You might think that a diesel technician spends most of their day working on diesel engines. And you’re right—diesel techs do spend a lot of time working on big truck engines, but their responsibilities are varied, keeping work life interesting with new daily challenges.

Here’s a glimpse of life at Master Fleet to help you learn what a diesel technician does every day.

A Tech’s Job is More Than Diesel Engine Repair

As a trucking industry leader in the maintenance and repair field, Master Fleet relies on its diesel technicians to keep Wisconsin’s trucks and trailers up and running. Our technicians not only do diesel engine repair work, they also:

  • Complete DOT inspections

  • Diagnose and troubleshoot complex issues

  • Perform preventative maintenance

  • Review work orders

  • Support training and safety functions

  • Work with colleagues to ensure customer satisfaction

Our diesel techs also work closely with customers to ensure their engines and trucks function at peak performance. They’ll talk with drivers about repair decisions, parts, and updates, and their expertise ensures that customers can rely on them for quality service and support.

With Service Centers in Green Bay, Milwaukee and Neenah and 10+ Mobile Service Centers, Master Fleet diesel technicians also work in a variety of locations and environments.

No Two Days at Master Fleet are Ever the Same

As technology and customer needs evolve, we can promise an ever-changing work environment that fosters learning and prevents burnout.
