carries its own generating and storage plant. 00:02:05.001 --> 00:02:10.000 The storage battery is of low voltage, so a coil-in condenser is necessary to 00:02:10.000 --> 00:02:13.000 step up the current enough to jump the spark gaps and the spark floods. 00:02:14.000 --> 00:02:18.000 The coil-in distributor also must be tested and kept in proper working order. 00:02:19.000 --> 00:02:23.000 Besides the ignition system, there are the lighting and starting circuits which 00:02:23.000 --> 00:02:25.001 sometimes need the services of a competent mechanic. 00:02:26.000 --> 00:02:30.000 The use of heaters, windshield wipers, and radios has further increased and 00:02:30.000 --> 00:02:32.001 complicated the electrical work of the service man. 00:02:34.000 --> 00:02:38.000 Because of the high speed at which vehicles travel today, the care and adjustment 00:02:38.000 --> 00:02:41.001 of brakes is a serious and vital part of the service man's work. 00:02:42.000 --> 00:02:46.001 The safety of the car on the highway largely depends on good brakes, along with 00:02:46.001 --> 00:02:48.001 correct and accurate alignment of the wheels. 00:02:51.001 --> 00:02:55.001 Radiator repair and general care of the cooling system is important in making 00:02:55.001 --> 00:03:00.000 cars run efficiently and economically, so soldering is another of the many kinds 00:03:00.000 --> 00:03:02.001 of work the service man must do. 00:03:08.001 --> 00:03:13.000 In the larger garages, the man who becomes expert in servicing engines may find 00:03:13.000 --> 00:03:15.000 specialized work on engines only. 00:03:16.000 --> 00:03:18.000 There are body and fender shops which employ men 00:03:18.000 --> 00:03:19.001 who are specialists in that land. 00:03:20.000 --> 00:03:23.001 There are battery and electrical shops, and other shops which make brake testing 00:03:23.001 --> 00:03:26.000 and wheel aligning the principal part of their business. 00:03:27.000 --> 00:03:31.000 For any of these jobs, a thorough training and general service work is valuable. 00:03:32.000 --> 00:03:36.001 There is an opportunity in the larger garages for the service man to advance to 00:03:36.001 --> 00:03:39.000 service manager or to become a troubleshooter. 00:03:39.001 --> 00:03:44.000 Besides technical knowledge and skills, these jobs require the ability to meet 00:03:44.000 --> 00:03:48.001 the public, to make a good impression, and to explain clearly the work that needs 00:03:48.001 --> 00:03:50.001 to be done or that has been done. 00:03:51.001 --> 00:03:53.001 Some service men become automobile salesmen. 00:03:54.000 --> 00:03:58.000 If they have sales ability, they are usually successful, because they have the 00:03:58.000 --> 00:04:01.000 advantage of really understanding the cars they sell. 00:04:04.001 --> 00:04:11.000 If you enter the automotive service field, your first job will probably be as a 00:04:11.000 --> 00:04:13.000 helper in the shop of a general service garage, 00:04:13.001 --> 00:04:15.001 or it may be in the parts department. 00:04:16.001 --> 00:04:20.001 You will have a chance to learn the names of the many parts of an automobile and 00:04:20.001 --> 00:04:22.000 their relationship to each other. 00:04:23.001 --> 00:04:27.001 You will learn about lubrication and other operations in automobile upkeep. 00:04:28.000 --> 00:04:32.001 While doing these jobs, you must be alert to learn everything you possibly can. 00:04:33.000 --> 00:04:36.000 You must also study constantly in your spare time. 00:04:37.001 --> 00:04:41.001 As a basis for study, there are numerous service manuals put out by the 00:04:41.001 --> 00:04:45.001 automobile manufacturers to help train service men to do their work correctly. 00:04:46.000 --> 00:04:50.001 These manuals are full of accurate information, and they're interesting to study 00:04:50.001 --> 00:04:53.000 because of their detailed diagrams and illustrations. 00:04:54.000 --> 00:04:57.001 There are many good books on automotive service in your school or public library. 00:04:58.001 --> 00:05:02.000 Be sure to select books which are up to date, however, as automobiles 00:05:02.000 --> 00:05:04.000 are constantly being improved. 00:05:05.001 --> 00:05:09.001 Most automobile manufacturers provide training courses for their service men. 00:05:10.001 --> 00:05:12.001 Regular training conferences are held for 00:05:12.001 --> 00:05:14.001 employees in the more up-to-date garages. 00:05:15.000 --> 00:05:19.001 The manager, shop foreman, or some other expert, discusses the newest automobile 00:05:19.001 --> 00:05:22.000 developments and how to service them properly. 00:05:23.001 --> 00:05:26.000 Movies and slide films are sometimes shown in the local shop. 00:05:27.000 --> 00:05:29.001 Manuals for further study are provided along with the films. 00:05:30.001 --> 00:05:34.000 You should never miss such opportunities to learn if you expect 00:05:34.000 --> 00:05:36.000 to become a successful mechanic. 00:05:37.001 --> 00:05:42.000 Another way to learn while working is to attend evening classes dealing with the 00:05:42.000 --> 00:05:44.000 fundamental principles of the automobile. 