Diesel technology or heavy equipment mechanics programs cover diagnostic techniques, electronics, and related subjects. Programs may last 1 to 2 years and lead to a certificate. Other programs, which lead to associate's degrees, generally take 2 years to complete. These degree programs mix classroom instruction with hands-on training, and include courses on diesel technology, repair techniques, performance optimization, and equipment tooling.
Students learn how to interpret technical manual diagrams and electronic diagnostic reports. Automotive technicians receive extensive on-the-job training, and trainees are assigned basic tasks, such as cleaning parts, checking fuel and oil levels, and driving vehicles in and out of the shop. After they learn routine maintenance, trainees move on to vehicle inspection and diagnostics, at which point a trainee is usually considered a journey-level mechanic. Employers often send experienced mechanics to special training classes conducted by manufacturers and vendors to learn about the latest diesel technology.
Certification from the National Institute for Automotive Service Excellence (ASE) is the standard credential for diesel and other automotive service technicians. Diesel technicians may be certified in drivetrains, electronic systems, and preventative maintenance and inspection. To earn certification, auto mechanics must have 2 years of work experience and pass one or more ASE exams. To remain certified, diesel technicians must pass a recertification exam every 5 years. Many diesel mechanics are required to have a commercial driver's license so that they may test-drive buses and large trucks.
In this episode of deconstruction, Nate walks us through a 24v cummins diesel engine rebuild. Our diesel mechanic shares tips and tricks on how to rebuild the cummins piston rings, piston rods and cylinder sleeves.
Learn how to replace your brakes yourself. This video covers every step, including how to remove and install pads and rotors, where to apply brake grease, how to grease the guide pins, and how hard to torque the bolts for a safe and complete brake job.
In this episode of Saturday Mechanic, Ben Wojdyla explains the basics on how an ignition system operates and how it has evolved over the years.
This video covers replacing the pilot bearing, the throwout bearing which engages the pressure plate via the clutch fork, and finally the rear main seal because it may cause oil leaks in higher mileage motors.
This video will show you in depth how to change the inner and outer tie rods of your car or truck. You need a special tool, an inner tie rod end tool, to complete the job. This can be rented at your local parts store.
Diesel service technicians and mechanics held about 278,800 jobs in 2021. The median annual wage for diesel service technicians and mechanics was $45,170 in May 2021. The lowest 10 percent earned less than $29,070, and the highest 10 percent earned more than $67,550. Most technicians work full time, and overtime is common, as many repair shops extend their service hours during evenings and weekends. Many diesel mechanics, especially those employed by truck fleet dealers and bus companies, receive a commission in addition to their base salary.
In addition, a growing number of technicians are required to work on vehicles that use electricity or alternative fuels, such as ethanol. ASE certification is available in nine different automobile specialty areas: automatic transmission/transaxle, brakes, light vehicle diesel engines, electrical systems, engine performance, air-conditioning, drive train, steering, and suspension. To become certified, technicians must have at least 2 years of experience and pass an exam. Technicians who achieve certification in all of the foregoing areas may earn ASE Master Technician status.
