Mack Trucks was founded in 1900 as the Mack Brothers Company in New York and built its first trucks a few years later, establishing a reputation for strength that made Mack a leading American manufacturer of heavy commercial vehicles. The company adopted the Mack Trucks name in 1922 and has been part of the Volvo Group since 2000, building its trucks in Allentown, Pennsylvania.

Mack is known for rugged vocational trucks used in construction, haulage and refuse work, and for engineering its own powertrains. The Mack engine tradition runs from the early Thermodyne and Maxidyne diesels through the E-Tech and E7 generations to today's MP7, MP8 and MP10 engines, all designed for long life under heavy loads. Mack engine designs have also appeared in buses and military vehicles over the years, broadening the reach of the service literature collected here.

Workshop manuals for Mack engines provide factory procedures for mechanical overhaul, fuel systems and electronic unit injection, turbocharging and emission controls, cooling and lubrication, electrical systems with wiring diagrams, torque specifications and diagnostic routines. Listings also cover the electronic engine controls used for troubleshooting modern Mack trucks. Rebuilders use the same factory data when remanufacturing cores to exchange standard, which keeps older Mack engines in service economically.

These documents are written for fleet maintenance departments, owner-operators, independent truck repair shops and engine rebuilders. With correct factory specifications, Mack engines can be serviced to deliver the durability and uptime the brand is known for.
