Diesel engine mechanics maintain and repair economic engine

Diesel engines are thundering across the state. Due to their fuel efficiency and durability, they are the preferred engine used in heavy-duty trucks, buses, and other large vehicles. These complex engines need skilled technicians to repair and maintain the vehicles that keep the economy moving.

During regular maintenance checks, diesel mechanics and technicians work through a checklist and inspect brake systems, steering mechanisms, wheel bearings, and mechanical systems. Repairing diesel engine vehicles generally requires the use of many different tools.

There were about 4,300 diesel mechanics in Oregon in 2008. Transportation and warehousing industries employed an estimated 1,20 diesel mechanics, the highest percentage of diesel engine mechanics (28%). The statewide median wage for a diesel engine mechanic is an estimated $20.92 per hour.


The minimum education requirement for diesel engine mechanics is long term on-the-job training. However, those who have completed formal training through a community college, vocational school, or apprenticeship will have a competitive edge. Diesel mechanics are also typically required to have a commercial driver's license.
