1991 GMC/Chevrolet Medium-Duty Truck Unit Repair Service Shop Manual. Original.
This manual includes procedures involved in disassembly and assembly of components listed in the table of contents. For major components such as diesel engine, drive axle, and transmissions not covered in this manual, refer to the component manufacturer's service manual (NOT Included). For Steel Tilt Cab Models, refer to the Forward Service Manuals Form No. X-9066 (NOT Included) and X-9067 (NOT Included).
Note: Service manuals can be valuable tools when working on and/or restoring a vehicle. For the uninitiated, keep in mind that these manuals were never meant as restoration manuals, as that is not within the regular scope of work done by dealership service departments (even today).
Condition: Service Manuals are used in Dealership Shops, Independent Garages and in Fleet Environments and thus can reflect such use, most often showing extensive signs of soiling, age, and wear. The information within is still legible and can give valuable insight. The images shown are representative of what is shipped.