00:05:45.000 --> 00:05:49.000 These classes are conducted in the larger towns and cities by the public schools 00:05:49.000 --> 00:05:50.001 or other local organizations. 00:05:51.001 --> 00:05:54.000 In some of them, courses in shop practice are also given. 00:05:55.000 --> 00:05:58.001 Don't fail to take advantage of these courses to help you prepare 00:05:58.001 --> 00:06:00.000 yourself for the better jobs. 00:06:02.001 --> 00:06:06.001 There are a number of private automotive trade schools which offer good courses, 00:06:06.001 --> 00:06:09.001 but some of them have practical equipment such as this 00:06:09.001 --> 00:06:11.000 cutaway duplicate of a differential. 00:06:12.000 --> 00:06:16.000 You should never choose such a school, however, without thorough investigation. 00:06:17.000 --> 00:06:20.001 Ask your teachers or other authorities about them, or you can take a 00:06:20.001 --> 00:06:24.000 correspondence course, which also should be investigated. 00:06:25.000 --> 00:06:30.000 A correspondence course will be most valuable to you after you actually start 00:06:30.000 --> 00:06:34.000 working, for theory and practice carried on together will 00:06:34.000 --> 00:06:35.001 give you the most thorough training. 00:06:36.001 --> 00:06:41.000 However you get your training, study and hard work are necessary for you to 00:06:41.000 --> 00:06:45.000 become a superior mechanic, able to hold one of the better jobs. 00:06:52.000 --> 00:06:54.001 While you're still in high school, you can lay a strong 00:06:54.001 --> 00:06:56.001 foundation for automotive service. 00:06:57.001 --> 00:07:02.001 The gas engine produces power by burning fuel in a small enclosed space. 00:07:03.000 --> 00:07:05.000 In your physics class, you'll learn how this is done. 00:07:09.000 --> 00:07:13.001 In physics, you'll learn how the cooling system carries off the heat after power 00:07:13.001 --> 00:07:17.000 has been produced by the burning or combustion process in the engine. 00:07:19.000 --> 00:07:23.000 The transmission of the engine's power through gears and wheels to make the car 00:07:23.000 --> 00:07:27.001 move can be more clearly understood if you know the principles of physics. 00:07:31.000 --> 00:07:34.000 Electrical physics will help you understand the ignition of a car. 00:07:34.001 --> 00:07:39.000 So you can see that physics is not only an interesting subject, but very 00:07:39.000 --> 00:07:42.000 necessary if you were to become a first class auto mechanic. 00:07:45.001 --> 00:07:48.001 Take all the mathematics you can, for you'll need it in every 00:07:48.001 --> 00:07:50.001 type of automotive work you do. 00:07:53.001 --> 00:07:57.001 Mechanical drawing will help you in reading the many plans and illustrations in 00:07:57.001 --> 00:08:00.000 automotive textbooks and service manuals. 00:08:00.000 --> 00:08:03.001 This is especially important if you plan to become a shop foreman. 00:08:06.000 --> 00:08:10.000 In some of the larger public schools, the school shop is equipped to 00:08:10.000 --> 00:08:11.001 give practical automotive training. 00:08:12.001 --> 00:08:16.001 In others, this experience must be found in a service garage at the same time 00:08:16.001 --> 00:08:19.000 that automotive theory is studied in schools. 00:08:20.000 --> 00:08:25.001 School shop training of any kind will help you develop the coordination of hands 00:08:25.001 --> 00:08:30.000 and mind which is so important in all mechanical work. 00:08:32.000 --> 00:08:39.000 As an automobile service worker, you will have a responsibility for the safe, 00:08:39.001 --> 00:08:42.001 smooth, and economical operation of the cars on which you work. 00:08:43.000 --> 00:08:49.000 No matter what the size of the shop, there is one rule for success. Every job 00:08:49.000 --> 00:08:50.001 must be done right. 00:08:52.000 --> 00:08:56.001 If you develop the ability to manage a business, you may be promoted to garage 00:08:56.001 --> 00:08:59.001 manager, or you may be able to go into business for yourself. 00:09:00.001 --> 00:09:03.001 For this, you'll need to know something about bookkeeping, 00:09:04.000 --> 00:09:06.000 salesmanship, and business management. 00:09:08.001 --> 00:09:13.001 If you really like to use tools and have a knack for mechanical work, learn all 00:09:13.001 --> 00:09:15.001 you can about it at your local service garage. 00:09:16.001 --> 00:09:20.001 You'll find some things you may not like, but the dirt and grease will wash off. 00:09:23.000 --> 00:09:28.001 Try tinkering with an old car and rebuilding it. Do the best job you can, just as 00:09:28.001 --> 00:09:30.001 though some car owner depended on you. 00:09:31.000 --> 00:09:34.000 When you're finished, you may have found your life work. 00:09:35.000 --> 00:09:40.000 Thousands of new automobiles are manufactured every year. Although many of them 00:09:40.000 --> 00:09:44.000 replace cars which are worn out, the total number of motor vehicles will probably 00:09:44.000 --> 00:09:46.001 continue to increase for some time to come. 00:09:47.000 --> 00:09:51.000 If you qualify yourself, there is a reasonable possibility that you will find 00:09:51.000 --> 00:09:53.000 employment in the automotive service field.
