This factory service and repair manual for the 1989 Chevrolet W4500 Tiltmaster deals with 236 cubic inches of turbocharged diesel in an inline-four, the only engine offered, and with one body: a straight truck on the low tilt cab. The single W4S042 specification runs through the whole book. Because a medium-duty truck spends its life loaded, the sections that matter most — driveline, braking, suspension and the diesel fuel system — are given as procedures with specifications and torque values rather than as general description.
