How To Get A Job As An Auto Mechanic Or Automotive Service Technician




With nearly every adult owning at least one vehicle today,  skilled, reliable Auto Mechanics often play a very prominent part in our lives.
Successful Otto Mechanics are honest, detail oriented, well-organized, patient, observant, and have good analytical, diagnostic, and reasoning skills.  They are also mechanically minded.  It is essential that Auto Mechanics have excellent customer service skills.  Auto Service Technicians must be able to read well as they must keep up to date with all the latest advances in auto technology.
Auto Mechanics must be physically fit as their work involves bending, stooping, lifting and carrying.  Tools must be kept in good working order and the work area must be kept clean and neat to avoid accidents.  Most Mechanics work a regular forty hour week, although some overtime may occasionally be required.
There is an ongoing need for dependable, skilled, well-trained  mechanics.
If you get a job as an Automotive Service Technician your duties may vary depending on where you work, and the level of your experience.  In general, Auto Mechanics conduct routine maintenance, following an established check list,  change oil, rotate tires, and lubricate engines.  If the client reports a problem, the Mechanic considers their opinions, does a preliminary inspection of the vehicle involving visual observations, running the engine, and possibly a test drive.  They then perform diagnostic tests, discuss a course of action with the client, make repairs, repair or replace worn parts, take the car for another test drive, and again report to the client.  When the client picks up the vehicle, the Auto Mechanic may explain in detail what they have done, answer clients’ questions, and possibly give advice.
There are various places you may find employment if you become an Auto Mechanic.  These include car dealerships, auto repair centers, and car rental agencies.  Some Auto Mechanics have their own shops and others go on to teach auto mechanics.


Education
If you are still in high school and have already decided that you would like to get a job as an Auto Mechanic, take courses in mathematics, English, computers, physics, chemistry, book-keeping, and any auto shop or mechanical training available.
You must have at least a high school diploma or GED.
To be competitive, you must then get formal training in auto mechanics.  Such training is available in trade schools, technical schools, vocational schools, and community colleges.  Courses last from one to two years, and are a combination of academic learning and hands-on experience.  You can get an associates’ degree in auto mechanics from a community college.  An associates’ degree would be a decided advantage.
There are some apprenticeship training programs available which are a good option for those who do not wish to commit to a longer training period.
Do some investigating before you choose a training program.  Some have age restrictions.  Make sure to choose a program that is certified by the National Institute for Automotive Service Excellence.  Such courses will prepare you to get your Automotive Service Excellence Certification.  Certification is now being demanded by many employers.
There are eight areas for certification including such specialties as brake systems, suspension and steering, electrical systems, engine repair, heating and air-conditioning, etc.  To get a certification, you must have two years experience and pass a certification exam.  Those who become certified in all eight areas will obtain the title of Master Automobile Technicians.
When you are looking for employment it is always wise to find a shop that, guarantees your future by offering opportunities for obtaining advanced professional development.















Machinists use their skill, and knowledge of plastics, and metals such as steel, aluminum, titanium, and silicon, to make integral parts for all types of machinery and a myriad of everyday items.  They may make only a unique, one-of-a-kind item, several of a kind, or, on occasion, many.  The number will largely govern the method used.
Machinists use blueprints, lathes, drill presses, grinders, milling machines, hard and software, as well as automated devices, to plan, cut, and shape perfect and precise,  machine parts.  Machinists often use safety devices such as goggles and ear plugs.
If you want to get a job as a Machinist, you must be mechanically minded, precise, detail oriented, and have good problem solving skills.  You must be able to concentrate totally on the task at hand and be able to work independently.  Good hearing would help you detect excessive vibration or rough cutting of the machinery.
Machinists today work in relatively clean surroundings.  If you want to get a job as a Machinist, you must be physically fit, able to stand for long hours and on occasion lift heavy loads.  Work days are usually of eight hours duration but overtime is not uncommon.
In spite of the advances of computer assisted production, there are still excellent opportunities available for skilled Machinists.
Those that get a job as a Machinist will start off a task by first studying specifications and blueprints.  They will then decide what tools are needed and what each step in the plan of procedure will be.  They must mark out where they will cut or bore, and ascertain the rate the metal must be fed into the machinery.  To do any job properly, Machinists must understand the properties of all the materials they work with and how they will react to heat, pressure, and cutting.  Machinery must be properly lubricated before each job, dull blades must be replaced, metal must be placed precisely, and controls must be set.  After each part is complete, it will be checked and measured to make sure it meets specifications.  Machinists today often use computer numerically controlled(CNC) machines.  The Machinist adjusts or programs the CNC machines and then the job can be completed by a Machine Operator.
Machine Operators work in the field of manufacturing and production.  They may operate machines of all kinds, or may specialize in one type of machinery.

Education
Those that wish to become Machinists must first get a high school diploma.  While in high school, it would be wise to take courses in English, mathematics, physics, trigonometry, calculus, and computers.  Also, take any courses available in metal working, drafting, blueprint reading, and mechanical drawing.  If possible get a part time job, paid or volunteer, in a metal-working shop.  Try to ‘shadow’ an experienced Machinist, or other professional, for a day or so, to get a real feel for the work they do.
Formal training for Machinists is available in technical schools and community colleges.  The associates’ degree program takes two years.  Some on-the-job training will also be required.  If available, select a program that provides apprenticeships or job placement.  Apprenticeship programs provide the opportunity to work as you learn under the guidance of experienced Machinists.
Graduate Machinists would be wise to obtain their certification, which is a testament to the level of their skill and knowledge.  Although certification is seldom required, it does increase job opportunities.
If you get a job as a Machinist, with sufficient education and experience, you can advance to positions as managers, supervisors, tool and die makers, or CNC programmers.  Some Machinists will eventually open their own businesses.
Machine Operators may also get training through formal training programs of up to one year, or through apprenticeship programs.
Both Machinists and Machine Operators will need to constantly upgrade their knowledge to keep up with rapidly advancing technology.

