service man is really for mechanics and one he must be able to make all repairs in the engine such as repairing or replacing the camshaft he must understand all types of engines thoroughly all although all gas engines are fundamentally the same differences have been developed in the various makes of cars which the mechanic must know for example in cleaning out carbon and grinding valves he may work on the l-head type engine one time while the next engine may be the overhead valve type both types provide efficient power but the problems of adjusting them are totally different a good service man is also a machinist in an emergency he may be called upon to make completely some minor part which may not be in the stock of repair parts the superior service man is a welder through accidents and even ordinary usage parts are broken and have to be repaired the expert welder is valuable to any garage and often concentrates on specialized work at very good pay in addition the all-round service man is an electrician and must have the knowledge and skills to keep the automobiles electrical system in working order but without the spark to fire the engine there would be no power in the early days electrical energy was supplied by dry batteries but the car of today carries its own generating and storage plant the storage battery is of low voltage so a coil and condenser is necessary to step up the current enough to jump the spark in the spark flood the callin distributor also must be tested and kept in proper working order besides the ignition system there are the lighting and starting circuits would sometimes need the services of a competent mechanic the use of heaters windshield wipers and radios has further increased and complicated the electrical work of the service man because of the high speed at which vehicles travel today the care and adjustment of brakes is a serious and vital part of the service man’s work the safety of the car on the highway largely depends on good brakes along with correct and accurate alignment of the wheels radiator repair and general care of the cooling system is important and making cars run efficiently and economically so soldering is another of the many kinds of work the service man must do in the larger garages the man who becomes expert and servicing engines may find specialized work on engines only there are body and fender shops which employ men who are specialists in that line there are battery and electrical shops and other shops which make brake testing and wheel aligning the principal part of their business for any of these jobs are thorough training and general service work is valuable there is an opportunity in the larger garages for the service man to advance to service manager or to become a troubleshooter besides technical knowledge and skill these jobs require the ability to meet the public to make a good impression and to explain clearly the work that needs to be done or that has been done some servicemen become automobile salesmen if they have sales ability they are usually successful because they have the advantage of really understanding the cars they sell if you enter

many parts of an automobile and their relationship to each other you will learn about new vacations and other operations in automobile upkeep while doing these jobs you must be alert to learn everything you possibly can you must also study constantly in your spare time as a basis for study there are numerous service manuals put out by the automobile manufacturers to help train servicemen to do their work correctly these manuals are full of accurate information and they’re interesting to study because of their detailed diagrams and illustrations there are many good books on automotive service in your school or public library be sure to select books which are up to date however as automobiles are constantly being improved most automobile manufacturers provide training courses for their service men regular training conferences are held for employees in the more up-to-date garages the manager shop foreman or some other expert discusses the newest automobile developments and how to service them properly movies and slide films are sometimes shown in the local shop manuals for further study are provided along with the films you should never miss such opportunities to learn if you expect to become a successful mechanic another way to learn while working is to attend evening classes dealing with the fundamental principles of the automobile these classes are conducted in the

been produced by the burning or combustion process in the engine the transmission of the engines power through gears and wheels to make the car move can be more clearly understood if you know the principles of physics electrical physics will help you understand the ignition of a car so you can see that physics is not only an interesting subject but very necessary if you were to become a first
