These manuals refer to engines found in trucks produced by Kenworth and Peterbilt, which are intended for heavy-duty commercial use and thus require reliable performance of the engines. The manuals provided by us include support for engine types such as MX-13, MX-11, and PX series. Depending on the type of engine, the manuals may contain information about repair and overhaul, fuel system, aftertreatment, electric circuits, diagnostic trouble codes, diagnostic procedures, and torque specs. It may be beneficial for mechanics to have the right manual at hand when investigating the issue rather than replacing components without comprehending their origin. The manuals may be useful for fleet maintenance specialists, diesel mechanics' shops, owner-operators, and technicians. When selecting a manual, one needs to find out the engine type and serial numbers first.