Crankshaft

Datsun built many variations of the L-series engine. As a result there are many combinations that can be used when building up any L-series to suit a range of purposes and to fit in with many racing rules.

In the case of the LD28 crankshaft which featured a 83mm stroke these have been used with many rod combinations. See my post regarding L14 rods, other combinations include the L24 rods apparently in the 73 240z they had 9mm rod bolts which are slightly stronger. However the L24E found in the early 80′s skylines and maxima’s in the US featured a small journal size and will not work with the LD28 crank.
The other commonly used rod is the L20A rod, again be careful of the L20E for the same reasons as the L24E rods. I have not been able to completely confirm this is the situation but am fairly certain. Carburetted L20′s like those found in the Fairlady S30 Z-L in Japan carry the suitable rods for the LD28 crank.
As you can see there are many combinations that are compatible with the LD28 crank. If you decide to use one of these cranks I would recommend trying to source one from New Zealand or failing that they often pop up on ebay in the US but by the time you pay shipping expenses/insurance and convert to US$ it becomes quite expensive.Another shot of the LD28 Crankshaft
I will cover any machine and prep work done to my LD28 crank in future articles stay tuned!

Part of Engine


Engine parts

 The engine-driven accessory bearings have a successful record of operating under the harsh conditions and severe environment of the engine bay, which includes high temperatures, freezing temperatures, vibrations, drastic load changes, and exposure to water, sand and dust.
Technologies applied to bearing and component materials and lubrication have resulted in products that operate with low friction, are compact, and have a long service life. These technologies contribute to improve fuel economy, high performance, and low noise.



*Careful inspection and disassembly of the valvetrain can teach you a lot. You want to look for misalignment and broken parts not only to find the problem, but to take a careful look at the non-broken cylinders to discover if damage could have been caused by problems such as bad valve adjustment, rockers slipping off the valve tips, or pushrod interference with guideplates or cylinder heads. A bent pushrod can also be telling. All we found was one bound-up exhaust spring and rocker.  





The innards of an internal combustion engine can be very intriguing, especially if you are trying to find the correct replacement parts for a particular engine. The auto makers are constantly redesigning internal engine parts not only from one model year to the next but even within a given model year. So you may need a VIN number as well as the year, make, model and engine size to correctly identify the application.
What parts the engine needs is the next concern. There are two approaches to major engine repair: piecemeal and complete. The piecemeal approach is to fix only that which is broken and leave the rest alone. The underlying motivation here is primarily economic. The vehicle and/or engine may not be worth spending much money on, so only those parts that absolutely have to be replaced to keep the engine running are replaced. Other repairs can wait for the next owner or the junkyard. This approach may skimp on needed machine work and attempt to "make do" with standard sized replacement parts such as bearings, rings, pistons and valves.
The other approach is to do a complete overhaul when the engine needs major repairs. This is obviously the more expensive approach, but one that usually provides much longer-lasting results. By replacing major wear components such as the rings, pistons, bearings, oil pump, valve guides, exhaust valves, valve springs, timing chain or belt, etc., the engine is restored to "like-new" condition and should deliver another 60,000 or more miles before repairs are needed again. This approach may involve the purchase of an engine kit or buying the parts individually. It usually also requires machine work such as turning the crank, overboring the cylinders, refacing the valves and seats, resurfacing the cylinder head(s), and maybe align boring or honing an overhead cam head and/or the main bores in the block.
Of course, there are shades of gray between these two, also. An engine may need a valve job but also has some wear in the cylinders. It is a judgment call as to whether it is worth it or not to do both. In some cases, the improved compression that comes from the valve work may increase blowby into the crankcase if the rings and cylinders are worn.
The important point here is to decide what parts may be needed to fix a particular engine problem, and then to replace any additional parts that might be needed.

Automotive service technicians and mechanics fix cars or light trucks that have broken down. They must be able to figure out the source of the problem quickly and correctly. They must know automobiles well.
The type of work they do has changed over the years. It used to be simple mechanical repair. Today it is a high technology job. Cars and trucks today are run by electronic systems and computers. The computers tell the automotive service technicians and mechanics how well the car or truck is performing. To do their job, technicians must know a lot about how complex parts of the car and truck work together. They must be able to work with electronic equipment that tells them what is wrong. They must be able to read and understand manuals and machines that are computer-based. At the same time they must be able to use the power and hand tools they have used in the past. They usually follow a checklist to make sure that they check every critical part, including belts, hoses, plugs, and brake and fuel systems. In fact, there are so many parts to an automobile that some mechanics specialize in fixing only one certain part of it. For example, some technicians will only fix brakes while others will only work on problems with the air-conditioning system.
Many automotive service technicians work more than 40 hours a week. Many who put in long hours work for themselves. Some service shops are open in the evenings and on weekends.
Most service technicians work indoors in repair shops. Many times technicians must work with dirty and greasy parts. They often lift heavy parts and tools. Minor cuts, burns, and bruises are common. Technicians usually avoid serious accidents when the shop is kept clean and in order. It is also important that they follow safety practices.


Common Steps To A Quick Automotive Check-Up
Your car needs regular servicing in order to continue running smoothly. The good news is that even though a mechanic can do everything for you, most of it can be done in your garage. We’re not talking about overhauling your engine or transmission. We’re referring to the little things that can influence your car’s performance, maneuverability, and handling over time. Below, I’ll provide a 6-step checklist that you can use to make sure your vehicle is in tip-top condition.
