This factory service and repair manual for the 1991 Chevrolet W6500 Tiltmaster covers a straight truck with a low tilt cab, built to model code W6R042 and powered by one diesel — an inline-six of 5.8 liters and 353 cubic inches, turbocharged. Everything downstream of that is simplified. The fuel, air, cooling and control material addresses a single configuration, and the chassis chapters follow one vehicle from the front axle back through the driveline to the rear of the frame.

Known issues on the 1991 W6500 Tiltmaster. No recall stands against this truck, and no owner has raised a complaint about it with NHTSA. In place of a defect history, the manual gives working detail: procedures and specifications for the turbocharged 353-cubic-inch six, torque values for the fasteners that hold it together, wiring diagrams for the cab and chassis circuits, and diagnostics for the brake, steering and driveline systems that a loaded truck leans on hardest. That is the ground it is meant to be bought for.
